The invention discloses an antenna device (500, 600, 700) for a radio base station in a cellular telephony system, which comprises a first and a second input connection for a first (Dl) and a second (D2) data stream, and a first (510, 610, 710) and a second (511, 611, 711) polarization former, one for each of said data streams. The device also comprises a first (530, 630, 730) and a second (532, 632, 732) antenna of respective first and second polarizations, and one amplifier each. The device also comprises a first (515, 615, 715) and a second (516, 616, 716) combiner, so that the outputs from the polarization formers may be combined as input to each of the first and second antennas.

L'invention concerne un dispositif d'antennes (500, 600, 700) pour une station de base radio dans un système de téléphonie cellulaire, qui comprend une première et une seconde connexions d'entrée pour un premier (D1) et un second (D2) flux de données, et un premier (510, 610, 710) et un second (511, 611, 711) formeurs de polarisation, un pour chacun desdits flux de données. Le dispositif comprend également une première (530, 630, 730) et une seconde (532, 632, 732) antennes de première et seconde polarisations respectivement, et un amplificateur chacune. Le dispositif comprend également un premier (515, 615, 715) et un second (516, 616, 716) combineurs, de sorte que les sorties des formeurs de polarisation peuvent être combinées en tant qu'entrées sur chacune des première et seconde antennes.
