Abstract This work presents an RFSS with two discrete states, corresponding to a pass‐band or stop‐band response depending on PIN diode biasing. The RFSS behaves as an array of cross dipole elements when all diodes are in the OFF‐state and as a grid when the diodes are in the ON‐state. The cross dipole patch array has a stop‐band filter response and the grid behaves as a pass‐band filter at the design frequency of 1.6 GHz. Simulation and measurements of insertion loss are presented, demonstrating the switchable band‐pass to band‐stop response.
