中文摘要：

在电小尺寸锥台上,设计并实现了一款工作于全球定位系统（GPS）L1频点和北斗卫星导航系统B1频点的锥台共形水平全向圆极化微带天线阵。采用高频结构仿真（HFSS）软件进行仿真,优化共形天线带宽及其圆极化性能。加工了实物天线阵样机,测试结果表明,该天线阵在（1.32-2.0）GHz频段内驻波比≤2,在GPS L1频点和北斗B1频点处,水平全向增益最大值分别为-0.7dB和-0.9dB,增益不圆度小于2.1dB。实测结果证明,该天线具有良好的水平全向圆极化辐射性能,满足工程需要。

英文摘要：

A conical conformal circular polarized （CP） antenna array on an electrically-small sized cone is presented for the GPS LI frequency （ 1.575 GHz ） and BeiDou B1 frequency （1. 562 GHz） to realize omni-radiation in horizontal direction. Simulation results of standing wave ratio and radiation pat terns are presented by using high frequency structure simulator （HFSS） . The measured results show th at voltage standing wave ratio（VSWR） is less than 2 in the band of 1. 32 GHz-2. 0 GHz, the maximum CP gain of the horizontal direction is -0. 7 in LI frequency point and -0. 9 dB in B1 frequency p oint ,and the out of roundness of the radiation pat tern is less than 3. 5 dB. It shows the antenna has good CP omni-radiation performance in horizontal direction, which can meet the demand of engineering use.
