ABSTRACT:
A reflector antenna (100) comprises a reflector unit (101) having a plurality of cavities (106), 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 any of the plurality of cavities. 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 plurality of cavities in response to a control signal (105).
