Element pattern prediction in mutually-coupled arrays through isolated antenna characterization

A simple method is proposed that is capable of predicting antenna array embedded element patterns based on the radiation and scattering characteristics of a single isolated antenna element. The effect of mutual coupling, which causes embedded element patterns to differ, is accounted for through the multi-scattering of electromagnetic fields between array elements. This is a post-processing step and therefore obviates the need to run time-consuming full-wave electromagnetic field simulations, which is particularly important when numerous antenna array configurations need to be analyzed rapidly. The accuracy of three single-scattering versions of the pattern prediction method are evaluated on a range of two-element dipole arrays.
