超宽角度圆极化天线及其相控阵研究

Study on Circularly Polarized Antenna and its Phased Array

宽角度圆极化天线及其阵列可以广泛应用于车载、机载和星载雷达系统等很多方面,用以在更宽空间范围内接收或发射电磁波。本文提出了一种宽角圆极化微带天线,并在此基础上设计了一个1×4单元的宽角度圆极化扫描直线阵列。该阵列具有结构紧凑、重量轻和宽角度范围内实现圆极化扫描等突出优点。

Wide-angle circularly polarized antenna and its array can be applied extensively to vehicle,aircraft and airborne radar systems.It is used to receive or transmit electromagnetic wave in large space range.This paper presents a wide-angle circular polarized microstrip antenna element,and a 1×4 element linear array is designed by the elements.The array has some advantages,such as,compact size,light weight and wide-angle scanning with circular polarization radiation characteristics.
