Abstract
The utility model belongs to an antenna for wireless mobile communication, which particularly relates to a microstrip antenna for mobile communication of HF, VHF, UHF and SHF wave bands. The basal plate of the microstrip antenna is composed of two positive and two reverse unclosing rectangular spirals, five positive and five reverse foldingly connected first unit radiation conduction bands and top loads. The formed gap is equal to the resonant slot of 1/2 wave length. The utility model has the characteristics of high gain, wide frequency band, isotropic directivity, easy conformation, etc., and is suitable for vehicle-mounted and carrier-borne microstrip antennas for mobile communication.
Description
The utility model belongs to the wireless mobile communications antenna, the mobile communication microstrip antenna of particularly a kind of HF, VHF that is used for radio communication, UHF, SHF wave band.
At present, in the radio communication at home and abroad, be applied to HF, VHF, UHF, the microstrip antenna of SHF wave band, its geometry all is a rectangle, circular, oval, grid shape, profile of tooth, triangle, polygon, annular, fan-shaped, single geometry microstrip antenna such as trapezoidal, its ubiquity gain is low, frequency band is narrow, end-fire is poor, only to the half space radiation, problems such as the antenna physical dimension is big, had a strong impact on communication distance, communication quality and communication efficiency, the validity of directional communication particularly, especially to the continuous mobile communication that changes of communication direction, influence bigger, the antenna physical dimension is big, has limited environment for use and service condition, also is unfavorable for conformal simultaneously.
The purpose of this utility model is to solve low, the problems such as frequency band is narrow, end-fire difference of gain, and a kind of suitable indoor and outdoor, fixing or tracking exchage microstrip antenna are provided.
Task of the present utility model is, on microstrip aerial substrate through printing or photoetching process make by amounting to of forming of a unit radiation conduction band, spiral shell around, slit, add roof construction mobile communication microstrip antenna, by 2 non-closed rectangular spiral shells of forward around, article 2, reverse non-closed rectangular spiral shell is formed a unit radiation conduction band around being connected, with the 2nd reverse non-closed rectangular spiral shell is the top load that adds of vertically amounting to composition of initial point around (15), one unit radiation conduction band through amount to spiral shell around after, the slit resonance of formation is in 1/2 wavelength.
The utlity model has gain height, bandwidth, isotropic directivity, in light weight, physical dimension is little, easily conformal, good concealment, not fragile, low cost and other advantages.
Specify with by way of example below in conjunction with accompanying drawing.
Fig. 1 shows mobile communication microstrip antenna structure figure.
With reference to accompanying drawing 1, the mobile communication microstrip antenna on antenna substrate by amounting to, spiral shell around, the slit, the mobile communication one unit radiation conduction band that adds roof construction is formed, with initial point (1) clockwise direction to terminal (2) the 1st the non-closed rectangular spiral shell of forward around, with initial point (2) clockwise direction to terminal the 1st forward of (3) amount to, counterclockwise oppositely amount to for (4) the 1st time to terminal with initial point (3), with initial point (4) clockwise direction to terminal the 2nd forward of (5) amount to, counterclockwise oppositely amount to for (6) the 2nd time to terminal with initial point (5), with initial point (6) counterclockwise to terminal (7) be the 1st reverse non-closed rectangular spiral shell around, with initial point (7) clockwise direction to terminal (8) be the 2nd non-closed rectangular spiral shell of forward around, with (7) is that boundary's point forms 2 continuous amounting to, spiral shell is around structure, reach and promptly widen frequency band, do not reduce the purpose of gain again.With initial point (8) clockwise direction to terminal (9) be that the 3rd forward amounted to, with initial point (9) counterclockwise to terminal (10) be oppositely to amount to for the 3rd time, with initial point (10) clockwise direction to terminal (11) be that the 4th forward is amounted to, with initial point (11) counterclockwise to terminal (12) be that the 4th is oppositely amounted to, with initial point (12) clockwise direction to terminal (13) be that the 5th forward is amounted to, with initial point (13) counterclockwise to terminal (14) be that the 5th is oppositely amounted to, with initial point (14) counterclockwise to terminal (15) be the 2nd reverse non-closed rectangular spiral shell around, above structure is connected and forms a unit radiation conduction band, is initial point with the 2nd reverse non-closed rectangular spiral shell around terminal point (15), with (16), (17), (18), (19) add top load for what the radiation conduction band of terminal point was formed, make on the current wave antinode and move, a unit radiation conduction band CURRENT DISTRIBUTION is more even.It is isometric with the resonant slot of 1/2 wavelength around the slit of back formation to amount to spiral shell, and promptly slit resonance is in 1/2 wavelength.
