摘　　要：设计了一种基于端部加载技术的双套筒宽带全向天线,提出了一种新型的端部加载形式和特殊的双套筒结构。实际加工出来的天线工作频段为57~103MHz,在此频率范围内天线的驻波比系数VSWR<1.5(即S11<-13.98d B),天线的相对带宽为57.5%,阻抗带宽为1.81∶1。仿真结果和实际加工的天线测试结果吻合良好,结果还表明该天线在所设定的频率范围内的增益均大于2d B,且具有水平全向的方向图。This paper proposed a dual-sleeve broadband omnidirectional antenna based on end-loaded technology,the antenna presents a new type of end-load and the special dual-sleeve structure. The working frequency of the dual-sleeve broadband antenna based on end-loaded technology ranges from 57 MHz to 103 MHz,where the voltage standing wave ratio( VSWR) is less than 1. 5( which means the S11<- 13. 98 d B),the antenna's relative bandwidth is 57. 5% and the impedance bandwidth is 1. 81∶ 1. Simulation results agree well with the test results,the results also show that the antenna has a gain of more than 2d B in the setting frequency range and is omnidirectional in the H plane.
