| 摘 要： | 为了避开电磁干扰源，对全向锥形天线做了改进，设计了一种用于无线通信的宽带抗干扰定向单锥天线。首次应用加载短路枝节来实现单锥天线H面的定向性，与传统实现定向性的给天线组阵或添加反射器等增加天线尺寸的方法不同，该方法不会增大天线的尺寸，同时H面又具有很宽的3dB波瓣宽度。该定向单锥天线在1.7GHz?6.0GHz的频带内回波损耗小于-10dB,仿真和实测结果吻合良好，在较宽的频带内具有满意的阻抗特性和方向图特性。

| Abstract: | A broadband anti-interference directional mono-cone antenna is designed in order to avoid electromagnetic interference sources in wireless communication. Omni-directional cone antenna is made improvement by adding shorted stub to realize mono-cone antenna directionality in H-plane. New method is different from general methods such as using array antenna or adding reflector, which will not increase the size of the antenna. The 3dB beamwidth in H-plane is wide and the return loss is less than -10dB within the frequency range of 1.7GHz ~ 6.0GHz of this antenna. The acceptable agreement of measured and simulated results shows that this kind of antenna has perfect input impedance and pattern properties． |
