ABSTRACT:
System and method for controlling an antenna beam. The system can include a slot array (100) having a plurality of slot elements (102) and a fluid control system (206, 207, 302) responsive to a control signal301. The fluid control system can independently vary a selected volume of a fluid dielectric (300) coupled to each of the slot elements (102). In so doing, the system can steer and shape an electromagnetic field incident on the slot array. The slot array (100) can optionally comprise at least one conductive ground plane (308) for reflecting the incident electromagnetic field.
