ANTENNENEINRICHTUNG FÜR EINE FUNKBASISSTATION IN EINEM ZELLULAREN FERNSPRECHSYSTEM

摘要

An apparatus comprises a first and a second input connection for a first (D1) and a second (D2) data stream, and a first and a second polarization former, one for each of said data streams. The apparatus further comprises a first and a second antenna of respective first and second polarizations, and one amplifier each. The apparatus further comprises a first and a second combiner, so that the outputs from the polarization formers may be combined as input to each of the first and second antennas.
