【具体实施方式】
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合附图对本发明的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
目前,现有的移动终端(如手机、笔记本、平板电脑等)都设置有天线系统,以通过该天线系统接收和发射电磁波,实现移动终端的通信功能。常见的天线系统主要满足2G(2-Generation wireless telephone technology,第二代手机通信技术)、3G(3rd-Generation,第三代手机通信技术)和4G(the 4 th Generation mobile communication technology,第四代移动通信技术)的通信,随着人们对通信质量的要求越来越高,毫米波也用于移动终端的通信。
毫米波是电磁波的一种,具有更宽的通信带宽,但是,其波长频率较高,传输时损耗较大,因此,在实际应用中,毫米波天线必须以阵列形式存在移动终端,常见的终端毫米波阵列大多数为1维或2维阵列天线,且,在移动终端中大多是占有独立的空间,从而导致移动终端中其他结构的空间减少,造成了移动终端的空间资源浪费。
基于此,本发明实施例提供了一种移动终端及天线系统的切换方法,可以 有效缓解上述问题。
为便于对本实施例进行理解,首先对本发明实施例提供的一种移动终端进行详细介绍。
在本发明的一个实施方式中,提出了一种移动终端,图1示出了本发明实施例提供的一种移动终端的结构示意图,如图1所示,该移动终端1设置有天线系统10,且该移动终端的天线系统包括:基础天线101、毫米波天线102和开关单元103;
其中,上述基础天线和上述毫米波天线的天线馈点设置在移动终端的金属边框20上;且,上述毫米波天线的天线馈点的数量至少有两个,以及至少两个毫米波天线的天线馈点按照预设的排列方式设置,组成阵列天线馈点;基础天线和毫米波天线均与开关单元连接,开关单元用于控制基础天线和毫米波天线的天线馈点的连接状态,以对天线系统进行调谐。
具体实现时,上述基础天线通常为满足2G、3G和4G通信的天线;而毫米波天线则是5G(5th generation mobile networks,第五代移动通信技术)通信中的关键技术。因此,通过上述开关单元控制基础天线和毫米波天线的天线馈点的连接状态,对该移动终端的天线系统进行调谐的过程,可以实现天线通常和毫米波天线同时工作的方式,有效提升移动终端的通信功能。
本发明实施例提供的移动终端,其天线系统包括基础天线、毫米波天线和开关单元;基础天线和毫米波天线的天线馈点设置在移动终端的金属边框上,毫米波天线的天线馈点的数量至少有两个,且,毫米波天线的天线馈点按照预设的排列方式设置,组成阵列天线馈点;基础天线和毫米波天线均与开关单元连接,以通过开关单元控制基础天线和毫米波天线的天线馈点的连接状态,以对天线系统进行调谐,通过天线系统的调谐过程,能够实现基础天线以及毫米波天线同时通信的方式,且,将基础天线和毫米波天线的天线馈点设置在移动终端的金属边框的方式可以充分利用移动终端的金属边框,以减少毫米波天线在移动终端内部占有的空间,从而提高了移动终端的空间利用率,便于移动终端向小型化发展。
在实际应用中,本发明实施例中金属边框的一种可能外观主视图如图2所示,其中,金属边框上设置有断点21,该断点可以增强移动终端中天线系统的通信信号,以保证整个移动终端不被金属完全封闭,从而确保通信信号不会被屏蔽,此外,金属边框上设置断点,还可以便于金属边框的安装,以及减少维修和生产的成本,需要注意的是,这里断点可以为2个或者4个,本发明对此不做限制。
