Designing and Studying the Characteristics of Rectangular Waveguide using HFSS

The rectangular waveguide characteristics and field distribution for various modes in rectangular waveguide when the waveguide is in the free space is computed using HFSS software. The analysis is made for different parameters. The electric and magnetic fields strengths are analysed inside a rectangular waveguide along with fundamental modal distributions. Simulation analysis is carried out for X-band and for two unique sizes i.e., breadths a=32.86mm and 22.86mm and widths b=20.16mm and 10.16mm. Characteristics profiles are analysed and the performance of rectangular waveguide is studied. Simulations are carried out for waveguide and both results of different dimensions are compared. A HFSS simulation platform for the analysis of the aperture radiation from a dielectric i.e., air filled rectangular waveguide is depicted.
