摘　　要：将减高锥形天线与集总元件天馈网络相结合,实现了一款低轮廓大功率宽带UHF天线。该天线轮廓低、尺寸小、工作频带宽、功率容量大、结构紧凑,能够较好满足车载干扰机对天线的要求。实验测试表明,所设计的天线在800~1500 MHz频带范围内S11基本都在-13 d B以下,方向性系数达6.23 d Bi,单侧半功率波束宽度约为74.32°。该设计对于研制低轮廓大功率宽带UHF天线具有一定参考价值。The paper proposes to get height compressed cone antenna and lumped-load matching network together to form a low-profile,high power and broadband UHF antenna. The antenna has the characteristics of a low-profile,small size,broadband,high power capacity and compact structure,which can well meet the application requirements of vehicle jammer.The experiment shows that the antenna in 800 ~ 1500 MHz frequency range with S11 is basically below-13 d B,directivity is about 6. 23 d Bi and half-power beamwidth is 74. 32°,respectively. The paper has a certain reference value to develop the low-profile,high power and broadband UHF antenna.
