A Frequency-Selective Surface (FSS) is any thin, repetitive metal surface designed to reflect, transmit, or absorb electromagnetic radiation according on the frequency of the wave. The entering plane wave will either be transmitted (passband) or reflected back (stopband) depending on the characteristics of the unit cell. This happens when the frequency of an electromagnetic (EM) wave coincides with the resonance frequency of the FSS components. As a result, an FSS is a spatial filter capable of allowing or inhibiting EM waves of a certain frequency range in free space. FSSs have now been widely investigated, and great progress is being made in the field of their design and implementation for a wide range of practical applications, from microwave to optical frequencies. The Frequency Selective Surface attached to the new center-fed circular patch antenna is presented. A wide band from 5 GHz to 6.2 GHz is achieved with a monopole-like radiation pattern. According to simulation results of the proposed antenna structure, it can be applied in ISM band applications, wireless audio and video systems and other wireless communications at 5.8 GHz. It has a simulated maximum gain of 5.36 dBi and a bandwidth of 31.1 %. Throughout the operational band, the omnidirectional radiation pattern is fairly constant. The overall dimensions of the antenna are 27.34  27.34 mm2 including FSS structure thus makes a compactable wideband system at 5.8 GHz. A circular patch antenna with diamond slot at center initialize first resonance at 5.8 GHz with a dimension of 20  20 mm2 and performance parameter is further improved by appending FSS Structure.
