為了能夠滿足基站易于選址、優質快速的建站要求和易維護、低成本、高可靠的運行要求，本文對以方艙來實現一體化結構基站做出一番探討。從系統設計的觀點闡述了移動通信高性能基站天線設計的幾個關鍵問題，介紹了智能天線技術在基站中的應用，并且用HFSS軟件仿真了一種新型的對稱陣子天線，該天線駐波比小于2的帶寬可以達到60%，具有良好的寬頻帶特性。
Abstract:
In order to meet the station construction requirement of easy site selection and fast base station， and meet the operational requirement of easy maintenance， low cost and high reliability， this paper discussed the unified architecture base station using shelter. Several key problems of high performance mobile communication base station antenna were illustrated from the view of system design， the application of smart antenna in base station was also introduced. And a novel dipole antenna was simulated by using HFSS， the VSWR of the antenna is less than 2， and the bandwidth was reach to 60%. So it has good broadband properties.
Abstract: Most hand-held products lack accurate battery-charge monitors ("fuel gauges") because of the misconception that an accurate fuel gauge is difficult to achieve. This article debunks the myths and discusses how to accurately monitor charge at all temperatures, charge and discharge rates, and aging conditions.
