Abstract: 

In current commercial markets, most of base station antennas are the single beam linear antenna arrays. In this presentation, we first discuss some capacity and coverage issues related to those "normal" single beam antennas. Then several possible solutions such as bi-sector array and tri-sector array are introduced and detailed array architectures of planar antenna arrays are described. Based on multi-beam antenna requirements, some unique relationships between the antenna structures and key parameters such as gain, azimuth side-lobe level, and cross-over point are identified and the basic design procedures for different applications such as fixed electrical tilted (FET) and  variable electrical tilted (VET) are presented. As one of key components, some basic antenna elements for the planar base station antennas are analyzed carefully. Finally, some advanced technologies for future high performance and low cost planar antenna arrays are discussed.
