A reflector (38) includes a mirrored surface (48) and a frequency selective surface (46). The frequency selective surface (46) is arranged to reflect radiation of a first frequency band (52) and allow radiation of a second frequency band (50) to pass. The mirrored surface (48) is arranged to reflect radiation of the second frequency band (50). In this manner, the focal power for radiation of the first frequency band (52) is independent to the focal power for radiation of the second frequency band (50). Accordingly, the design of optical components associated with the second frequency band50can be undertaken independently of those associated with the first frequency band (52) so as to achieve the optimised focusing for each frequency band.

A radiating antenna capable of generating or receiving radiation using a plurality of feeds and a dielectric resonator of various cross-sections is disclosed. The purpose of using multiple feeds with a single dielectric resonator antenna is to produce several beams each having a "boresight" in a different direction. Several such beams may be excited simultaneously to form a new beam in any arbitrary direction. The new beam may be incrementally or continuously steerable and may be steered through a complete 360 degree circle. The invention may be combined with an internal or external monopole antenna so as to cancel out the antenna backlobe or otherwise resolve the front/back ambiguity that arises with this type of dielectric resonance antenna.
