Summary:
This paper presents a switchable frequency selective surface (FSS) based on a modified Jerusalem-cross (JC) unit cell with extended top loading. Various combinations of switches are considered to make it switchable and the corresponding FSS behavior is analyzed. It is noted that the pass band(s) and stop band can be achieved by turning switches ON or OFF appropriately. For example, as a band pass FSS, it can provide single wide-band operation covering a bandwidth of 1.5GHz (2.97?4.47 GHz). In another mode, two narrower pass bands, one around 2.4GHz and other around 5.4GHz, can be achieved. Third mode allows a very wide stop band. The proposed FSS unit cell has been designed for fabrication on FR-4 to provide an inexpensive reconfigurable solution.
