Modelling of the Slotted Rectangular Waveguide Array Antennas

Abstract

In this study, the slotted rectangular waveguide array (SRWA) antennas' lengths and widths of slots, and the distances between the slots has been changed to observe the radiation properties of the structure. Return loss and radiation pattern graphics of the designs has been obtained using HFSS simulation program. Deviation in resonance frequency and differences in resonance frequency return loss values has been examined on the obtained simulation results.
