ABSTRACT:
A reflector antenna (100) includes a reflector unit (191) having at least one cavity (192) disposed in the reflector unit, at least one fluidic dielectric (180) having a permittivity and a permeability, and at least one composition processor (101) adapted for dynamically changing a composition of the fluidic dielectric to vary at least the permittivity or permeability in at least one cavity for the purpose of dynamically altering the illumination taper of the reflector antenna. The antenna further comprises a controller (136) for controlling the composition processor in response to a control signal (137).
