ABSTRACT:
An antenna (100) includes at least one antenna radiating element (108, 110) and a dielectric structure (102) defining a cavity containing a fluid dielectric (106). The dielectric structure (102) can be a dielectric circuit board substrate with a ground plane (116) provided opposed to the antenna radiating elements (108, 110). The fluid dielectric (106) is electrically and magnetically coupled to the antenna radiating element. Further, a composition processor (301) is provided for selectively varying a composition of the fluid dielectric (106) so as to dynamically change an electrical characteristic of the antenna radiating element (108) in response to a control signal.
