Geometric Phase Metasurface for Lens Antenna System With High Polarisation Purity and Efficiency
IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.This work presents a millimetre‐wave antenna–metalens system based on the Pancharatnam–Berry phase principle, operating efficiently from 82 to 95 GHz. The system achieves high directivity (up to 34.7 dB), excellent polarisation purity (AR < 2 dB) and aperture efficiency exceeding 30%. The same metalens is also characterised at 75 and 105 GHz, where the
