An antenna can include at least one antenna element () to which a fluid dielectric () is magnetically and electrically coupled. The antenna element () is preferably a conductive wire or patch disposed on a dielectric substrate (), but it can also be a slot. A fluid control system () can be provided responsive to a control signal () for selectively varying a volume of the fluid dielectric () coupled to the antenna element (). Consequently, efficient operation of the antenna element can be provided on a plurality of operating bands.
