Abstract
in this paper a dual polarized antenna array with shaped beam for outdoor WiFi access points, e.g. hotspots operating at the upper WiFi frequency band of 5.8 GHz is described. The aperture is composed of 64 waveguide antenna elements. By controlling the amplitude and the phase of only 24 elements, a shaping of the pattern in the main beam is achieved. Both polarisations are also excited by each antenna element. The presented base station array has therefore a broad half power beamwidth allowing for an easy alignment/installation of the base stations in the field. Last but not least, it shows low correlation factors which mean that it can be also used for MIMO antenna systems.
