Abstract

The invention discloses a dual-polarization microstrip patch oscillator module, which comprises a dual-polarization feed connection cable, a feed PCB substrate, two transmission cables and an oscillator support, wherein a reflecting plate is attached to one side surface of the oscillator support; four feed sheets are distributed on the oscillator support at intervals; one end of the feed sheet sequentially passes through the oscillator support, the reflecting plate and the feed PCB substrate and is in coupling connection with metal probes arranged at two ends of the dual-polarization feed connection cable; one side, far away from the oscillator support, of each feed sheet is coated with an insulation sheet; an oscillator sheet is supported on the insulation sheet; at least two bulges are arranged on the oscillator support; a parasitic patch is supported on the bulge; and an air dielectric layer is formed between the parasitic patch and the oscillator sheet for conducting signals. Air is adopted as a dielectric basic material, through a mode of attaching one parasitic patch above a main patch and designing the metal probes for coupled feed, the problem of narrow impedance bandwidthof a microstrip, in particular, a dual-polarization microstrip can be solved.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to an antenna dipole. Background technique [0002] Microstrip patch antenna is a basic and important type of antenna. Different from the half-wave vibrator, the microstrip patch antenna relies on the electric field between its two side edges and the floor below to radiate, which is essentially a two-element slot array. Unlike the former, where the height of the patch from the ground must be close to a quarter wavelength, it can be much smaller than the operating wavelength, so it has the natural advantage of low profile. In addition, the microstrip patch antenna also has the advantages of wide suitable frequency range, various dual polarizations, low cost, and easy production, and has been widely used in engineering fields. However, microstrip patches are typical resonant antennas with high Q and narrow bandwidth. Therefore, its scope of use is relatively narrow. [0003]...
