摘要

本文提出了一种用于雷达工作的广角波导阵列天线，并设计了一种脊状波导天线来扩大波束的转向角。与WR-90波导相比，微型化率达到48.2%。以此为基础，设计并制造了1×8阵列天线。每个天线的平均波束宽度为120°。制作了若干与光束转向角相对应的移相器，验证了测得的光束转向角与设计的光束转向角一致。因此，所设计的天线具有适合六边形阵列结构的波束导向特性。

Design of Ridge Waveguide Array Antenna for Radar

In this paper, we suggest a wide-angle waveguide array antenna for radar operation and designed a ridge waveguide antenna to enlarge the beam steering angle. A miniaturization rate of 48.2% was obtained compared to the WR-90 waveguide. Using this, a 1×8 array antenna was designed and manufactured. The average beam-width of each antenna was 120°. A number of phase shifters corresponding to the beam steering angle were fabricated, and it confirmed that the measured beam steering angle was consistent with the designed beam steering angle. Accordingly, the designed antenna has characteristics suitable for beam steering of a hexagonal array structure.
