Abstract
An active antenna system and a method for relaying radio signal in the mobile communications network is disclosed. The active antenna system comprises a plurality of antenna elements for relaying radio signals at a first frequency band. The antenna elements are connected to a plurality of signal paths. A plurality of signal inputs for inputting radio signals at a second frequency band is connected to the signal paths. A plurality of first mixers in the signal paths converts the frequency of the radio signals between the first frequency band and the second frequency band. A single first local oscillator is connected to the first mixers through a first oscillator signal path and supplies first oscillator signals to the first mixers and at least one dispersion element is connected to at least one of the signal paths.
