Analysis of a linear antenna array including the effects of mutual coupling

A tutorial on the analysis of linear antenna array performance is presented. Use is made of a rapidly converging algorithm for the calculation of element currents that include the effects of mutual impedance. The procedure makes it possible to introduce realistic antenna problems into an advanced undergraduate or first graduate antennas course. The procedure is straightforward, and lends itself to teaching the topic by an axiomatic approach. The numerical examples illustrate in principle which of the parameters of the array are affected by the mutual coupling, and to what extent.<
