摘要
提出了一种适用于跑道异物(Foreign Object Debris, FOD)检测系统的V波段波导缝隙阵列天线。所提出的阵列天线工作频带为74~79 GHz,阵面包含2 048个单元。天线采用多模波导缝隙阵列天线形式,并设计了波导功分网络,具有高增益、低剖面等优良特点。天线整体结构厚度10 mm以内,辐射效率50%以上。天线的实测结果表明,理论结果和测试结果吻合,具有较高的工程实用性。
In this paper,a V-band waveguide slots array antenna suitable for FOD detection system is presented.The operation frequency range of the proposed array antenna is 74~79 GHz and the array contains 2048 elements.The proposed antenna has excellent characteristics such as high gain and low profile by using the form of a multi-mode waveguide slot array antenna and a waveguide power division network.The thickness of the antenna is within 10 mm and the radiation efficiency is above 50%.The experimental results show that the measured and simulated results are agreed well with each other,so it is of good practical engineering application.
