FA/D内置合路器可独立电调天线深度研究

摘要

There are four standards in the China Mobile network,including GSM900,DCS1800,TD-SCDMA and TD-LTE. With the de-velopment of the LTE network,the surface resources become increasingly tense. The demand for antenna which supports both FA and D frequency band is urgent. The FA/D independent electrical down-tilt control antenna with built-in combiner can be electrical y adjustable in FA and D frequency band simultaneously. It realizes the independent optimization adjustment of two frequency bands and maximizes the performance optimization of the network. It analyzes the influence on the coverage and throughput of the network based on different combination of down-tilt angle in different frequency band. It also verifies that this antenna plays a very important role in dense urban areas in TD-SCDMA and TD-LTE network.%中国移动现网包含GSM900、DCS1800、TD-SCDMA和TD-LTE 4种制式，随着中国移动LTE网络建设的不断开展，天面资源日趋紧张，FA频段和D频段共天线的需求愈发强烈。FA/D内置合路器可独立电调天线既可实现FA和D频段的共天线，又可实现2个频段天线电下倾角独立优化调整，实现一次部署的利益最大化，同时保证了双网性能最优。分析了FA/D频段不同下倾角组合对网络覆盖和下行数据吞吐量的影响，验证了该天线在密集市区TD-LTE及TD-SCDMA网络优化中起到的重要作用。
