摘　　要：设计了两种水平全向共形微带天线,采用电磁仿真软件CST MWS(CST MICROWAVE STUDIO)进行仿真,给出了天线的回波损耗和水平面方向图。天线采用了结构上对称的形式,利用微带贴片天线单向辐射的机理,实现了水平方向全向辐射。分析了天线的结构及仿真图,研究了阵列天线参数对全向性不圆度指标的影响,对于设计水平全向共形微带天线有重要的价值。Two kinds of horizontally polarized omni-directional conformal microstrip antenna are presented in this paper. The return loss and horizontally directivity of this conformal microstrip array antenna are simulated using CST MWS.First,the conformal microstrip antenna is designed by symmetrical structure,and using the single radial property of the microstrip patch antenna,the omni-radiation in horizontal direction is realized.Then,the return loss and radiation pattern are analyzed.At last, the influence of the characteristic of the omni-directional radiation is studied.The research in this paper is significant to design and application of horizontally polarized omni-directional antennas.
