A W-band Choke-Ring Encircled Focal Plane Array of Full-Metal Elements for Deep Reflector Antennas with over 50%-Efficiency High Cross-Over Beams

The presented DataSet is dedicated to a W-band (92-96 GHz) focal plane array (FPA) for 50 dBi-reflector antennas intended for the next-generation point-to-point communication links with antenna mast sway compensation. The FPA comprises seven metal waveguide elements arranged in a hexagonal lattice, ensuring the cross-over level of the corresponding reflector beams above -6 dB. The primary challenge of this design is to realize efficient illumination of the reflector for the on-axis and off-axis beams, while keeping a minimum beamforming complexity (i.e., one element per beam) and overcoming array implementation challenges associated with high frequencies. This is accomplished by (i) a high decoupling level of the FPA elements (
