Abstract:
A reconfigurable antenna comprises a plurality of antenna feed elements, a plurality of plasma switches respectively associated with the antenna feed elements, and control circuitry for independently operating the plasma switches to selectively activate and deactivate the antenna feed elements. Each plasma switch may comprise a volume of inert gas, and a pair of electrodes spanning the respective volume of inert gas. The reconfigurable antenna may comprise a power supply for supplying a voltage to the pair of electrodes of each of plasma switch sufficient to ignite the respective inert gas volume into a plasma field to deactivate the respective antenna feed element.
