本文主要介绍窄边缝隙波导阵列天线的设计方法,最重要的是确定所需孔径分布(它决定副瓣电平)的缝隙电导。然后由实验得到缝隙的实际参数。为了验证设计方法,在X波段加工了70个缝隙的波导阵列,同时设计了一个二维波导平板阵,作了较全面的试验,获得了比较满意的结果。 (一)缝隙电导 在缝隙波导阵列中,第i个缝隙的电导是
This article focuses on the design of narrow-edge slotted waveguide array antennas. The most important thing is to determine the gap conductance for the desired aperture distribution that determines the sidelobe level. Then the actual parameters of the gap obtained by the experiment. In order to validate the design method, a waveguide array of 70 slots was fabricated in the X-band and a two-dimensional waveguide array was designed at the same time. A more comprehensive experiment was conducted and satisfactory results were obtained. (A) Slot Conductance In the slot waveguide array, the conductance of the i-th slot is
