Abstract
A method and apparatus for electronically steering an antenna system is provided. A surface wave is propagated along each of a number of surface wave channels formed in each of a plurality of radiating elements to form a radiation pattern. Each surface wave channel in the number of surface wave channels formed in each radiating element in the plurality of radiating elements is coupled to a transmission line configured to carry a radio frequency signal using a surface wave feed in a plurality of surface wave feed associated with the plurality of radiating elements. A main lobe of the radiation pattern is electronically steered by controlling voltages applied to a plurality of switch elements connecting a plurality of impedance elements in each of the number of surface wave channels.
