An antenna ( 100 ) includes an antenna radiating element ( 108 ) that is at least partially comprised of a conductive fluid ( 104 ). A dielectric structure ( 102 ) defines at least one cavity ( 110 A, 110 B) for constraining the conductive fluid. The antenna also includes a fluid control system ( 116 A, 116 B, 118 A, 118 B, 120 A, 120 B, 122 ) for selectively adding and removing the conductive fluid from the cavity for controlling a dimension of the antenna radiating element ( 108 ). The antenna radiating element ( 108 ) can be comprised of a plurality of cavities ( 110 A, 110 B), with each cavity defining a segment of the antenna radiating element ( 108 ).
