With the overview of present MIMO antenna research, the thesis brings forward a new kind of polar diversity antenna array applied in MIMO base stations, which elements are planar printed dipoles. The beamforming technology is used to obtain a particular type of elevation pattern, which has square cosecant characteristic.

本文在對目前MIMO 天線領(lǐng)域的研究動態(tài)進行概述的基礎(chǔ)上，結(jié)合基站的自身特點自拍视频日韩在线，提出并實現(xiàn)了一種新型的基站極化分集波束賦形天線陣列九九性爱，其陣元為平面印刷偶極子，陣列在俯仰面形成類似平方余割形式的方向圖分布欧美一级黄色A片。

A kind of best baffle-beard suitable for applications in the dual-frequency base station antenna is presented, meanwhile, we adopt the PSO algorithm to optimize the parameters affecting antenna pattern such as the phase of the elements, the space between the elements, such that the pattern of antenna can be shaped in the vertical plane （the pattern in the vertical plane has Cosecant beam in the service area）.

針對我國移動通信頻率，以基站天線的雙頻工作以及陣列波束賦形為目標(biāo)大黄色视频，設(shè)計了一種滿足基站天線雙頻輻射要求的最佳反射板形狀中文字幕第二一区，并通過PSO全局優(yōu)化算法優(yōu)化各單元饋電相位并調(diào)整其間距以實現(xiàn)垂直面方向圖雙頻波束賦形的目的（即垂直面方向圖在所覆蓋的服務(wù)區(qū)域內(nèi)具有余割波束）。

This set used a unique "cosecant squared" antenna that gave a true representation of the ground surface mapping, rather than a distorted slant-range picture. It's things like this that made life better for bombardiers.
