K/Ka Band High Gain Antenna with Shaped Beam for HEO Satellite

A K/Ka band dual band high gain horn antenna with shaped beam for HEO satellite has been developed for K/Ka band TT&C. The horn geometry uses both horizontal and vertical corrugations liner control profile with dual-depth vertical corrugations. The geometry of the horn is optimized to have maximum Edge of Coverage (EoC) within ±16° at all frequencies of interest. The measured results show that the EoC gain is more than 12.9 dBi and 13.1 dBi in EoC region at both K and Ka band respectively. The antenna has broad application prospects in HEO satellite.
