Abstract
This paper presents a numerical simulation of a binary chessboard-coding artifact in the designs of wave objects for upcoming smart communication in a centimeter-wave range. The binary-coding artificial structures can be composed of a mixture of two types of unit cells with the digital states of “0” and “1” elements in a two-dimensional (2D) structure. The binary characters are essential to a unity magnitude of a reflection type with the dependence of an opposite phase response at 0 and 180. The proposed binary coding configuration relies on utilizing an artificial magnetic conductor (AMC) which is formed by a patch-based array over a perfect ground surface with a dielectric slab. The scattering characteristic is illustrated at the operating frequency of 10 GHz. The antenna device as a wave object is designed using the binary chessboard-coding artifact with a function of wave radiation. With a simulation technique, numerical analysis provides an understanding of the electromagnetic (EM) effect of binary-coding unit cells and antenna designs. The results of a computational process can identify the potential properties of the chessboard-coding artifact.
