Frequency Scanning Fabry-Pérot Cavity Antenna with Single 2D Varying Partially Reflecting Surface
IET Microwaves, Antennas & Propagation
This study presents a frequency scanning Fabry-Pérot cavity antenna with a single 2D varying partially reflecting surface (PRS) operating from 9.4 to 10.6 GHz. A probe-fed stacked rectangular patch antenna is applied as the primary source. A PRS consisting of 9 × 9 cells, whose sizes vary with azimuth, is mounted upon the source to modulate the phase efficiently. Due to the opposite correlations between scan angle and frequency in the forward and backward regions, phase distributions in thedoi:10.1049/iet-map.2019.0884 fatcat:c65psetvbzawxgaan6lpoujvhe
