A Compact Wide-Band Corrugated Horn For Satellite Communicatio

With the increasing demand for telecommunications services in recent years, in order to minimize the number of antennas on spacecraft, this paper proposed a wide-band compact corrugated horn feed antenna for Broadcast Satellite Services (BSS) and Fixed Satellite Services (FSS). Simulation is done to verify the performances of the design. The simulation results indicate that the horn antenna can cover the 10.7GHz-21.2GHz frequency band with return loss less than -28 dB and the antenna has good pattern symmetry in both E-plane and H-plane with phase center stability. The proposed corrugated horn feed antenna has wide application prospects in the field of satellite communication.
