Abstract

The invention relates to a multiband antenna, especially for mobile radiotelephone service devices with a multi-side support (1) and two or more circuit-board conductors (2, 3) representing the transmitting and/or receiving device in different levels of the support (1). According to the inventive antenna, at least two circuit-board conductors (2, 3) are connected to each other via a direct contact (6). In an ideal embodiment, the inventive antenna is a multiband antenna which can cover different frequency ranges in such a way that the capacity utilisation of the networks and roaming at home and abroad is improved. A simple design for a function in several frequency bands is possible. Short-term fine tuning of the antenna is possible. The possibilities of tuning the individual circuit-board conductors is optimised, especially with regard to a combination of directly contacting circuit-board conductors and additional coupled circuit-board conductors.

Multiband-AntenneMultiband antenna
Die Erfindung bezieht sich auf eine Multiband-Antenne mit den oberbegrifflichen Merkmaien des Patentanspruchs 1.The invention relates to a multiband antenna with the generic features of claim 1.
Im Bereich der Funktechnik, insbesondere Mobilfunktechnik werden Multiband-Antennen benötigt, die verschiedene Frequenzbereiche abdecken, um z.B. die Auslastung der Netze und das Roaming im In- und Ausland verbessern zu können.In the field of radio technology, in particular mobile radio technology, multiband antennas are required that cover different frequency ranges, e.g. to be able to improve network utilization and roaming at home and abroad.
Insbesondere sollen die Antennen auch für einen breitbandigen Frequenzbereich auslegbar sein. Um eine weitere Verkleinerung der Mobilfunkgeräte zu ermöglichen, sollten diese Antennen nur geringe Abmessungen und ein geringes Gewicht aufweisen. Außerdem müssen diese Antenne billig und reproduzierbar herstellbar sein.In particular, the antennas should also be able to be designed for a broadband frequency range. In order to enable a further downsizing of the mobile radio devices, these antennas should have only small dimensions and a low weight. In addition, this antenna must be cheap and reproducible to manufacture.
Bisher wurde versucht das Problem mit Helixantennen, Mikrostreifenantennen, beidseitigen und mehrlagigen PCB- Antennen oder dem gleichzeitigen Einsatz mehrerer Antennen zu lösen.So far, attempts have been made to solve the problem with helical antennas, microstrip antennas, double-sided and multilayer PCB antennas or the simultaneous use of several antennas.
Aus der WO 96/38881 und der WO 96/38882 sind z.B. Multiband- Antennen bekannt, bei denen auf zumindest einer Seite einer Leiterplatte mehrere Leiterbahnen als Strahlungskörper angeordnet sind. Nur eine der Leiterbahnen ist mit einem Sender/Empfänger verbunden oder z.B. als einfaches strahlendes Element ausgebildet. Weitere Leiterbahnen sind nicht direkt über elektrische Leiter verbunden, sondern sind derart ausgebildet, daß sie durch eine elektromagnetische Kopplung angeregt werden. Insbesondere die Abstimmung der Leiterbahnen gestaltet sich dabei sehr schwierig und aufwendig.From WO 96/38881 and WO 96/38882 e.g. Multiband antennas are known in which a plurality of conductor tracks are arranged as radiation bodies on at least one side of a printed circuit board. Only one of the conductor tracks is connected to a transmitter / receiver or e.g. designed as a simple radiating element. Other conductor tracks are not connected directly via electrical conductors, but are designed in such a way that they are excited by an electromagnetic coupling. In particular, the coordination of the conductor tracks is very difficult and complex.
Die bekannten Lösungen haben jedoch verschiedene Nachteile, wie folgt: Die sogenannten Helix-Antennen, die nur einen heiisch gewundenen Draht aufweisen, sind kompliziert abzustimmen, benötigen viel Platz und machen lange Werkzeugvorlaufzeiten erforderlich. Zudem besteht das Problem, daß nicht alle denkbaren Steigungen und Formen wickelbar sind.However, the known solutions have several disadvantages, as follows: The so-called helix antennas, which only have a helically twisted wire, are complicated to coordinate, take up a lot of space and require long tool lead times. There is also the problem that not all conceivable gradients and shapes can be wound.
