背景技术
目前很多的USB(Universal Serial Bus，通用串行总线)数据卡，不仅具有LTE(Long Term Evolution，长期演进)天线功能，用于为PC(Personal Computer，个人电脑)等提供上网功能，还通过在LTE主板上加入WIFI(WIreless-Fidelity)模组，使USB数据卡同时具有提供WIFI热点的功能。但是目前这种在LTE主板中内置WIFI天线，会使得LTE天线主板布局过于紧凑而带来设计及调试上的多种问题，如主板杂讯干扰、WIFI-2.4G与LTE TDD(Time Division Duplexing，时分双工)B40间的互扰等，同时还因增加了WIFI模组而造成SAR(Specific Absorption Rate，比吸收率)值叠加，使得USB数据卡辐射值超标等问题。
