This booklet specializes in functionality enhancement of revealed antennas utilizing frequency selective surfaces (FSS) expertise. The growing to be call for of stealth know-how in strategic parts calls for high-performance low-RCS (radar go part) antennas. Such requisites might be complete by means of incorporating FSS into the antenna constitution both in its floor aircraft or because the superstrate, end result of the clear out features of FSS constitution. In view of this, a unique method in keeping with FSS expertise is gifted during this booklet to reinforce the functionality of published antennas together with out-of-band structural RCS relief. during this activity, the EM layout of microstrip patch antennas (MPA) loaded with FSS-based (i) excessive impedance floor (HIS) floor aircraft, and (ii) the superstrates are mentioned intimately. The EM research of proposed FSS-based antenna constructions were conducted utilizing transmission line analogy, together with the reciprocity theorem. additional, quite a few varieties of novel FSS constructions are thought of in designing the HIS floor aircraft and superstrate for boosting the MPA bandwidth and directivity. The EM layout and function analyses of FSS-based antennas are defined the following with the suitable expressions and illustrations.
