摘要

本文描述了一种用于室外WiFi接入点的异形波束双极化天线阵列，例如工作在WiFi上频段5.8 GHz的热点。该孔径由64个波导天线单元组成。通过控制仅24个单元的振幅和相位，实现了主波束中图案的整形。两个极化也被每个天线单元激发。因此，所提出的基站阵列具有宽的半功率波束宽度，允许在现场方便地对准/安装基站。最后但并非最不重要的是，它显示出低相关因素，这意味着它也可以用于MIMO天线系统。

A MIMO antenna array with shaped beam in waveguide technology for WiFi base stations

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.
