✦ Synopsis

The coupling matrix is a standard way to represent the mutual-coupling effect between elements in an antenna array. In this paper, two commonly used approaches to determine the coupling matrix are examined, and their limitations are discussed. The coupling matrix obtained from the minimum mean-square error matching of the acti¨e and stand-alone element patterns is shown to be more effecti¨e than the mutual-impedance approach. The coupling-matrix model is also extended for more complex antenna arrays, and an example is pro¨ided to illustrate the effecti¨eness of the extended model.

## Abstract In this paper, a method to evaluate array patterns is presented. This method considers all the mutual‐coupling effects, and assumes that the field of an element is the sum of two distinct modes: an antenna mode and a diffraction mode. Good results are obtained for a finite linear‐dipole

The element-pattern correlation explains the existence of correlation between the signals received by different antenna elements in an antenna array. Usually the array losses are ignored. A more realistic model for pattern correlation in a two-element array including losses is presented and discusse

## Abstract The active element patterns of antenna arrays are strongly affected by the interaction between the elements and the mounting platform. In this article a combined model is proposed to model the array response, including both mutual coupling and the platform effect. The mutual coupling is
