图 4-6为三个天线辐射***在常温常压下 0.5GHz-3.0GHz反射系数曲线 示意图, 从图中可以看出, 根据不同运营商和智能终端的不同要求, 本发明 实施例提出的方法都能够满足不同的频段要求, 例如, LTE网络的接收频段 范围为 0.7-0.9GHZ和 1.7-2.1GHZ, 从图中可以看出本发明提出的方法能够满 足 LTE网络的频段要求。
本发明实施例的金属框天线, 在金属框上设置缝隙, 将金属框隔离为天 线部分和非天线部分, 并且直接利用金属框的天线部分实现天线辐射***。 本发明实施例的金属框天线结构不是将整个金属框作为天线的辐射单元, 而 仅将金属框的天线部分作为天线的辐射单元, 从而降低了手对天线信号的影 响。
较佳地, 金属框上的缝隙的宽度主要与天线的接收频率相关, 因此, 根 据天线要接收的频率可以灵活设置金属框上缝隙的宽度。
较佳地, 通过在金属框上设置开口缝隙, 隔离天线辐射***中的分集天 线辐射***和 GPS天线辐射***, 从而消除了二者各自接收信号之间的相互
干扰。
本发明实施例还提供一种包括上述金属框天线的终端。
需要说明的是, 以上所述的实施例仅是为了便于本领域的技术人员理解 而已, 并不用于限制本发明的保护范围, 在不脱离本发明的发明构思的前提 下, 本领域技术人员对本发明所做出的任何显而易见的替换和改进等均在本 发明的保护范围之内。
工业实用性
本发明实施例的金属框天线, 在金属框上设置缝隙, 将金属框隔离为天 线部分和非天线部分, 并且直接利用金属框的天线部分实现天线辐射***。 本发明金属框天线结构不像相关技术那样, 将整个金属框作为天线的辐射单 元, 而仅将金属框的天线部分作为天线的辐射单元, 从而降低了手对天线信 号的影响。
