摘要

本文提出了一种±45°双极化天线，该天线主要由主辐射体、寄生贴片、馈电网络和箱形反射板组成。天线的小型化是通过在主散热器和反射板之间增加一个电介质来实现的，主散热器的尺寸为$0.257\lambda_{0}\乘以0.257\lambda_{0}$。仿真结果表明，该天线- 14dB带宽为2.42GHz~2.74GHz，增益为7.8dBi~8.3dBi，半功率波束宽度为67.2°~3.5°，轴向交极化比大于33dB， ~60°交极化比大于10dB。

A Miniaturized Dual-Polarized Patch Antenna With Low Cross Polarization

In this paper, a ±45° dual-polarized antenna is proposed, which mainly consists of a main radiator, a parasitic patch, a feed network and a box-type reflector plate. The miniaturization of the antenna is achieved by adding a dielectric between the main radiator and the reflector plate, and the size of the main radiator is $0.257\lambda_{0}\times 0.257\lambda_{0}$. The simulation results show that the antenna has the −14dB bandwidth of 2.42GHz~2.74GHz, the gain of 7.8dBi~8.3dBi, the half-power beamwidth of 67.2°~3.5°, the axial cross-polarization ratio greater than 33dB, and the ~60° cross-polarization ratio greater than 10dB.
