This booklet makes a speciality of functionality enhancement of revealed antennas utilizing frequency selective surfaces (FSS) know-how. The growing to be call for of stealth know-how in strategic parts calls for high-performance low-RCS (radar pass part) antennas. Such necessities can be comprehensive by means of incorporating FSS into the antenna constitution both in its flooring aircraft or because the superstrate, as a result of the filter out features of FSS constitution. In view of this, a unique technique according to FSS know-how is gifted during this publication to augment the functionality of published antennas together with out-of-band structural RCS aid. during this exercise, 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 buildings were performed utilizing transmission line analogy, together with the reciprocity theorem. additional, numerous sorts 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.
