Abstract:
An active antenna system comprises a coupling block adapted to sample a portion of a first telecommunication signal and a compensation block. The compensation block is coupled to the coupling block and is adapted to apply at least a phase compensation to the portion of the first telecommunication signal, thereby obtaining a first compensation signal. The coupling block is further adapted to combine the first telecommunication signal and the first compensation signal into a compensated first telecommunications signal to be fed into an antenna arrangement.
