Center-feed comprised of E to H-plane cross-junctions in an alternating-phase fed single-layer slotted waveguide array

This paper demonstrates the reflection suppression over a wideband of the feed waveguide which uses E-to-H-plane cross-junctions in the alternating-phase fed single-layer waveguide array. The FEM analysis is conducted using HFSS for each component as well as the full structure of the array, which has more than 30dBi gain.
