Abstract :
A novel tanh-profile corrugated feedhorn application in quasi-optical system is proposed in this paper. The simulation results of the corrugated feedhorn are carried out via CHAMP. The simulated bandwidth is from 300GHz to 350GHz and the center frequency is 324GHz. The proposed tanh-profile corrugated feedhorn application can achieve very low return loss, sidelobe and cross polarization levels around -40dB, -35.1 dB and -45dB respectively.
