| 摘 要： | 介绍了一种抗干扰矩形波导缝隙阵列天线的设计方法，仿真、设计并加工了一款基于T型谐振器的四缝隙矩形波导缝隙阵列天线. 通过在矩形波导下壁引入周期性的T型谐振器，有效提升了天线的抗干扰能力. 测试结果表明，该天线的?10 dB阻抗带宽为10.3%（5.5～6.1 GHz），增益为11.5～12.8 dBi，天线效率为72.1%～87.3%。与传统矩形波导缝隙阵列天线相比较，本文设计天线在抑制频段 7.9～9.6 GHz的抗干扰能力提升了32.2～69.3 dB，适用于多频段、多任务的无线通信、雷达系统等.

| Abstract: | An anti-interference rectangular waveguide slot array antenna is presented in this paper. The anti-interference performance of the antenna is improved by periodically loading a row of T-shaped resonators at the bottom broad wall of the rectangular waveguide. A four-slot rectangular waveguide slot array antenna based on T-shaped resonators is simulated, designed and fabricated. The measured results show that the impedance bandwidth is 10.3% (5.5?6.1 GHz) with realized gains of 11.5?12.8 dBi and antenna efficiency of 72.1%?87.3%. Compared with a traditional rectangular waveguide slot array antenna, the anti-interference ability of the proposed antenna is improved by 32.2?69.3 dB in the suppression band of 7.9?9.6 GHz, so it is suitable for multi-band and multi-task wireless communication and radar systems. |
