Abstract
An antenna of the type having a central driven element and a plurality of surrounding parasitic elements is shown. Further, there is circuitry for modifying the basic omnidirectional pattern of said antenna to a directional pattern by normally capacitively coupling the parasitic elements to ground but on a selective basis changing some of the parasitic elements to be inductively coupled to ground whereby they act as reflectors and provide an eccentric signal radiation pattern. By cyclically altering the connection of various parasitic elements in their coupling to ground, a rotating directional signal is produced.
