一种新型高增益4G天线
本技术涉及一种天线,尤其是一种新型高增益4G天线。
技术介绍
天线作为无线通讯设备不可缺少的关键部件,用来发射或接收无线电波以传递无线信号,天线是整个无线通信设备的前端,其性能的优劣对整个设备的性能起着至关重要的作用。随着移动通信技术的飞速发展,带宽拓展一直是终端天线发展的方向,在2G、3G的基础上,4G网络正逐步实现全面覆盖。考虑到世界各地采用的通信协议和划分频段不尽相同,为实现全球漫游,移动终端天线需要支持多频段覆盖;4G覆盖的频段有GSM850(824-894MHz)、GSM900(880-960MHz)、DCS(1710-1880MHz)、PCS(1850-1990MHz)、UMTS(1920-2170MHz)、LTE2300(2300-2400MHz)、LTE2500(2500-2690MHz)。因此,支持4G的移动终端天线一般要求覆盖824~960MHz、1710~2690MHz频段。为了实现覆盖上述4G频段,典型的设计方法是采用三维结构,如螺旋天线、PIFA天线和折叠单极子天线,这类天线有较多的设计自由度,一般能够满足频段覆盖要求,但是不利于加工和高度集成,一般安装在车体或船体的金属外表面,难以共形易损坏。贴玻璃天线安装在玻璃的内表面,全部结构都在车或船的内部,安全可靠性高;为了避免遮挡视线,要求贴玻璃天线体积小,与玻璃共形,与天线的多频段覆盖要求相矛盾,存在着设计难题。因此,现有技术有待于提高和改善。