Bei Mikrostreifenleitungs-Antennen wird eine Massefläche benötigt, die die Rückseite einer gedruckten Leiterplatte (PCB) vollständig abdeckt. Durch den erforderlichen Abstand zu den strahlenden Elementen ist zudem ein großer Platzbedarf erforderlich. Auch diese Antennen sind bei der Herstellung kostenintensiv.Microstrip line antennas require a ground plane that completely covers the back of a printed circuit board (PCB). The required distance from the radiating elements also requires a large amount of space. These antennas are also expensive to manufacture.
Auch bei beidseitigen PCB-Antennen oder zwei PCBs mit jeweils einer strahlenden Struktur auf einer Seite der beiden PCBs und mit einer verlängerten Masse zum Abstimmen auf einer Rückseite einer der beiden PCBs, die hintereinander gelegt werden, bestehen Nachteile. So bestehen bei diesen eine geringere Multibandfähigkeit und weniger Möglichkeiten zur Abstimmung. Zudem wird eine Massezuführung benötigt.There are also disadvantages with double-sided PCB antennas or two PCBs, each with a radiating structure on one side of the two PCBs and with an extended mass for tuning on the back of one of the two PCBs, which are placed one behind the other. So there is less multi-band capability and fewer options for tuning. A mass supply is also required.
Mehrlagige PCB-Multiband-Antennen sind in der Herstellung aufwendiger und haben eine geringere Reproduzierbarkeit.Multi-layer PCB multiband antennas are more complex to manufacture and have a lower reproducibility.
Die Verwendung mehrerer Antennen zur Abdeckung von mehreren Bändern macht einen höheren Platzbedarf, eine zusätzliche Ansteuerung der einzelnen Antennen, eine zusätzliche Antennenkontaktierung und eine zusätzliche Antennenhalterung erforderlich. Dabei erhöht sich dementsprechend auch die Anzahl der Bauelemente. Auch diese Lösung ist bei der Herstellung kostenintensiv.The use of several antennas to cover several bands requires more space, additional control of the individual antennas, additional antenna contacting and an additional antenna holder. The number of components also increases accordingly. This solution is also costly to manufacture.
Die bisherigen Konzepte wie Helix-Draht-Antennen, Mikrostreifenleitungs-Antennen, beidseitige PCB-Antennen mit Kopplung und mehrere Antennen neben- oder hintereinander haben insbesondere alle den Nachteil, daß sie entweder einen zu hohen Platzbedarf haben oder die Abstirnmbarkeit bei einer Multiband-Funktion nicht ohne weiteres möglich ist.The previous concepts such as helix wire antennas, microstrip line antennas, double-sided PCB antennas with coupling and several antennas side by side or in series all have the disadvantage in particular that they are either one have too much space or it is not easily possible to use a multiband function.
Die bekannten Systeme sind mit Blick auf die Abstirnmbarkeit auch nachteilhaft, da dafür durch eine Vielzahl von zeitintensiven Arbeitsgängen ein großer Zeitaufwand bei der Entwicklung erforderlich ist. Beispielsweise sind bei der Stanz-Biege-Technik und der gewickelten Helix Simulationen erforderlich, wobei das umgesetzte Ergebnis meistens nochmals korrigiert werden muß, da Simulation und Praxis in der Regel nicht ausreichend übereinstimmen. Bei der Stanz-Biege-Technik kommt weiter hinzu, daß eine Werkzeugänderung länger dauert oder im Extremfall im Endstadium unter Umständen gar nicht möglich ist. Mehrlagige Antennen mit mehr als zwei Lagen haben den Nachteil, daß sie in vielen Labors nicht ohne weiteres ätzbar sind, da die Technik im Haus nicht vorhanden ist und man die Tests mit dem Zulieferer zusammen fahren muß.The known systems are also disadvantageous in terms of their ability to be removed, since a large amount of time is required in the development due to a large number of time-consuming work steps. For example, the punching and bending technique and the wound helix require simulations, and the implemented result usually has to be corrected again, since simulation and practice generally do not match sufficiently. The punching and bending technique also means that changing the tool takes longer or, in extreme cases, may not even be possible in the final stage. Multi-layer antennas with more than two layers have the disadvantage that they cannot be easily etched in many laboratories, since the technology is not available in-house and the tests have to be carried out with the supplier.
