【摘要】 结合经验公式和仿真软件,设计出了一种用于海事卫星通信系统的圆极化微带阵列天线。天线采用双层结构,介质基片选择泡沫材料,并采用正方形切角的方式实现圆极化。利用高频电磁仿真软件AnsoftHFSS对该阵列天线进行了仿真优化。仿真结果表明,该天线具有良好的宽频带特性,天线在整个海事卫星通信工作频带内驻波比小于1.5,同时天线的最大增益达到13.5dB。更多还原

【Abstract】 A circularly polarized microstrip array antenna for maritime satelte communication was designed by combining the experimental formulae and the simulation software. A dual-layer structure was proposed, and the foam was chosen as the medium substrate, the antenna is circularly-polarized by corner-truncated square patch. The Antenna designed was simulated and optimized by HFSS. The simulation results show that this antenna has good wideband characteristic. The impedance bandwith for VSWR<1.5 in the whole INMARSAT(International Maritime Satellite Organization) communication work bands, and the maximal gain 13.5dB is also achieved.更多还原
