摘要

本文设计了一种新颖的具有加减信道的低旁瓣微带天线阵.在研究低旁瓣角馈方形微带贴片天线的基础上

设计了一个3dB定向耦合器作为馈电部分

从不同的输入端口输入信号

分别实现方向图加减的功能.这种天线能够同时获得其视野内所有障碍物的范围和角度信息

不需要使用扫描天线或转换天线.使用ANSOFT公司的Serenade和Ensemble两种软件进行了设计、仿真和优化.实验结果与仿真基本一致

可见

这种天线完全可以满足设计要求.

Abstract

A novel low-sidelobe microstrip antenna with sum and delta channels is designed.The low sidelobe corner-fed printed square patch antenna is studied.A hybrid ring circuit located on the center of the antenna performs the addition and subtraction of the signals from different ports.The antenna is capable of acquiring the range and angular information of all obstacles in its field-of-view simultaneously without using a scanning or switching antenna.Design

simulation and optimization are carried out using softwares of Ansoft Serenade and Ensemble.The results of experiment is similar to the results of simulation.It is obvious that this kind of antenna is able to meet the design target.
