Abstract :
A reconfigurable circular polarisation selective surface (CPSS) is proposed as a first step towards the design of dual-circular polarisation reflectarray with active and independent control in both polarisations. A CPSS unit-cell is studied at 8.5 GHz. It provides a 2-bit phase resolution in reflection for the left hand circular polarisation (LHCP) and is nearly transparent in right hand circular polarisation (RHCP). The simulated characteristics are excellent over a 6.4% bandwidth.
