Abstract
A dielectric lens antenna (100) includes a dielectric lens unit (101) having a plurality of cavities (106) and at least one fluidic dielectric having a permittivity and a permeability. The antenna further includes at least one composition processor (104) adapted for dynamically changing a composition of the fluidic dielectric to vary at least one of among the permittivity and the permeability in any of the plurality of cavities and a controller (102) for controlling the composition processor to selectively vary at least one of the permittivity and the permeability in at least one of the plurality of cavities in response to a control signal (105).
