This paper presents the theory and design of a dual-band dual-polarized high gain Resonant Cavity Antenna (RCA). RCA with slotted circular patch frequency selective surface (FSS) is used atop primary feed i.e., microstrip patch antenna at a height of ∼λ/2. The proposed structure is simulated using FEM based HFSS and 3D-EM Solver CST Studio Suite. The slot type defect is introduced in the patch FSS...
This paper presents the analysis of high gain dual polarized cavity reflex antenna (CRA) using two different geometries (i.e. square and circular) of slotted patch type frequency selective surface (FSS) superstrate. A microstrip patch antenna is used as a primary feed for both the configurations. The structures are analyzed using FEM based Ansoft HFSS and 3D-EM Solver CST Studio Suite. The results...
