TLDR
In this paper, the authors proposed a method to calculate the required pre-perturbed incident excitation for each array element to compensate for the effects of mutual coupling with the other elements of the array.
Abstract: 
The method operates in transmit mode an array antenna system including a plurality of antenna elements (1-N) so that the signal radiated from the antenna has a desired antenna radiation pattern, by : calculating, for each array element, the required pre-perturbed incident excitation (ai) to compensate for the effects of mutual coupling with the other elements of the array, whereas, the required pre-perturbed incident excitation (ai) for an array element generates, after mutual coupling, a resultant desired voltage (vi) on the array element which, in combination with the other compensated elements of the array, produces the desired antenna radiation pattern, and applying to each element of the array, the calculated pre-perturbed incident excitation (ai) for said element.

Mutual coupling compensation in small planar array antennas

PB Darwood, +2 more
TL;DR: In this paper, a technique for compensating for mutual coupling in linear arrays is extended to include small planar antenna arrays, which consists of the calculation of the coupling coefficients between the array elements, which are then formed into a matrix and used to compensate for the effects of mutual coupling.
