An antenna system of the type wherein the radiating pattern may be controlled to direct the radiation of a signal in a selected direction. The system includes a plurality of radiating elements which are affixed to a coplanar in planes which are equiangular from each other. In response to a selected direction of radiation, control circuitry applies the signal to the coplanar antenna elements which are in a plane perpendicular to the selected radiating direction. Further, the control circuitry varies the electrical length of the remaining elements such that some act to direct, and other reflect the radiated signal. |
