ELECTRONICALLY RECONFIGURABLE ANTENNA

摘要

An electronically reconfigurable antenna includes individual antenna elements which can be reconfigured as active or parasitic elements in the process of variable mode operation. In the antenna, an active subset of antenna elements excites a Wave on a parasitic subset of antenna elements, which are controlled by a plurality of electronically variable reactances. The plurality of electronically variable reactances. is used to provide the reconfigurable array, which may operate in a plurality of modes of wave propagation. Furthermore, the plurality of variable reactances allow compensation for the inherently narrow operating bandwidth of the high-gain surface wave antennas.
