摘要 介绍了一种宽带宽、轴比带宽宽的卫星接收天线的设计,天线采用微带线共面馈电的微带天线形式,利用增加寄生贴片展宽天线单元的电压驻波比带宽和圆极化轴比带宽,利用旋转馈电技术扩展了天线阵列的圆极化轴比带宽。天线设计得到了实验的验证。 This paper presents a design of earth station antenna which has a wide bandwidth and a wide circular polarization bandwidth. This antenna is realized by coplanar feed microstrip antenna. The bandwidth for VSWR and bandwidth for circular polarization axial ratio of antenna array element are increased by adding a parasitic element. The bandwidth for circular polarization axial ratio of antenna is also increased by using sequential feeding technique. The design of this antenna has been validated through experiment.
