摘　　要：对于X波段垂直半全向天线,用传统的振子型天线实现较为困难,分析了一种用两片矩形微带串馈单元组合而成的阵列天线的阻抗和辐射特性,通过优化设计两单元天线的夹角和间距,实现了H面180°的宽波束设计,且在波束范围内的电平变化小于3dB,垂直方向3个单元串馈后得到天线的增益达10dBi。天线结构简单,性能良好,实际的实验结果和理论计算吻合较好。The design of vertical polarized half-omnidirectional antenna is very difficult,The 180° beam width was achieved by comhinafing two serial feed microstrip antennas, with simple construction and good performance, By optimizing the angle between two microstrip units, the level change of 180~ beam-width is less than 3dB.The gain arrives at 10dBi by arranging three rectangle microstrip dements of each unit.And the design concept and theoretic analysis for the rectangle microstrip antenna is discussed, The results of Computer Aided Design and test are identical,