进一步的,上述金属边框上还设置有屏上挖孔前摄,以便于移动终端通过该屏上挖孔前摄实现拍摄功能,此外,金属边框上还设置有音量键和电源键等 功能键对应的通孔,其中,音量键用于实现移动终端中音量的调节,电源键则用于控制移动终端的工作状态,即用于开启或者关闭移动终端,进一步,金属边框还可以包括其他组件对应的通孔,具体可以根据实际使用情况进行设置,本发明实施例对此不做限制。
进一步的,在实际应用中,上述金属边框上设置有与毫米波天线的天线馈点对应的缝隙,以构成毫米波天线对应的缝隙天线。
具体地,图3示出了一种金属边框的一种可能的外观俯视图。如图3所示,在金属边框上设置有与毫米波天线的天线馈点对应的缝隙,以构成毫米波天线对应的缝隙天线104,其中,该缝隙是通过在金属边框上将金属掏掉来实现的,且,被掏掉的金属使用塑料进行填充,这里采用塑料进行填充也可以增强毫米波天线对应的缝隙天线的通信信号强度。
在实际应用中,这里毫米波天线对应的缝隙天线包括但不仅限于矩形,也可以具有一定的倾斜角度,可根据实际需求进行设置。此外,缝隙天线的数量也可以根据实际需求进行设置,为了便于理解,这里以1×9的缝隙天线阵列为例说明,这里1×9的缝隙天线阵列的每个单元尺寸可以根据具体波段进行设计,例如,如果毫米波天线选择30GHz的频率附近的频段,且,1×9的缝隙天线阵列设置为矩形,那么1×9的缝隙天线阵列的每个单元的长边方向的尺寸可以设置为3mm左右,短边方向的尺寸可以根据金属边框的结构进行调整,且,每个阵列单元之间的距离可以设置为5mm左右,从而可以构成毫米波天线对应的1×9缝隙天线。本发明实施例提供的移动终端,通过将毫米波天线设置在金属边框上,可以减少毫米波天线在移动终端中的占有空间,以及不会影响移动终端中其他结构的位置空间,从而在结构上提高了移动终端的资源利用率。
此外,在该金属边框上还设置有基础天线的天线馈点,图4示出了本发明实施例提供的一种金属边框可能的外观内视图,如图4所示,在金属边框上,除了毫米波天线对应的缝隙天线以及毫米波天线的天线馈点22外,还包括基础天线的天线馈点23,即满足2G、3G和4G通信的天线的天线馈点,因此,该移动终端的天线系统通过开关单元控制毫米波天线的天线馈点和满足2G、3G和4G通信的天线的天线馈点的连接状态来实现2G、3G和4G通信以及毫米波天线同时通信的方式,从而满足了用户的多种需求,提高了用户的体验度。
进一步的,毫米波天线的天线馈点对应的金属边框的位置设置有凹槽,毫米波天线的天线馈点设置在凹槽位置,且,凹槽按照预设的排列方式设置。
具体地,为了满足移动终端的通信需求,凹槽的数量与毫米波天线的天线馈点的数量通常是保持一致,且,凹槽按照预设的排列方式进行设置,即凹槽的在金属边框上的具体设置方式与毫米波天线的天线馈点的排列方式保持一致,从而便于毫米波天线接收和发送电磁波,实现天线系统的通信功能。此外,在金属边框上2G、3G和4G天线的天线馈点对应的位置处也设置有凹槽,用于 设置2G、3G和4G天线的天线馈点,进而实现2G、3G和4G天线的通信功能,以及移动终端在结构上可以实现2G、3G和4G天线以及毫米波天线同时通信的功能,从而满足用户的多种通信需求,提高用户的体验度。
在实际应用中,上述开关单元为开关阵列;该开关阵列包括分别与基础天线和毫米波天线的天线馈点连接的多个切换开关,其中,每个切换开关均连接至金属边框。
图5示出了本发明实施例提供的另一种移动终端的结构示意图,参照图5,其中示出了开关阵列中与基础天线的天线馈点连接的切换开关1031,以及与毫米波天线的天线馈点连接的开关阵列1032,其中,开关阵列中包括与毫米波天线对应的缝隙天线阵列连接的多个切换开关,这里开关阵列的切换开关的数量应当与缝隙天线阵列的单元数量保持一致,且,每个缝隙天线阵列的单元均连接有切换开关,从而通过开关单元,控制基础天线和毫米波天线的天线馈点的连接状态,实现对天线系统进行调谐。
