摘要
设计了一种工作在L波段(中心频率为1.6GHz)的圆极化微带天线,此天线在很宽的波束范围内实现了良好的圆极化特性(±60°角度范围内,圆极化轴比AR<3dB),天线采用传统的同轴线背馈的馈电方式,整体结构简单,制作成本低,并且实现了天线的低剖面性,具有广泛的应用价值。
We have designed a circular polarized microstrip antenna which works on L-band（center frequency is 1.6 GHz） frequency.The antenna achieves a wide beam range and good circular polarization characteristics in the wide main beam range（± 60 ° angle range,axial ratio AR3 dB）.The antenna is fed by coaxial back feeding method.The structure of the antenna is simple and the production cost is low.The antenna also achieves a low profile and has very broad application.
