IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.An efficient and broad‐band reflective microstrip polariser converter is proposed that converts linear polarization plane waves to circular polarization ones. It is experimentally shown that the designed device converts the LP plane‐waves to a CP one within 7.2∼12.6 GHz with 3‐dB AR bandwidth = 54.5%.

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.This paper presents a broadband 1‐bit reconfigurable transmitarray operating at 11.7 GHz, using interdigital structures to achieve a 23.1% 3‐dB transmission‐loss bandwidth without requiring an air gap. An EM‐acquired CRCS‐based link gain model is developed to evaluate the radiation gain, scattering characteristics and gain‐frequency response of the RTA.
