通过对Stevenson缝隙偏移位置公式进行修正，设计了一个工作于V波段的波导缝隙阵列天线。仿真结果表明，利用修正公式，可快速、准确地设计出高性能低副瓣波导缝隙阵列天线。天线增益17dB，H面主波束偏转60。副瓣电平小于一32dB。

A slotted waveguide antenna operating in V-band is designed using a modified Stevenson formula to determine the offset of the waveguide slots. The numerical simulation results show that a waveguide antenna of high performance can be designed by the modified formula quickly and accurately. The antenna exhibits an excellent performance with gain 17 dB, beam tilt angle 60~, and low sidelobes levels are less than --32 dB.
