Abstract: We present an equivalent unit cell waveguide approach (WGA) to designing a multilayer microstrip reflectarray of variable size patches. A normal incidence of a plane wave on an infinite ...

Abstract: We propose a multilayer unit cell consisting of Minkowski fractal-shaped reflector with aperture coupled phasing stubs to obtain a broad phase range for reflectarray antenna with smaller ...

This paper presents a study on Active Frenquency Selective Surface (AFSS) for applications in modern wireless communication systems. Initially, an FSS with an element inspired by convoluted metallic ...
