Element Pattern Prediction in Mutually-Coupled Arrays Through Isolated Antenna Characterization

Paper in proceeding, 2017

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.
