摘要： A small sized multi sector antenna having a plurality of sectors or element antennas each having related directivity in horizontal plane so that one of the element antennas is selected for providing desired beam direction has been found. Each of the element antennas is planar or in flat disc shaped, and is, for instance, a micro-strip antenna. Each of the element antennas is located in vertical plane, and each element antenna is positioned at different height from one another so that each element antenna does not overlap with other element antennas in vertical direction. A central vertical axis of the sector antenna is defined and the element antennas are positioned with axial symmetrical relations relating to said axis.
