ABSTRACT:
An antenna can comprise a conductive reflecting surface (204) and a plurality of cells (202) disposed over the conductive reflecting surface. The plurality of cells can be formed from a solid dielectric material such as a low temperature cofired ceramic. Each cell can define a cavity for containing at least a fluid dielectric (406). One or more fluid processors (404, 424) independently vary a volume of the first fluid dielectric in the plurality of cells for producing a redirected RF beam at a selected angle relative to an incident RF signal impinging on the conductive reflecting surface.
