摘　　要：综合几种展宽微带天线带宽的方法,设计出一种适用于海事卫星通信系统的圆极化微带天线.天线采用双层结构.介质基片选择泡沫材料.利用高频电磁仿真软件Ansoft HFSS对该微带天线进行了仿真优化.结果表明,在电压驻波比≤2时,天线的阻抗带宽达到12.8%.同时天线的最大增益达到9.3 dB.This paper presented a design of microstrip antenna for INMARSAT mobile ground terminal by adopting several techniques to broaden the bandwidth.A dual-layer structure was proposed,and the foam was chosen as the medium substrate.The antenna designed was simulated and optimized by HFSS.The re- sults show that the impedance bandwidth for VSWR≤2 reaches 12.6%,and maximal gain 9.3 dB is also achieved.
