摘要
采用数值仿真技术CST，研究了一款全向吸顶天线的电磁特性，包括方向图和驻波比等。优化后的天线能够在双频带806~960 MHz和1710~2500 MHz上有效工作，回波损耗小于-10 dB，最大增益为3.5 dB。制作了吸顶天线的实验模型，利用网络矢量分析仪等设备对天线进行测量，其与仿真结果对比具有很好的一致性，并针对不同几何参数对吸顶天线物理性能的影响进行了多方面的分析。
The electromagnetic properties（including radiation patterns and VSWR）of an omnidirectional ceilingmounted antenna are studied by means of the numerical simulation techniques CST. The optimized antenna can be effectively worked in dual band 806~960 MHz and 1 710~2 500 MHz. The antenna′s return loss is less than -10 dB and the maximum gain is about 3.5 dB. The experimental model of the ceilingmounted antenna was constructed and measured with the network vector analyzer. The measured result is consist with the simulation result. The influence of different geometric parameters on physical properties of the ceilingmounted antenna is also analyzed in this paper.
