A novel bi‐functional ground plane is presented based on frequency selective surface (FSS) and switchable PIN diodes. The proposed FSS can not only be used as a conventional ground plane but it can also be used for spatial filtering purpose. Moreover, the structure is reconfigurable, which means it does not suffer from post fabrication design inflexibilities and can be tuned into any of its two modes of operation by simply changing the bias voltage of the PIN diodes. Unlike the traditional FSSs where transmission band remains no longer under the user's control after fabrication of the structure, the authors have demonstrated here the full control over transmission band of the FSS with the help of a PIN diode and thereby providing two modes of operation of the proposed FSS, i.e. as a spatial filter or as a ground plane.
