Abstract
The embodiments herein relate to radio sheet system at high frequencies. In an embodiment, there proposes a lens antenna system, comprising: a lens; a plurality of antenna sets attached to the lens; and a multiplexer connected to the plurality of antenna sets, for selectively activating an antenna set of the plurality of antenna sets, in order that a collimated beam is emitted through the lens from the activated antenna set. With embodiments herein, only one antenna is used to transmit a beamformed beam by lens with collimation capability, thus the embodiments may provide an alternative and more efficient way to replace beamforming functionality.
