Abstract

The invention discloses an improved angle-feed high-isolation dual-polarization stacked microstrip antenna used in wireless communication, the antenna has the advantages of frequency bandwidth, dual polarization, high isolation and high integration of antenna and feeder. The antenna improves the isolation of its different polarization ports by offsetting the feed point of the traditional angle feed antenna and opening triangular slots on the edge of the patch, and its basic structure includes an upper dielectric plate (1) and a lower dielectric plate (2). ), plastic screws (3), upper square patch (4), lower square patch with triangular grooves (5), microstrip impedance transformation line deviated from the corners of the lower patch (6), feeding microstrip line (7). The biggest innovation of the present invention is to improve the isolation between its different polarized ports by shifting its feeding point and opening a triangular slot, so that the antenna can achieve an impedance bandwidth of 9% when the standing wave ratio is less than 1.5. In the working frequency band, the port isolation is improved to 29dB from 19dB of traditional angle feed antenna.

Description

technical field [0001] The invention belongs to the technical field of antenna engineering, and relates to a laminated microstrip antenna, in particular to an improved angle-fed high-isolation double-polarized laminated microstrip antenna which can be used in the field of wireless communication. Background technique [0002] With the development of a new generation of wireless mobile communications, the number of mobile users is increasing, and the requirements for the number and density of base station construction are higher, and it is becoming more and more difficult for various mobile operators to select sites for network construction. With the advantages of integration, miniaturization, low cost, and easy installation, micro base stations have become a research hotspot in the new generation of wireless mobile communications. The microstrip antenna has the advantages of low profile, low cost, light weight, easy processing, suitable for mass production, etc., and is very ...
