Abstract: A compact wideband feed cluster with dual-polarized sum- and difference-patterns is proposed in this paper. By utilizing dual-ridged waveguide orthomode transducers (OMTs) and wideband Magic-Tees, a highly integrated feed cluster with wide operational bandwidth, dual-polarization,… read more here.
