摘　　要：将套筒单极子天线用于应急通信的V/U频段,提出了一个无地板的套筒天线设计,用An-soft HFSS软件研究该天线的多频带特性和辐射特性,并从工程角度优化了该天线的参数,套筒和同轴电缆均为标准尺寸,便于批量生产。仿真结果表明其在V/U双段能够满足所需的驻波比带宽,并且具有很好的辐射特性。VSWR小于2的频率范围是V段:127MHz-149MHz,带宽22MHz;U段:417 MHz-450MHz,带宽33MHz。取消地板以后,该天线横向尺寸大为减小,便于车载和移动使用。The application of sleeve monopole antenna to emergency communications V/U - band brought about a no -ground sleeve antenna instance. The Ansoft HFSS software was utilized to analyze the antenna＇ s muhiband and radioactive properties, which optimized the parameters of the antenna. The results indicated that the design could meet the required VSWR bandwidth at the V/U dual -band and exerted excellent radiation characteristics. The frequency range is at V/U band when VSWR is less than 2： V band with 127 -149 MHz and a bandwidth of 22 MHz; U band with 417 -450 MHz a bandwidth of 33 MHz. After the ground is removed, the lateral dimension of the antenna is greatly reduced, which is convenient for vehicle loading and mobile use.
