Abstract

The present invention discloses an aperture coupled feeding broadband patch antenna with dual-polarization performance. The aperture coupled feeding broadband patch antenna comprises a radiation layer, an aperture coupling layer and a feeding layer; the radiation layer is fitted on the aperture coupling layer; the feeding layer is fitted beneath the aperture coupling layer; the upper surface of the radiation layer is provided with a circular radiation patch for widening antenna bandwidth; the upper surface of the aperture coupling layer is provided with an annular coupling patch; a copper-plated metal surface is laid on the upper surface of the feeding layer; a first feeding slot, a second feeding slot and an isolation slot are formed in the copper-plated metal surface through etching; and the lower surface of the feeding layer is provided with a first feeder line and a second feeder line which are perpendicular to each other, the joint of the length edges of the first feeder line and the second feeder line is provided with a first port, the joint of the width edges of the first feeder line and the second feeder line is provided with a second port, and therefore, the dual-polarization performance of the antenna can be realized. According to the antenna of the invention, the isolation slot of which the tilt angel is 45 degrees is formed in the copper-plated metal surface of the feeding layer, and therefore, the isolation degree of the antenna is improved.

Description

technical field [0001] The invention relates to the technical field of radio-frequency microwave communication, in particular to a broadband patch antenna with dual-polarization performance and aperture coupling feed. Background technique [0002] In recent years, with the shortage of spectrum resources and the continuous increase of communication capacity requirements, dual-polarization and high-bandwidth antennas have become a research hotspot. Improving antenna isolation has become a common problem in many radio system antennas. For the existing multi-layer feed patch antenna, although the dual-polarization performance can be achieved by using two orthogonally placed feed structures, and the isolation is high, the size of the antenna itself is large, which is not conducive to the integration of the RF front-end . Contents of the invention [0003] The main purpose of the present invention is to provide an aperture coupled feed broadband patch antenna with dual polariza...
