In this article, a new type of EBG structure known as frequency selective surface (FSS) with reconfigurable capability is investigated. The operating frequency of the FSS structure is in the Cband and in the frequency range of 4GHz to 8GHz, which at the central frequency of 4.75GHz, provides a bandwidth of about 1 GHz when the state of the diode is on. n fact, this structure is supposed to be used as a type of electromagnetic coating filter for space payload in the nextgeneration satellites.
