Frequency Selective Surfaces (FSSs) are used widely as electrical filters in Microwave Engineering. In recent years frequency selective surface is also used as a filter in the wireless communication system. The subject of FSS is widely researched on for its uses in the areas of microwaves and optics. It was used as cassegrainanian sub reflectors in parabolic dish antenna in early days. The analyzed design of a broadband and compact frequency selective surface has been proposed here. The effects of introduction of different types of slots are studied and their simulated results are presented. This paper proposes an FSS with maximum 10 dB percentage bandwidth of 80.2% and compactness of 71.36% the simulations are done by MOM (Method Of Moment) based Ansoft Designer Software.