在实际应用中,上述开关阵列包括的多个切换开关均为调谐开关,该调谐开关可以包括电容、电阻和电感等器件,通过控制调谐开关中不同支路的通断状态,从而得到电容和电感的不同工作组合方式,以实现对天线系统进行调谐。为了便于理解,这里举例说明,在图5中,切换开关1031与金属边框连接,且与基础天线的天线馈点连接,因此,切换开关1031可用来对2G、3G和4G天线进行阻抗调谐,即当切换开关1031中电容和电感构成不同工作组合方式时,切换开关1031可以处于不同的状态,从而2G、3G和4G天线对应不同的频段状态。
但是在实际应用中,移动终端的天线系统仅仅依靠切换开关1031调节阻抗并不能覆盖所有的频段状态,因此,本发明实施例中,还可以利用开关阵列1032对金属边框进行孔径调谐。具体地,这里以开关阵列1032包含8个切换开关为例进行说明,其中,开关阵列1032可以是8个两路单刀双掷开关或者四路单刀单掷开关,具体选择哪种类型的切换开关,可以根据实际应用中具体的需求进行选择,本发明对此不做限制。
当上述开关阵列1032使用单刀双掷开关时,上述开关阵列1032可以至少有8种状态,因此,开关阵列1032可以至少8种状态对金属边框进行孔径调谐;如果上述开关阵列1032使用单刀单掷开关,则开关阵列1032可以具有更多状态对金属边框进行孔径调谐。
此外,由于毫米波天线与2G、3G和4G天线共同设置在金属边框上,因此,本发明实施例中还可以通过设置开关阵列1032中多个切换开关不同时与电容或者电感连接,即开关阵列1032中的切换开关仅一部分与电容或者电感连接,此时,开关阵列1032仍可以保证毫米波天线正常通信,且,此时2G、3G和4G天线通过切换开关1031也处于通信状态,因此,本发实施例中,可以通过开关 单元对天线系统进行调谐,以及保证移动终端可以实现2G、3G和4G天线以及毫米波天线同时进行通信,从而满足了客户的多种需求,提高了客户的体验度。
进一步的,为了实现天线系统的通信功能,本发明实施例中移动终端还包括处理器和收发单元;其中,天线系统的开关单元与收发单元连接,收发单元连接至处理器。
具体地,图6示出了本发明实施例提供的另一种移动终端的结构示意图,如图6所示,该移动终端包括处理器30、收发单元40、开关单元和金属边框,以及设置在金属边框上的毫米波天线对应的缝隙天线阵列。其中,收发单元用于接收或者发出电磁波,开关单元用于控制毫米波天线对应的缝隙天线阵列的扫描角度,以及对金属边框进行孔径调谐,金属边框与设置在金属边框上的毫米波天线对应的缝隙天线阵列和2G、3G和4G天线也构成通信信号的收发天线结构,从而实现移动终端的天线系统实现2G、3G和4G天线以及毫米波天线同时进行通信,以及实现调谐作用,从而满足了客户的多种需求,提高了客户的体验度。
此外,如果上述开关阵列1032中的切换开关全部没有与电容或者电感连接,即开关阵列1032中的切换开关全部处于工作状态,此时,如果毫米波天线对应的天线馈点接收的电磁信号具有相同的相位,则毫米波天线的辐射方向为毫米波天线对应的缝隙天线阵列的法向方向。在实际应用中,如果想毫米波天线对应的缝隙天线阵列具有其他的扫描方向,则可以通过控制移相器来改变毫米波天线对应的天线馈点处的电磁信号的相位来实现,也可以通过控制开关阵列中多个切换开关的状态来实现,因此,上述移动终端还包括移相器,其中,移相器设置在收发单元与开关单元之间,用于调整毫米波天线的相位,以控制毫米波天线的扫描角度。
