Design and Realization of an X Band Monopulse Feed Antenna for Low Earth Orbit (LEO) Satellite Ground Station

In this work, design of a five-element compact dual-polarization X band monopulse feed antenna using a 7.3 m Cassegrain-type reflector for Low Earth Orbit (LEO) satellite ground station is presented. The designed antenna has reached 32 dB/K G/T value, the side lobe level of the designed antenna is at the level of −24 dB, the crosspolarization value is −35 dB, and the port isolation value is below −29 dB in the 8–8.5 GHz frequency range. The antenna efficiency of the designed antenna is measured as 79.93%.
