摘要
提出一种适用于宽带全球局域网(BGAN)地面移动终端低成本天线的设计方案。通过选用泡沫塑料和铝箔材料,采用叠层微带天线阵结构及多种展宽带宽的方法来实现天线设计,并进行了电磁仿真优化。最后对天线进行了加工试验,测试结果表明天线在整个海事卫星通信工作频带内驻波比小于1.5,增益高于14dB,3dB广角轴比大于21°。本文所设计的天线已成功应用于HNS9201移动终端。
A design scheme of low cost antenna for Broadband Global Area Network （BGAN） mobile ground terminal is presented in this paper. By chosing the material of foam and aluminum foil, employing the stacked microstrip antenna array, and adopting several techniques to enhance the bandwidth, the antenna is designed and is optimized by EM simulation. The measured results from the antenna fabricated show that in the whole INMARSAT（International Maritime Satellite Organization） communication work bands, the VSWR is less than 1.5, the gain is better than 14 dB, and wide-angle axial ratio （AR） 3 dB is more than 21°. The antenna has been successfully applied to HNS 9201 terminal.
