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 signal 301 . 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.
