Abstract:
1. An active antenna system, comprising: an antenna element arrangement with a plurality of antenna elements; a first coupling block adapted to sample a portion of a first telecommunication signal in a first frequency band, the first telecommunication signal being transceived by a base transceiver station a first compensation block coupled to the first coupling block, wherein the first coupling block comprises a first filter coupled to the first compensation block, wherein the first filter is adapted for filtering transmit signals of the first telecommunication signal, the first compensation block being adapted to apply at least a first phase compensation to the portion of the first telecommunication signal and thereby obtaining a first compensation signal, the first coupling block being further adapted to combine the first telecommunication signal and the first compensation signal into a compensated first telecommunications signal for feeding into one of the plurality of antenna elements; a bandpass filter coupled to a passive feeding network and adapted to filter the first telecommunication signals in said first frequency band; an active transceiver arrangement adapted to transceive a second telecommunication signal in a second frequency band; a combining element for combining the compensated first telecommunications signal and said second telecommunication signal into a combined telecommunications signal for feeding into one antenna element of the antenna element arrangement.
