摘　　要：实验研究了一类采用组合复用、双端馈电和套筒结构匹配等技术设计的用于船用短波超短波通信的小型宽带天线,详述了各物理结构参数对天线性能的影响。据此设计的天线在超过5个倍频程的带宽范围内,电压驻波比(VSWR)基本低于2.5,而尺寸远小于相同用途的传统盘锥、discage等天线。A kind of small sized HF or VHF/UHF broadband antenna for shipboard communication is designed through experimental studies. The antenna integrates the techniques of construction combination, dual feed and matching with sleeves. The effects of various physical parameters on the antenna＇s performance were described in detail. In a bandwidth greater than 5 octaves, the antenna＇s voltage standing wave ratio（VSWR） is under 2. 5, and its dimensions are much smaller than those of the traditional discone and discage antennas.
