Coupling Modeling and Reduction Techniques of Cavity-Backed Slot Antennas: FDTD Versus Measurements
Stavros V. Georgakopoulos, Student Member, IEEE, Craig R. Birtcher, and Constantine A. Balanis, Fellow, IEEE
Abstract―Cavity-backed slot (CBS) antennas are commonly used in earth-based and space-borne applications. In this manuscript, the finite-difference time-domain (FDTD) method is used to analyze different antenna characteristics of such elements including input impedance, coupling, and radiation patterns. Emphasis is given on coupling calculations especially on different methods to reduce coupling. Specifically, coupling reduction is attempted using lossy material superstrates or ground plane discontin
