This paper presents the design of a wide-band compact antenna feed for dual-band single circular polarization. The feed chain system is based on a recently proposed configuration that uses a diplexer and a bi-phase polarizer conveniently joined by a single mode waveguide. This solution leads to compact low-cost feed designs well suited for multi-beam antennas with a single feed per beam in the context of satellite communications. A new design with enhanced performance is presented with simulated results of axial ratio below 0.2 dB across 18.2-20.2 GHz and 28-30 GHz. Moreover, the impact of the finite return loss of the high efficiency horn is studied and a compensated high-performance feed is presented. | |
