ABSTRACT:
There is provided an antenna arrangement for use in an ultra-wideband network, the antenna arrangement comprising a plurality of active elements for emitting radio signals; and a reflecting structure disposed between at least two of the active elements for reflecting radio signals, the reflecting structure comprising an outer reflecting surface for reflecting radio signals in a first frequency range within a frequency band and an inner reflecting surface for reflecting radio signals having a second frequency range within the frequency band. In an alternative embodiment, the antenna arrangement comprises an active element for emitting radio signals, and a reflecting structure. The reflecting structure comprises a first surface for reflecting radio signals having a first frequency range within a frequency band, the first surface being substantially transparent to radio signals outside the first frequency range, and a second surface for reflecting radio signals passed by the first surface, the second surface reflecting radio signals having a second frequency range within the frequency band.
