ANTENNA WITH AN IMPROVED RADIATION PATTERN

摘要

An antenna device for a telecommunications system, comprising a first antenna with a first radiation pattern and a second antenna with a second radiation pattern. The radiation patterns give the two antennas different coverage in the vertical plane of the antenna device, and the first and the second antennas are used for diversity purposes. The difference in vertical coverage between the first and the second antenna is such that at least the first null points in the vertical plane of the two radiation patterns do not coincide with each other.
