Abstract
Mutual coupling in antenna arrays has been a deterrent issue for design accuracy and predictions. Several techniques for calculation, reduction, and compensation of mutual coupling were proposed in the past; the techniques include both analytical and numerical approaches. However, the methods of mutual coupling mitigation in context of radiation pattern correction had been very few. Here, mutual impedances are calculated through a conventional technique and is used to form a set of network equations whose parameters are assimilated with those of a desired radiation pattern; the proposed technique directly leads to the calculation of feed currents, required in the antennas, for restoring the mutual coupling affected radiation pattern to the desired pattern. The technique is accurate with lesser computational complexity compared with the extant methods.Keywords
