Abstract
An antenna system and method comprising an antenna having 2+N antenna elements, where N is zero or an odd integer, an algorithm controlled switching circuit having a separate switch associated with each of the elements and a switch control selectively causing the switching circuit to couple an adjacent pair of the antenna elements to their associated switches while maintaining the remaining switches uncoupled from their associated antenna elements. The algorithm controlled switch control includes circuitry for successively coupling each adjacent antenna element pair of the antenna elements to their associated switches, determining a predetermined parameter for each of the antenna element pair and then causing the antenna system to operate with only one of the antenna pairs responsive to determination of the predetermined parameter. The centers of all of the antenna elements are directed in one or the other of two opposite directions and the center of each of the antenna elements is disposed at a different vertex of an equilateral polygon having N sides.
