## Abstract A dual band frequency selective surface (FSS) based on circular apertureβcoupled patches is presented. The technique is based on using two same structures with different sizes. A special topology is proposed to arrange the two different sizes structures. Each structure is composed of tw

## Abstract In this article, the spectral domain method of moment is utilized to analyze frequency selective surface with RWG basis functions for arbitrarily shaped metal geometry. The Fourier transform of the RWG basis function can be expressed in the analytical form and the fast convergence chara
## Abstract In this letter, a ringβshaped frequency selective surface (FSS) superstrate is designed to enhance the directivity of a circularly polarized patch antenna by reducing the sidelobe levels. Based on the unit cell simulation, several important parameters that characterize the ringβshaped F
