Abstract

The invention relates to a miniaturized dual-polarization broadband Fabry-Perot resonant cavity antenna. The antenna comprises a square patch antenna, a feed network arranged below the square patch antenna, and a reflection cover plate arranged above the square patch antenna. The feed network comprises: a first dielectric substrate, wherein a Y-shaped first microstrip line is formed on the upper surface of the first dielectric substrate through copper cladding; a second dielectric substrate, wherein a Y-shaped second microstrip line is formed on the lower surface of the second dielectric substrate through copper cladding, and the second microstrip line is perpendicular to the first microstrip line; and a grounding plate, which is arranged between the first dielectric substrate and the second dielectric substrate. The square patch antenna is a third dielectric substrate with one side coated with copper; and the reflection cover plate is a single-layer fourth dielectric substrate with double surfaces coated with copper. The antenna has the characteristics of dual polarization, high gain, wide frequency band and miniaturization.

Description

technical field [0001] The invention relates to a Fabry-Pérot (FP) resonant cavity antenna, in particular to a miniaturized dual-polarized broadband Fabry-Pérot resonant cavity antenna, belonging to a communication resonant cavity Antenna technology field. Background technique [0002] At present, with the rapid development of wireless communication technology, the requirements for directional antennas are becoming more and more stringent, especially in the microwave and millimeter wave frequency bands. The traditional technologies for achieving high antenna gain include: loaded reflectors, dielectric prisms, waveguide horns, and microstrip antenna arrays; however, these structures are limited by high cost and complex design. In recent decades, the application of electromagnetic bandgap (Electromagnetic Band-Gap, EBG) in suppressing electromagnetic waves has attracted widespread attention. One of the important applications is the high-gain Fabry-Perot (Fabry-Pérot, FP ) re...
