| Abstract: | This letter describes how a circular array may be phased to produce a main beam in one direction by feeding the elements from a set of series-connected phase shifts. The direction of the main beam may consequently be varied by control of the values of phase shift. The significant feature of the series-feeding technique is the small phase deviation required per phase changer for 360° beam steering. |
