Abstract

The present invention relates to an antenna arrangement for use in a wireless communication system, where the arrangement comprises at least two single-polarized antenna functions. Each antenna function is adapted for radiating an antenna radiation lobe pattern having a horizontal extension in an azimuth plane, and a vertical extension in an elevation plane, perpendicular to the azimuth plane. The antenna functions both have a first polarization in a first direction. In a second direction separated from the first direction, the second antenna function has a second polarization and the first antenna function has a third polarization, the second polarization and the third polarization being orthogonal to each other.

Description

technical field [0001] The present invention relates to antenna devices for use in wireless communication systems. The device comprises at least two single polarized antenna functions adapted to radiate an antenna radiation lobe pattern having a horizontal extent in the azimuth plane and a vertical extent in an elevation plane perpendicular to the azimuth plane. The antenna functions all have substantially a first polarization in a first direction. [0002] The invention also relates to a node in a wireless communication system comprising an antenna device according to the above. Background technique [0003] In cellular systems for wireless communication, different kinds of base stations are commonly used. Typical base stations (BSs) in cellular systems are often deployed at roof level or in tall antenna towers to increase their coverage area. This gives a high probability of line-of-sight between base stations, which can lead to severe BS-to-BS station interference, esp...
