Curvature effect on the mutual coupling of circular microstrip antennas

Abstract

f i e mutual coupling between cylindrical-circular microstrip antennas is studied by applying the cauity-model analysis and the reaction theorem. fipressions of the mutual coupling coejjicients for the E-plane and H-plane coupling cases are presented. Theoretical results are calculated, and the curuature effects on the mutual coupling are discussed. 0 1995 Microwave and Optical Technology Letters, l O / l , 39-41 0 1995 John Wiley & Sons, Inc.
