Mutual coupling between rectangular microstrip patch antennas

Abstract A comprehensive study of the mutual coupling between two rectangular microstrip patch antennas is presented. Using the cavity model, numerical results for both mutual impedance and mutual coupling parameter are given for the E‐plane, H‐plane, diagonal, and perpendicular orientations. The effects of substrate thickness, substrate permittivity, and feed positions are discussed. © 1992 John Wiley & Sons, Inc.
