双波束同步扫描相控阵天线的设计

一种双波束同步扫描相控阵天线的设计

内容简介：详细介绍了一个具有双波束同步扫描功能相控阵天线的工作原理、设计方法及其实测结果,该天线为平面相控阵形式,工作频率为150～260 MHz,水平极化,增益大于28 dBi,同时具有方位低副瓣和俯仰余割赋形的特点。

Abstract：A dual-beam synchro-scanning phased array with the low-sidelobe feature and a cosecant shaped pattern, which works from 150 MHz to 260 MHz,is introduced. This planar phased array is hori- zontal polarized, and its gain is greater than 28 dBi. The working principle and design methods are de- scribed, and a pratical measured results are presented in the end.
