A 2-D Circularly Polarized Fixed-Frequency Beam-Scanning Leakywave Antenna for Millimeter-Wave Satellite Communications

A novel 2-D circularly polarized (CP) fixed-frequency beam-scanning leakywave antenna (LWA) is developed. The entire 2-D LWA comprises 16 groove gap waveguides (GGWs), a pair of 1:16 power dividers, and an array of 16\times 24 reconfigurable units. Each unit depends on a corner-cut patch to realiz...
