Slot waveguide is characteristic of wide frequency band and high aperture efficiency.This paper calculates the radiation slot parameters of the single-ridge waveguide slot antenna array using MATLAB software programming according to AdolfChebyshev aperture distribution method and designs an 8-slot single-ridge waveguide slot array antenna.Furthermore

it optimizes the gap parameters and simulates the bandwidth characteristics of the antenna using the three-dimensional electromagnetic simulation software HFSS.The results indicate that the size parameters of the single-ridge waveguide slot affects the bandwidth and relative to the rectangular slot waveguide

the VSWR bandwidth of the single-ridge slot is substantially broadened

which provide a valuable reference for the applications of slot ridge waveguides in communications and radar antennas.
