Abstract

Reactive impedance surface refers to an array of periodic structures that are built over a dielectric substrate (RIS). RIS is a layer that was produced artificially to improve patch antenna performance. Although there is a wealth of literature in the field of RIS, the theoretical underpinnings of how the RIS improves patch antenna performance remain unclear. The purpose of this paper is to explain theoretical ideas and analyze how the RIS improves performance. also includes an evolution of RIS progression.
