Polynomial approach to study of single-ring circular antenna array

The antenna arrays considered consist of identical parallel dipoles equally spaced around, and perpendicular to, a circle. The method of polynomial decomposition used to determine the phase sequence currents has proved to give excellent results. Moreover, the accuracy of the results can be very easily increased by simply increasing the order n of the polynomial. The other main advantage of the method over the other existing methods is its very simple programming logic. A comparison of theoretical and experimental results is presented.
