- In this paper, mode transitions inside the waveguides with step discontinuities are studied. These transitions are applied to design the corrugated horn antenna directly connected with band pass filter (BPF) in millimeter wave regime. The used rectangular waveguide at the input port is a WR-22 standard waveguide for the frequencies from 40.5GHz to 43.5GHz. The RF system used for transmitter and receiver requires wide beam width and wide bandwidth characteristics for coverage and return loss, respectively. Also the antenna needs the high front-to-ratio in radiation pattern.
