Mutual‐coupling decomposition in antenna arrays

Microwave and Optical Technology Letters, 2004
AbstractIn 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 array. © 2004 Wiley Periodicals, Inc.

A mutual coupling correction procedure for antenna arrays

11th International Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2005], 2005
A simple method to evaluate the mutual coupling matrix in an antenna array is presented here. This global mutual coupling correction procedure is independent of the type of antenna. The method is firstly validated for a dipole array and then for a microstrip patch antenna array.

Mutual coupling compensation of array antenna pattern

2015 IEEE International Conference on Communication Software and Networks (ICCSN), 2015
In order to analyze the impedance characteristics intuitively, the array antenna is equivalent to a port network. Based on this model, the relation between mutual coupling and mutual impedance is obtained, and a way to modify pattern considering mutual coupling is introduced.

Mutual Coupling Effects in Thinned Antenna Arrays

1974 4th European Microwave Conference, 1974
The reduction of mutual coupling effects is one interesting advantage of thinned antennas for phased array systems. This paper deals with the reflection coefficients and the antenna gain both as functions of the degree of thinning in statistically highly-thinned arrays. Appropriate statistics are derived, discussed, and experimentally tested.

Mutual coupling in monopole phased array antennas

1984 Antennas and Propagation Society International Symposium, 2005
An experimental and theoretical study of the mutual coupling in large periodic planar phased arrays of cylindrical monopoles is addressed. Results are given for the passively terminated array coupling coefficients from which the active array scan impedance is computed. Element gain patterns are also presented.

MUTUAL COUPLING IN ARRAY ANTENNAS

1966
Abstract : The report summarizes the current level of understanding of the performance of arrays of real radiators. The extent and nature of the effects of mutual coupling (element pattern distortion, element impedance variation with scan angle, and polarization variation with scan angle) in array antennas are investigated for a variety of array ...

Mutual coupling effects on adaptive antenna arrays

International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990
The authors examine the effects of mutual coupling on an adaptive array system and propose the use of scalar spherical modes (SSMs) to predict and correct the problem. Preliminary results are presented: the receive patterns of an ideal ten-element half-wave dipole array and a ten-element half-wave dipole array with mutual coupling are shown.

Mutual coupling in microstrip antenna array elements

2006 First European Conference on Antennas and Propagation, 2006
The mutual coupling between adaptive antenna array elements degrades the performance of the array especially for direction finding purpose. There are many possible ways to compensate the coupling effects via electromagnetic analysis or via signal processing. We are going to follow the first approach to determine the mutual coupling and we are following
