摘　　要：本文研究了一种双层结构的宽带印刷偶极子天线,贴片分别置于介质板的两侧。利用电磁仿真软件Ansoft HFSS进行了仿真设计并进行了实验研究,计算结果与实验结果吻合良好,其驻波比小于2的带宽可以达到64%,充分显示了此天线的良好的宽频带特性。The design of the double-layer antenna consisting of three arms which are printed on opposite sides of an electrically thin dielectric substrate and connected through a parallel microstrip is presented.The antenna is simulated and designed by the electromagnetic software Ansoft HFSS.The calculated results agree well with the experimental results.The relative bandwidth of this antenna can reach 64%with the VSWR less than 2,which shows its good electric characteristics.
