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.

Compensating for the mutual coupling effect in a normal-mode helical antenna array for adaptive nulling

IEEE Transactions on Vehicular Technology, 2003
A practical normal-mode helical antenna array together with a new method for the compensation of mutual coupling effect is proposed for the efficient adaptive nulling of interferences in a mobile communication environment.

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.

Interval-Bounded Optimal Power Pattern Synthesis of Array Antenna Excitations Robust to Mutual Coupling

IEEE Antennas and Wireless Propagation Letters, 2023
A method for the optimal synthesis of linear phased arrays when calibration errors and mutual coupling are present is proposed. Starting from the knowledge of the mutual coupling model and of the calibration tolerances, the circular interval analysis ...

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 ...

Singular Metric for Antenna Array Mutual Coupling: Unveiling the Array Coupling Index (ACI)

United States National Committee of URSI National Radio Science Meeting
In this paper, we present a novel approach for quantifying mutual coupling within antenna arrays. Our method introduces a unified metric, referred to as the Array Coupling Index (ACI), which succinctly captures the collective mutual coupling effect among

Mutual coupling cancelation for compact transmit antenna arrays

2011 IEEE Wireless Communications and Networking Conference, 2011
Mutual coupling between elements in compact transmit antenna arrays is taken into account in performance prediction and system design of multiple-input multi-output (MIMO) systems. The transmitter-end coupling matrix comprised of array impedance matrix and effective load impedance matrix is derived.

Effects of mutual coupling on the performance of STAP antenna arrays

IEEE Transactions on Aerospace and Electronic Systems, 2000
The effect of mutual coupling on the performance of space-time adaptive processing (STAP) antenna arrays is investigated. A signal model that includes the effects of mutual coupling is derived and used to compute the optimum solution for the fully adaptive and a variety of partially adaptive algorithms.

Nulling of Antenna Arrays Including the Mutual Coupling Effect

VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008
A simple and effective method is presented in this paper to account for the mutual coupling effect on the nulling of antenna arrays. Deep and precise nulls can be achieved using the method with mutual coupling effect considered. Formulas for two-element and three-element arrays are derived from a general model.

A review on Mutual Coupling Reduction Methods for Antenna Arrays

Proceedings of the 4th International Conference on Big Data and Internet of Things, 2019
In telecommunications domain, device components miniaturization is a major need. In case of the antenna array structures, reducing the overall size of the antenna leads engineers to place them closer to each other. In this case some undesirable electromagnetic phenomena can occur such as antennas interferences in the near field and surface wave ...
