Abstract :
This work has studied and successfully demonstrated the ability of patch-array covers placed over PAF feeds comprising waveguide elements for achieving improved coupling and aperture efficiencies of singly-steered as well as multiple-overlapping beams, as compared to those of uncovered PAF feeds. Future work would be to include dielectric losses into the studies. Preliminary results are expected to be presented at the conference.
