Large multibeam lens antennas for EHF SATCOM

The authors discuss a practical design for a 265-port multiple-beam antenna (MBA) for EHF military satellite communication (MILSATCOM). A constrained beamforming network (BFN) with several hundred feeds and seven port feed clusters is for the intended applications in terms of performance, complexity, weight, and power consumption, is established. The design of the dielectric lens is examined. The performance of the MBA is analyzed.<
