摘要：
This article presents the relation between the cross-polar signal radiated by a dual feed patch antenna and the mutual coupling existing between the antenna feeds. The theoretical analysis is based on the S-parameters of the antenna element, providing a clear understanding of the physical relation between cross-polar level and coupling. Analytical expressions are given for the radiation pattern computation, including the cross-polar level and the effect of higher order modes on the pattern. Finally, the results of the study are illustrated with measured patterns. (C) 2000 John Wiley & Sons, Inc.
