Overlapped feeds to increase the edge of coverage gain in multi-beam reflector antennas (original) (raw)

The study proposes a novel approach to enhance the performance of multi-beam reflector antennas by employing a dielectric super-layer to minimize spill over losses from the reflector. By utilizing leaky wave excitations, the design aims to improve the efficiency of small feed antennas arranged in a hexagonal lattice, addressing the trade-offs between bandwidth, beam isolation, and efficiency in telecommunications applications. Prototypes of two feed arrays are developed to validate the effectiveness of this approach in optimizing edge of coverage gain, crucial for radiometric imaging systems and advanced telecommunications.
