A Lightweight and Portable Design of Antenna Feed for 1.8M S/X-band Auto-Tracking Ground Station
A compact S/X-band dual circularly polarized auto-tracking antenna feed for 1.8m auto-tracking ground station is presented. It is designed to reduce the weight of the antenna system to make it more portable. The feed consists of X-band dielectric rod horn and S-band microstrip antenna array installed at the periphery of the horn. A double-layer sum-and-difference microstrip network is designed to connect to a microstrip array for communication and auto-tracking in the S-band.The X-band feed is designed with a dielectric rod horn structure, and the shape of the dielectric rod is convenient to adjust the beamwidth of the X-band and S-band. The results show that the antenna gain of the 1.8m reflector is larger than 28.6dBi and 40.1dBi in the S/X-band, the axial ratio is less than 0.7dB, and the null-depth of the difference beam in the S band is less than -37dB.
