Design of a Ku Band Corrugated Conical Feed Network For Parabolic Antennas

This paper describes the design and simulation of a wide band corrugated conical horn feed for satellite and very small aperture terminal applications dedicated to parabolic reflectors. The design was performed using CST software. The proposed design operates in the frequency range of 12 to 14.25 GHz (Ka band) such as 12 GHz to 13 GHz for the uplink and for the down link from 13.25 GHz to 14.25 GHz. The horn feed is linearly polarized due to the feeding of a rectangular waveguide with TE10 mode. Simulation results show good Ku-band radiation characteristics including S-parameter.
