Dual-band Multi-Polarization Metallic Cavity Antenna Design for Satellite Communications
2022 16th European Conference on Antennas and Propagation (EuCAP)（2022）
Abstract
A highly reconfigurable dual band cavity structure for satellite communications at K/Ka band is proposed. The key of the presented structure lies on a compact dual stacked cavity system. By modifying the radius of each cavity and the dimensions of the feeding slot, both cavities have been matched at the center frequency of their respective band. Correctly enabling and phasing each input port allow...