Die Aufgabe der Erfindung besteht darin, eine verbesserte Antenne mit Multibandfähigkeit vorzuschlagen.The object of the invention is to propose an improved antenna with multi-band capability.
Diese Aufgabe wird durch eine Antenne mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand von abhängigen Ansprüchen.This object is achieved by an antenna with the features of claim 1. Advantageous refinements are the subject of dependent claims.
Die vorgeschlagene Antenne ist idealerweise eine Multiband- Antenne, die verschiedene Frequenzbereiche abdecken kann, so daß die Auslastung der Netze und das Roaming in In- undThe proposed antenna is ideally a multiband antenna that can cover different frequency ranges, so that the utilization of the networks and the roaming in and
Ausland verbessert werden. Dabei ist eine einfache Auslegung für eine Funktion in mehreren Frequenzbändern möglich.Abroad to be improved. A simple design for a function in several frequency bands is possible.
Eine weitere Verkleinerung der Mobilfunkgeräte wird ebenfalls ermöglicht, da die Abmessungen der Antennen und deren Gewicht reduzierbar sind. Insbesondere ist eine Verringerung der erforderlichen Gesamthöhe möglich. Außerdem sind diese Antennen kostengünstig herstellbar, da z.B. im Fall einer Antenne für zwei Frequenzen nur zwei Leiterbahnen erforderlich sind. Außerdem ist keine Masse erforderlich, was den Aufbau zusätzlich vereinfacht.A further downsizing of the mobile radio devices is also made possible, since the dimensions of the antennas and their weight can be reduced. In particular, a reduction in the total height required is possible. In addition, these antennas can be produced inexpensively, since only two conductor tracks are required, for example, in the case of an antenna for two frequencies. In addition, no mass is required, which further simplifies the construction.
Derartige Antennen sind durch geringe Toleranzschwankungen in der Produktion auch problemlos reproduzierbar. Besonders vorteilhaft ist, daß eine solche Antenne besonders einfach auf verschiedenste Art und Weise abstimmbar ist. Insbesondere ist auch eine kurzfristige Feinabstimmung der Antenne möglich. Eine Antenne kann im eigenen Labor kurzfristig aufgebaut werden, z.B. in einem halben Tag, bei Bedarf einschließlich Ätzen oder Fräsen der Struktur. Die Daten können dann an den Leiterplattenhersteller weitergegeben werden, der dann ebenfalls zügig, z.B. innerhalb eines Tages, ohne Umsetzungsprobleme eine neue Maske herstellt, mit der dann die Massenproduktion aufgenommen werden kann. Auch ist es möglich auf dieser Grundlage zusätzliche Test durchzuführen.Such antennas are also easily reproducible due to low tolerance fluctuations in production. It is particularly advantageous that such an antenna can be tuned particularly easily in a wide variety of ways. In particular, a short-term fine-tuning of the antenna is also possible. An antenna can be set up at short notice in your own laboratory, e.g. in half a day, including etching or milling the structure if necessary. The data can then be passed on to the circuit board manufacturer, who then also quickly, e.g. creates a new mask within one day, without implementation problems, with which mass production can then be started. It is also possible to carry out additional tests on this basis.
Besonders vorteilhaft ist die Kombination einer Zwei-Ebenen- PCB-Antenne mit einer oder mehreren Durchkontaktierungen und/oder einer oder mehreren Stirnseitenkontaktierungen. Diese Kombination erweitert und vereinfacht die Möglichkeiten der Abstimmung der Gesamtanordnung. So wird es möglich, eine besonders platzsparende, billige und verhältnismäßig einfach abstimmbare Multiband-Antenne bereitzustellen.The combination of a two-level PCB antenna with one or more vias and / or one or more face contacts is particularly advantageous. This combination extends and simplifies the possibilities of coordinating the overall arrangement. This makes it possible to provide a particularly space-saving, cheap and relatively easily tunable multiband antenna.
Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung erläutert. Es zeigen:An embodiment of the invention is explained below with reference to the drawing. Show it:

Wie aus Fig. 1 ersichtlich, besteht eine beispielhafte Zwei- Ebenen-PCB-Multiband-Antenne aus einem Träger in Form einer Leiterplatte 1, die hier abgesehen von ihren Außenkonturen durchsichtig dargestellt ist. Die Leiterplatte 1 trägt auf beiden Seiten eine bzw. mehrere strukturierte Leiterbahnen 2 und 3. Die Leiterbahn 2 ist über eine Kontaktierfläche 12 an eine Sende-/Empfangsschaltung anschließbar.As can be seen from FIG. 1, an exemplary two-level PCB multiband antenna consists of a carrier in the form of a printed circuit board 1, which is shown transparently here apart from its outer contours. The circuit board 1 carries one or more structured conductor tracks 2 and 3 on both sides. The conductor track 2 can be connected to a transmitting / receiving circuit via a contact surface 12.
Die Leiterbahnen 2 und 3 sind hier direkt miteinander elektrisch verbunden. Dadurch stellen sie einen oder mehrere elektrische Strahler dar, die bei zwei oder mehr Frequenzen Resonanzen zeigen. Die Resonanzfrequenzen sind durch Wahl des Ortes der elektrischen Verbindung, also der Verbindungspunkte der Leiterbahnen 2 und 3, und durch Wahl der Anordnungen und Formen der Leiterbahnen 2 und 3 frei wählbar.The conductor tracks 2 and 3 are electrically connected here directly. As a result, they represent one or more electrical radiators that resonate at two or more frequencies. The resonance frequencies can be freely selected by choosing the location of the electrical connection, that is to say the connecting points of the conductor tracks 2 and 3, and by selecting the arrangements and shapes of the conductor tracks 2 and 3.
Die Leiterbahnen 2 und 3 der beiden Ebenen sind also über eine oder mehrere Rand- und/oder Stirnseitenkontaktierungen 4 direkt elektrisch leitend verbunden.The conductor tracks 2 and 3 of the two levels are thus directly connected in an electrically conductive manner via one or more edge and / or end face contacts 4.
Anstelle der Kontaktierung über Stirnseiten 5 oder zusätzlich dazu kann die Kontaktierung auch an einer oder mehreren Stellen durch die Leiterplatte 1 hindurch erfolgen, wie dies beispielsweise in Fig. 2 anhand einer Durchkontaktierung 6 dargestellt ist.Instead of contacting via end faces 5 or in addition thereto, contacting can also take place at one or more points through the printed circuit board 1, as is the case here for example in Fig. 2 is shown with a via 6.
Zusätzlich zur bekannten kapazitiven, induktiven und Strahlungskopplung bietet die direkte elektrische Kontaktierung der Leiterbahnen 2 und 3 beider Ebenen eine neue Möglichkeit der Abstimmung der Gesamtanordnung.In addition to the known capacitive, inductive and radiation coupling, the direct electrical contacting of the conductor tracks 2 and 3 on both levels offers a new possibility of coordinating the overall arrangement.
Jede Leiterbahn kann jede beliebige Form annehmen. Insbesondere sind auf den Leiterbahnen auch Verzweigungen 7 möglich. So zeigt Fig. 3 eine beispielhafte Ausführungsform mit einer Randkontaktierung 8 im Bereich der Mitten derEvery trace can take any shape. In particular, branches 7 are also possible on the conductor tracks. 3 shows an exemplary embodiment with an edge contact 8 in the area of the middle of the
Leiterbahnen 2 und 3. Vorzugsweise haben eine oder mehrere der Leiterbahnen 2 und 3 die Form eines Mäanders, einer Schlangenlinie oder diejenige eines Stabes.Conductor tracks 2 and 3. Preferably one or more of the conductor tracks 2 and 3 have the shape of a meander, a serpentine line or that of a rod.
Wie aus Fig. 4 ersichtlich, können eine oder mehrere der Leiterbahnen 2 und 3 auch an einer oder an mehreren Stellen unterbrochen werden. Dadurch ist eine Kombination aus Direktverbindungen und Kopplungen zwischen Vorder- und Rückseite und auch Kopplungen zu weiteren über die durch die Unterbrechungen entstandenen Spalte 9 ausgebildeten und nicht direkt verbundenen Leiterbahnen 10 erzeugbar.As can be seen from FIG. 4, one or more of the conductor tracks 2 and 3 can also be interrupted at one or more points. As a result, a combination of direct connections and couplings between the front and rear sides and also couplings to further interconnects 10 which are formed via the gaps 9 and are not directly connected can be produced.
