ACTIVE ANTENNA ARRAY FOR A MOBILE COMMUNICATIONS NETWORK WITH MULTIPLE AMPLIFIERS USING SEPARATE POLARISATIONS FOR TRANSMISSION AND A COMBINATION OF POLARISATIONS FOR RECEPTION OF SEPARATE PROTOCOL SIGNALS

摘要

The present disclosure teaches an active antenna array for a mobile communications network. The active antenna array comprises a plurality of first polarisation antenna elements and a plurality of second polarisation antenna elements. The plurality of first polarisation antenna elements is connected to a first protocol signal generator. The plurality of first polarisation antenna elements are adapted to radiate an individual first protocol transmit signal. An individual one of the plurality of second polarisation antenna element is connected to an individual one of a plurality of second protocol signal generators. The plurality of second polarisation antenna elements is adapted to radiate an individual second protocol transmit signal. An individual one of the plurality of first polarisation antenna elements and the individual one of the plurality of second polarisation antenna elements are adapted to receive both, an individual first protocol receive signal and an individual second protocol receive signal.
