Wideband Design of 2×2-element Dielectric-Filled Waveguide Slot Subarray for 350-GHz band
This paper presents a wideband design of a 2×2-element dielectric-filled waveguide slot subarray for 350-GHz band. The subarray is fed by a corporate feed circuit and composed of a cavity and slots. The subarray is analyzed by hybrid method of moments and finite element method and optimized by genetic algorithm. The optimized subarray shows 22% reflection bandwidth where reflection is below -14dB. The solid walls of the designed antenna are going to be replaced with post walls.