此外,上述收发单元为RF(RadioFrequency,射频)前端收发机,该RF前端收发机可以实现2G、3G和4G天线以及毫米波天线的通信信号的接收和发送。因此,该RF前端收发机分别与开关单元中与基础天线的天线馈点连接的切换开关1031和与毫米波天线的天线馈点连接的开关阵列1032连接,用于实现2G、3G和4G天线以及毫米波天线的通信信号的接收和发送,从而实现移动终端满足2G、3G和4G天线以及毫米波天线的通信功能,以及实现2G、3G和4G天线以及毫米波天线同时通信的功能,从而满足用户的多种通信需求,提高了用户的体验度。
具体地,图7中还示出了移相器50,设置在RF前端收发机和开关单元之间,其中,移相器的一端与RF前端收发机连接,移相器的另一端则与开关单元中与毫米波天线的天线馈点连接的开关阵列1032连接,由于移相器可以对电磁波的相位进行调整,因此,本发明实施例中可以通过移相器控制毫米波天线对应的缝隙天线阵列的扫描角度,从而实现天线系统中毫米波天线的通信功能。
具体地,在图7中,与基础天线的天线馈点连接的切换开关1031和与毫米波天线的天线馈点连接的开关阵列1032分别用来对基础天线和毫米波天线进行调谐,通常,切换开关1031用于对基础天线进行阻抗调谐,由于切换开关1031可以有多种状态,这样当切换开关1031处于不同的状态时,用于2、3、4G通信的基础天线就可以对应不同的band(频段)状态。但是仅靠切换开关1031来调节阻抗并不能覆盖所有的band状态,这时可以使用开关阵列1032对边框进行孔径调谐。开关阵列1032的组成可以是8个两路单刀单掷开关也可以是四路单刀单掷开关,可以根据具体的使用需求进行选择。假如使用单刀双掷开关,开关的两路一个可以和移相器连接,另一路就可以接匹配电路(电容或者电感),开关阵列1032可以有8个开关,这样就可以有至少8种状态对边框进行孔径调谐,如果是四路单刀单掷开关则有更多调谐状态。
由于毫米波天线和基础天线共用边框,既要保证基础天线工作,也要保证毫米波天线阵列的正常工作,这样8路开关不可能同时处于接匹配的状态,折中使其中0-2个开关处于接匹配状态,并不会导致毫米天线无法正常工作。假如没有开关接匹配状态,那么就是有8个毫米波天线的天线馈点在工作,如果到达天线馈点阵列单元馈电信号有着相同的相位,那么此时辐射方向为毫米阵列的法向方向。如果想毫米波天线有其他的扫描方向,一方面可以通过控制移相器改变毫米波天线的馈电信号相位来实现,另一方面也可以通过控制开关阵列的通断来实现。由于可以通过这两种方式实现波束扫描,使得本发明实施例中移动终端的天线系统有更多的扫描角度以及范围。
在实际使用时,可以根据情况选择天线馈点和开关阵列的数量,并不局限为8个。为了便于理解,图8示出了一种仿真结果示意图,其中,图8中的仿真结果是以天线馈点为1×6阵列进行仿真得到的,此时,对应的开关阵列也是由6个切换开关组成,毫米波频段选择28GHz。其中图8是毫米波阵列单元的S11参数,图9是毫米波天线的天线馈点阵列的方向图,从图9中可以看出,毫米波天线的天线馈点阵列的方向图是向上的,这样更加有利于接收信号。
进一步,当移动终端的金属边框作为基础天线频段的天线,即作为2G、3G以及4GHz频段的天线时,其仿真结果如图10和11所示,其中,图10中为低频,以及部分中高频频段的S11参数,图11是部分中高频频段的S11参数,由图10和图11可以看出,随着5Gsub-6Ghz频段的应用,本发明实施例中包括基础天线和毫米波天线的移动终端的天线系统可以在满足毫米波天线的情况下,同时满足2G、3G、4G以及sub-GHz频段的需求。
在上述实施例的基础上,本发明实施例还提供了一种天线系统的切换方法,该天线系统的切换方法应用于上述实施例中的移动终端,图12示出了一种天线系统的切换方法的流程图,如图12所示,该方法包括:
步骤S102,监测移动终端当前所处的网络环境。
步骤S104,根据网络环境触发移动终端的天线系统的开关单元,以通过开关单元对天线系统进行调谐。
