技术领域
本发明涉及一种基于适用于多频段的天线结构及包括该天线结构的无线通信装置。
背景技术
随着现代通信技术的发展，移动装置成为人们生活中不可或缺的一部分，通信系统对通信效率要求越来越高。第五代移动通信技术5G可实现速度更快及网络容量更大的通信需求，而为了实现这个需求使用多天线设计MIMO(Multiple-Input Multiple-Output，多入多出)架构是常用的设计。但是在移动装置的有限空间内同时放入适用于2G、3G、4G天线和5G MIMO等多个天线的架构对天线设计与移动装置结构设计是重大的课题。
发明内容
有鉴于此，有必要提供一种适用于多频段的天线结构及包括所述天线结构的无线通信装置。
一种天线结构，应用于无线通信装置中，所述天线结构包括第一天线、第二天线及铁氧体磁珠模块，所述第一天线与所述第二天线通过所述铁氧体磁珠模块连接，当所述天线结构工作于第一频段时，所述第一天线与第二天线断开，所述第二天线独立收发无线信号；当所述天线结构工作于第二频段时，所述第一天线与第二天线连接，并共同收发无线信号，所述第一频段高于第二频段。
一种无线通信装置，包括所述天线结构。
所述天线结构通过所述多个铁氧体磁珠串联连接所述第二天线的所述多个5G天线及所述第一天线，并通过所述多个铁氧体磁珠在不同频段下的阻抗特性，使所述多个5G天线在5G频段相互独立，同时收发无线信号，从而提高了通信效率；并使所述多个5G天线与所述第一天线在2G、3G、4G频段相互连接，以共同收发无线信号，节省了2G、3G、4G天线的设计空间。从而，所述天线结构兼容收发2G、3G、4G、5G的无线信号，具有应用广泛的功能。

如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
请参阅图1，本发明第一实施例提供一天线结构100，应用于无线通信装置200。所述无线通信装置200可为但不限于为移动电话、平板电脑、笔记本电脑及个人数字助理(personal digital assistant，PDA)等。所述无线通信装置200通过所述天线结构100收发多频段的无线信号，以实现无线通信。
所述天线结构100包括第一天线12、第二天线14、铁氧体磁珠模块16及处理器18。本实施例中，所述天线结构100可设置于一电路板(图未示)上，所述电路板为所述天线结构100提供必要馈入电源及接地。可以理解，所述天线结构100也可设置于其他载体上，例如所述无线通信装置200的壳体，以及通过其他方式进行馈电及接地，例如通过金属壳体进行接地处理。
所述第一天线12为2G/3G/4G天线，用于收发2G、3G、4G频段的无线信号。本实施例中，所述2G/3G/4G天线可根据无线通信装置200的设计要求，呈现多种不同的结构。
所述第二天线14为5G天线阵列，包括多个依次串联连接的5G天线，所述多个5G天线用于收发5G频段的无线信号。本实施例中，所述多个5G天线的结构及排列可根据无线通信装置200的设计要求而呈现多种方式。本实施例中，所述5G天线阵列包括8个5G天线141-148。
所述铁氧体磁珠模块16可为片状铁氧体磁珠(Chip Ferrite Beads)，包括多个铁氧体磁珠(Ferrite Beads)，用于分别一一连接所述多个5G天线以及连接所述第一天线12及第二天线14。本实施例中，所述铁氧体磁珠模块16包括8个铁氧体磁珠161-168，每两个所述5G天线141-148之间连接有一个所述铁氧体磁珠162-168，所述5G天线141与所述第一天线12之间连接有一个所述铁氧体磁珠161。从而，所述第一天线12与多个5G天线141-148通过所述多个铁氧体磁珠161-168形成串联连接。请参图2，本实施例中，多个所述铁氧体磁珠161-168为在3000MHz以上频段具有高阻抗特性及在2690MHz以下频段具有低阻抗特性的被动元件。
所述处理器18通过多条信号线分别电性连接至所述第一天线12及所述第二天线14的多个5G天线141-148，用于为提供所述第一天线12及所述第二天线14馈入电流及必要的匹配等，以使所述第一天线12及所述第二天线14工作于多个频段。
可以理解，所述第一天线12及所述第二天线14的多个5G天线141-148均具有接地端，例如通过电路板或所述无线通信装置200的壳体接地。
当所述处理器18分别向所述第一天线12及所述第二天线14的多个5G天线141-148馈入电流，电流沿所述第一天线12及所述第二天线14的多个5G天线141-148流动，以激发一第一模态及一第二模态以产生第一频段及第二频段的辐射信号。本实施例中，所述第一模态包括5G模态，所述第一频段包括5G频段5000-6000MHz；所述第二模态包括低频模态、中频模态及高频模态，所述第二频段包括低频频段699-960MHz、中频频段1710-2170MHz及高频频段2300-2690MHz，也即所述第二频段的辐射信号包括了2G、3G、4G频段。
当所述天线结构100工作于所述第一频段时，即工作于3000MHz以上的频段，多个所述铁氧体磁珠161-168具有高阻抗特性，所述多个5G天线141-148之间及与所述第一天线12之间形成断路，每一所述5G天线141-148相互独立并形成独立5G MIMO天线，同时收发无线信号，从而使得收发无线信号的速度至少达到8倍以上。当所述天线结构100工作于所述第二频段时，即工作于3000MHz以下的频段，多个所述铁氧体磁珠161-168具有低阻抗特性，所述多个5G天线141-148之间及与所述第一天线12之间形成短路，所述多个5G天线141-148与所述第一天线12依次连接(参图3)，以共同收发无线信号，从而有效增加了第一天线12的路径长度，大幅缩减2G、3G、4G天线的设计空间。
本发明的天线结构100通过所述多个铁氧体磁珠161-168串联连接所述第二天线14的所述多个5G天线141-148及所述第一天线12，并通过所述多个铁氧体磁珠161-168在不同频段下的阻抗特性，使所述多个5G天线141-148在5G频段相互独立，同时收发无线信号，从而提高了通信效率；并使所述多个5G天线141-148与所述第一天线12在2G、3G、4G频段相互连接，以共同收发无线信号，节省了2G、3G、4G天线的设计空间。从而，所述天线结构100兼容收发2G、3G、4G、5G的无线信号，具有应用广泛的功能。
综上所述，尽管为说明目的已经公开了本发明的优选实施例，然而，本发明不只局限于如上所述的实施例，在不超出本发明基本技术思想的范畴内，相关行业的技术人员可对其进行多种变形及应用。
