ABSTRACT:
A reflector antenna (100) includes a reflector unit (101) having at least one cavity (106) disposed on the reflector unit, at least one fluidic dielectric having a permittivity and a permeability, and at least one composition processor (104) adapted for dynamically changing a composition of the fluidic dielectric to vary at least the permittivity or permeability in at least one cavity. The antenna further comprises a controller (102) for controlling the composition processor to selectively vary at least one among the permittivity and the permeability in at least one of the cavities in response to a control signal.
