Single radar platform merges object detection and road surface analysis via polarimetric antennas, eliminating separate sensor hardware.
Rotated polarization planes separate object signals from wall reflections, improving detection precision.
A multi-channel split swath SAR antenna uses separated RF feed arrays to form fixed radar beams for wide ground coverage.
A microstrip antenna transceiver uses switch elements and pattern slots to generate right-handed or left-handed polarized signals via a single radiation patch.
A compact antenna structure integrates a dipole and slot element to radiate orthogonal polarizations with omnidirectional azimuth patterns.
Orthogonal slots in a single-ridge waveguide achieve circular polarization while reducing grating lobes and beam tilting.
