Abstract

A cylindrical cavity resonator (HR) has a coupling aperture for an existing TE wavetype. The magnetic field lines of the TE11n waveform are formed tangentially to the cylindrical surface of the resonator. In the side wall of the unit a coupling slot (K) is located in the direction of the gamma component of the magnetic field. Ideally the slot is located at the max. magnetic field point. ADVANTAGE - Provides coupling between resonators.

Description

Die vorliegende Erfindung betrifft einen Hohlraumresonator mit mindestens einer in seiner Seitenwand vorgesehenen Koppelöffnung zur Ankopplung eines in ihm existenzfähigen TE Wellentyps.The present invention relates to a cavity resonator with at least one provided in its side wall Coupling opening for coupling a viable in it TE shaft type.

Aus der DE-A-36 21 298 ist es bekannt, an zylindrische Hohlraumresonatoren über in deren Seitenwände eingelassene Koppelöffnungen TE Wellentypen anzukoppeln. Hierbei sind die Koppelöffnungen so angeordnet und gestaltet, daß der jeweilige TE Wellentyp über die z-Komponente seines magnetischen Feldes angeregt wird.From DE-A-36 21 298 it is known to cylindrical Cavity resonators over embedded in their side walls Coupling openings to couple TE shaft types. Here are the Coupling openings arranged and designed so that the respective TE wave type via the z component of its magnetic field is excited.

Der Erfindung liegt die Aufgabe zugrunde, für einen eingangs genannten Hohlraumresonator eine weitere Ankopplungsvariante für TE Wellentypen anzugeben.The invention is based, for one called cavity resonator a further coupling variant to be specified for TE shaft types.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird nun die Erfindung näher erläutert.Using one shown in the drawing The invention will now be explained in more detail by way of example.

Fig. 1 zeigt einen zylindrischen Hohlraumresonator mit einer magnetischen Feldverteilung des TE11n Wellentyps und Fig. 1 shows a cylindrical cavity resonator with a magnetic field distribution of the wave type and TE11n

Fig. 2 zeigt einen Querschnitt A-A durch diesen Hohlraumresonator. Fig. 2 shows a cross-section AA through this cavity resonator.

Der Fig. 1 ist ein zylindrischer Hohlraumresonator HR zu entnehmen, in dem ein TE11n (n=1,2...) Wellentyp existenzfähig ist. In dem Hohlraumresonator HR sind einige der magnetischen Feldlinien (strichliert gezeichnet) des TE112 Wellentyps dargestellt. Die Fig. 1 zeigt eine perspektivische Draufsicht auf die magnetischen Feldlinien, und die Fig. 2 zeigt einen Querschnitt A-A durch das magnetische Feld. Wie die Fig. 1 und 2 zu erkennen geben, hat das magnetische Feld des TE11n (n=1,2...) auch eine γ-Komponente; das ist diejenige magnetische Feldkomponente, welche senkrecht zur Längsachse (z-Achse) des Hohlraumresonators HR orientiert ist und zwar tangential zu Zylinderflächen, welche konzentrisch sind zu der zylindrischen Seitenwand des Hohlraumresonators HR. FIG. 1 is shown in a cylindrical cavity resonator HR in which a TE11n (n = 1,2 ...) wave mode is viable. In the cavity resonator HR, some of the magnetic field lines (shown in broken lines) of the TE112 wave type are shown. FIG. 1 shows a perspective top view of the magnetic field lines, and FIG. 2 shows a cross section AA through the magnetic field. As shown in FIGS. 1 and 2, the magnetic field of the TE11n (n = 1,2 ...) also has a γ component; that is the magnetic field component which is oriented perpendicular to the longitudinal axis (z-axis) of the cavity resonator HR and tangentially to cylindrical surfaces which are concentric to the cylindrical side wall of the cavity resonator HR.

In der Seitenwand des Hohlraumresonators HR ist mindestens ein Koppelschlitz K vorhanden, der sich in Richtung der γ-Komponente des magnetischen Feldes des TE11n (n=1,2...) Wellentyps erstreckt. Ein so verlaufender Koppelschlitz K ermöglicht die Anregung des TE11n (n=1,2...) Wellentyps über die γ-Komponente seines magnetischen Feldes. Idealerweise wird ein solcher Koppelschlitz dort angeordnet, wo das magnetische Feld ein Maximum hat.In the side wall of the cavity resonator HR is at least a coupling slot K is present, which is in the direction of γ component of the magnetic field of the TE11n (n = 1.2 ...) Shaft type extends. A coupling slot K running in this way enables excitation of the TE11n (n = 1,2 ...) shaft type via the γ component of its magnetic field. Ideally such a coupling slot is arranged where that magnetic field has a maximum.

Über einen zuvor beschriebenen, in der Seitenwand eines Hohlraumresonators angeordneten Koppelschlitz kann ein weiterer Hohlraumresonator angekoppelt werden, der ebenfalls in der Seitenwand mit einem Koppelschlitz versehen ist.Via a previously described one in the side wall Cavity resonator arranged coupling slot can be further cavity resonator can be coupled, which also is provided with a coupling slot in the side wall.
