Abstract
This work proposes a phase-shifting unit cell for a reconfigurable intelligent surface capable of exhibiting 7 discrete reflection phase shifts at 3.75 GHz. Sets of PIN diode-loaded unit cells are addressed column-wise to realise azimuthal electromagnetic transformation capabilities with a simple, vialess feeding mechanism. Simulated results utilising manufacturer’s component data suggest a desirable average reflection loss of 1 dB. A particle swarm optimisation algorithm is employed to realise reflection phase uniformity. Oblique incidence performance is investigated, revealing desirable phase shift resolution versus incidence angle beyond 40° for TM-polarised waves.
