Description

天线复用方法及移动终端
本申请要求享有于2015年11月20日提交中国专利局、申请号为201510812996.0、名称为“无线局域网MIMO分集天线复用蜂窝天线的方法及终端”的中国专利申请的全部优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及天线复用领域，特别是涉及一种天线复用方法及移动终端。
背景技术
目前，主流的移动终端，如，手机、PAD等普遍都具备无线局域网(Wireless Local Area Networks，WLAN)和蜂窝网Cellular数据服务。为提高移动终端的数据吞吐量，硬件平台通常均提供双天线实现方案。对于Cellular天线技术，分集天线技术已经涵盖到2G/3G/4G各种制式。一方面，提供分集接收增益，一方面，现在全金属外壳的移动终端是个流行趋势，如高通提供的ASDiv(Antenna Switch Diversity，天线开关分集技术)算法用于应对手握等操作导致的一根天线性能急剧恶化的场景，解决金属机壳的“死亡之握”天线难题。对于WLAN，天线技术，第二根天线的引入带来的好处同样受益匪浅。
手机等移动终端产品是个高度集成的电子产品，天线数量和频率覆盖的需求大大增加了天线开发的难度。天线相互备份和复用的技术不断被引进。
最新的高通公司的天线设计方案为蜂窝网Cellular分集天线用于无线局域网WLAN(只适用于2.4GHz或只适用于5GHz或2.4GHz&5GHz都适用，共三种方式)多入多出(Multiple-Input Multiple-Output，MIMO)技术中的分集天线。这个方案的最大收益在于将Cellular分集天线的作用最大化，即复用作WLAN MIMO的分集，从而不需要在增加单独的天线。
但，这种方案的缺点在于：
高通推荐的这个方案是分频段天线方案，实际上很多移动终端的公司通常采用全频段天线方案。高通方案中对Cellular分集天线的2.4GHz(和/ 或)5GHz性能有要求，这将会加大全频段分集天线设计的难度。如果天线开发时在保证Cellular频段需要的前提下无法兼顾无线局域网WLAN频段的天线性能，即蜂窝网分集天线用作无线局域网WLAN天线时导致性能极差。
因此，如何提供一种天线复用方法及移动终端，使得实现全频段天线设计方案成为亟待解决技术问题。