Es können auch zwei oder mehrere Strahler auf der Rückseite angebracht werden, die sowohl von der Vorderseite, als auch von der Rückseite durch Kopplung angeregt werden. Beispiele für eine Vielzahl weiterer Kombinationsmöglichkeiten sind aus den Fig. 5 und 6 ersichtlich.Two or more radiators can also be attached to the back, which are excited by coupling both from the front and from the back. Examples of a multitude of further possible combinations are shown in FIGS. 5 and 6.
Eine Antenne kann insbesondere auch aus mehreren Leiterplatten 1 mit jeweils einer oder mehreren Leiterbahnen und/oder Leiterplatten mit einer oder mehreren Leiterbahnen auf einer oder mehreren Lagen in solchen Leiterplatten aufgebaut sein, die beliebig zueinander angeordnet werden können. Die einzelnen Lagen und/oder Leiterplatten sind vorzugsweise, aber nicht zwingend, parallel zueinander. Der Abstand zwischen den Ebenen kann zusätzlich als Möglichkeit zur Abstimmung eingesetzt werden.An antenna can in particular also be constructed from a plurality of printed circuit boards 1, each with one or more conductor tracks and / or printed circuit boards with one or more conductor tracks, on one or more layers in such circuit boards, which can be arranged in any way relative to one another. The individual layers and / or printed circuit boards are preferably, but not necessarily, parallel to one another. The Distance between the levels can also be used as an option for coordination.
Das Material aus dem die Leiterplatte besteht ist frei wählbar, sollte aber hochfrequenztauglich sein, wie z.B. kommerzielles Leiterplattenmaterial FR4 oder ein flexibles Kunststoffmaterial, insbesondere eine Folie aus Polycarbonat oder Polyetherimid. Dabei können einzelne Leiterbahnen auch im Material eingeschlossen werden.The material from which the circuit board is made is freely selectable, but should be suitable for high frequencies, e.g. commercial circuit board material FR4 or a flexible plastic material, in particular a film made of polycarbonate or polyetherimide. Individual conductor tracks can also be included in the material.
Eine solche Antenne kann vorteilhafterweise auch direkt in eine Hauptbaugruppe integriert werden. In diesem Fall bietet sich z.B. auch die Möglichkeit durch eine Verzweigung der Zuleitung und unterschiedlich lange Umwegleitungen in den einzelnen Zweigen mehrere Speisepunkte auf den einzelnen der Leiterbahnen 2 und 3 bereitzustellen, um die Hauptbaugruppe mit verschiedenen Phasenlagen versorgen zu können. DieseSuch an antenna can advantageously also be integrated directly into a main assembly. In this case, e.g. also the possibility of branching the supply line and detour lines of different lengths in the individual branches to provide several feed points on the individual of the conductor tracks 2 and 3 in order to be able to supply the main assembly with different phase positions. This
Verzweigungsleitungen können auch auf dem Antennen-PCB selbst verwirklicht werden.Branch lines can also be implemented on the antenna PCB itself.
Weiterhin können eine oder mehrere Anpaß-Schaltungen auf dem Antennenträger selbst und nicht nur auf der Hauptbaugruppe angeordnet werden. Auch das Bereitstellen anderer Baugruppen, insbesondere elektronischer Elemente ist auf einer solchen Leiterplatte möglich, wobei solche Elemente optional auch mit den Leiterbahnen kommunizieren können, also z.B. aktiv durch die Signale auf den Leiterbahnen angesteuert werden können oder ihrerseits die Signale auf den Leiterbahnen beeinflussen oder vorgeben können. Furthermore, one or more matching circuits can be arranged on the antenna carrier itself and not only on the main assembly. The provision of other assemblies, in particular electronic elements, is also possible on such a printed circuit board, such elements optionally also being able to communicate with the conductor tracks, e.g. can be actively controlled by the signals on the conductor tracks or in turn can influence or specify the signals on the conductor tracks.
