Abstract
A new approach for the design of electronic beam steering arrays with reactive parasitic elements is introduced. The method is demonstrated at the example of a circular array formed by capacitively tuned monopoles. The related capacitances are determined straightforwardly and without any need for optimization techniques. The resulting beams are rotatable and maintain their gain and beamwidth within tight margins. Comparisons with NEC2 verify the pattern calculation.
