Description

适用于穿戴式设备的无线电通讯天线及穿戴式设备
技术领域
本发明涉及无线通讯产品领域，尤其是指一种适用于穿戴式设备的无线电通讯天线及穿戴式设备。
背景技术
“穿戴式设备”是一种以应用在人体，以穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。随着科技的发展，时下穿戴设备已越发的智能化，穿戴式设备也从通常的需要依附其他产品渐渐成为一个独立，可不依赖外接设备实现完整或者部分的功能的产品，例如各类进行体征监测的智能手环、智能首饰等。且近些年来，互联网的迅猛发展也对智能的穿戴式设备的形态与应用热点产生了深远的影响，穿戴式设备不再是孤立的一个产品，更多时候其被赋予了联网协同，甚至直接接入互联网的需求。而为了实现上述目的，无线通讯必不可少，无线通讯的基础则在于通讯天线。
然而，众所周知的，由于天线的特性，其产品裸露放置在空间( 以下称：自由空间)中与依附与人体时的特性是截然不同的。而穿戴式设备的天线无疑面临需要同时支持穿戴与自由空间下的正常工作的需求，特别是穿戴时，设备中天线往往会大面积的贴敷在人体上，因此这对天线设计提出了很高的要求。为此行业亟需合适完善的天线解决方案以满足穿戴式设备迅猛发展的需求。
发明内容
本发明所要解决的技术问题是：提供一种在穿戴人体及自由空间下皆可良好工作的无线电通讯天线及穿戴式设备。
为了解决上述技术问题，本发明采用的技术方案为：一种适用于穿戴式设备的无线电通讯天线，包括呈弧状的天线主体，所述天线主体包括依次相连的第一天线板，基板及第二天线板，第一天线板与第二天线板相向弯折至基板一侧表面且与基板表面相平行，所述第一天线板及第二天线板与基板的间距小于8mm；所述第一天线板与第二天线板间设有间隙；所述第一天线板及第二天线板相对一端的边沿分别设有第一馈电端及第二馈电端；所述第一天线板于连接基板一端的边缘设有调节单元电连接所述基板。
本发明的有益效果在于：基于穿戴应用的需求，特别是腕部的穿戴需求，将无线电通讯天线主体设计成为弧状，并配置间隔的低频天线及高频天线，以满足WIFI、GPS以及移动通讯信号传输需求，同时，低频天线、高频天线分别接入一个基板，该基板作为地并承担贴附人体的介质，从而将佩戴于人体时的影响降到最低。此外通过馈电端位置、调节单元位置以及低频天线及高频天线的间隙位置的配置，使得天线的特性得以方便快捷的调整，满足不同穿戴设备应用的需求。
附图说明
下面结合附图详述本发明的具体结构
图1为本发明的结构示意图；
图2为本发明的应用结构示意图。
1-第一天线板； 2-第二天线板； 3-调节单元； 4-第一馈电端； 5-第二馈电端； 6-间隙； 10-设备主体； 20-人体组织。
具体实施方式
为详细说明本发明的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
对比普通的天线设计（例如上面提到的手机中天线的设计），其结构构思都是采用平直的天线结构，该种结构在一个手机中可以很好的得到应用。在本专利中，天线需要弯曲且围绕佩戴在有损耗介质（在穿戴设备中主要指的是人体组织20）上，其天线与有损耗介质间的距离通常在整个弧线范围内仅有0-3mm，这较之通常设备（如移动电话或其他移动设备）而言是不同的天线环境，因此这也导致了天线设计在穿戴式设备中与移动电话中的本质差异，即两者应用环境与设计概念均不相同，因此这也是穿戴式设备中天线设计一大难点所在。
为此，本发明最关键的构思在于：基于穿戴应用的需求，特别是腕部的穿戴需求，将无线电通讯天线主体设计成为弧状，并配置间隔的低频天线及高频天线，以满足WIFI、GPS以及移动通讯信号的接收与发送需求，同时，低频天线、高频天线分别接入一个基板，该基板作为地并承担贴附人体的介质，从而将佩戴于人体时的影响降到最低。此外通过馈电端位置、调节单元位置以及低频天线及高频天线的间隙位置的配置，使得天线的特性得以方便快捷的调整，满足不同穿戴设备应用的需求。
请参阅图1以及图2，本发明涉及一种适用于穿戴式设备的无线电通讯天线，包括呈弧状的天线主体。所述天线主体包括依次相连的第一天线板1，基板及第二天线板2，第一天线板1与第二天线板2相向弯折至基板一侧表面且与基板表面相平行，且第一天线板及第二天线板与基板的间距小于8mm。所述第一天线板1与第二天线板2间设有间隙6，所述第一天线板1及第二天线板2相对一端的边沿分别设有第一馈电端4及第二馈电端5；所述第一天线板1于连接基板一端的边缘设有调节单元3电连接所述基板。
从上述描述可知，本发明的有益效果在于：基于穿戴应用的需求，特别是腕部的穿戴需求，将无线电通讯天线主体设计成为弧状，并配置间隔的低频天线及高频天线，以满足WIFI、GPS以及移动通讯信号传输需求，同时，低频天线、高频天线分别接入一个基板，该基板作为地并承担贴附人体的介质，从而将佩戴于人体时的影响降到最低。此外通过馈电端位置的设置以及调节单元的位置配置与调整，可调整天线的所需要的工作频率，从而使得本产品可满足不同穿戴设备的应用需求。
实施例1：
上述结构中，申请人通过对天线模拟设计并结合后续大量的测试、调整后，得出第一天线板1及第二天线板2与基板的间距为1.5-5mm为最佳。由此，较之普通移动通讯领域例如手机中应用的厚度大于8mm的天线而言该天线具备非常薄的优点（甚至可以小于3mm）。而类似的手机天线却要厚8毫米以上，由于此类天线是被用来在一个完全填充的手机中的，因此在封闭所有的手机配件（电池，印刷电路板，扬声器等）下天线有足够的位置。
而穿戴设备中则不同，因此本专利的天线仅有手机类天线小于一半厚度，特别适合在穿戴设备中应用。
实施例2：
上述结构中，申请人通过对天线模拟设计并结合后续大量的测试、调整后，得出第一天线板及第二天线板的间隙为1-5mm。
实施例3：
上述结构中，最佳的第一天线板被设计为低频天线，且本实施例中其长度长选择为低频频率的1/4波长长。这里说的低频，为700MHz-960MHz的频率段，通常应用于 GSM通信频段以及支持GPS信号的传输。
实施例4：
上述结构中，对应的第二天线板设计为高频天线，且本实施例中其长度长选择为高频频率的1/4波长长。此处说的低频，为1800MHZ - 2300MHz的频率段，通常应用于高频移动通讯及WIFI(无线网络)信号的传输。
实施例5：
上述结构中，申请人通过对天线模拟设计并结合后续大量的测试、调整后，得出天线主体的弧状半径为25-35mm。
实施例6：
上述结构中，申请人通过对天线模拟设计并结合后续大量的测试、调整后，得出所述天线主体的宽度为5-40mm。
可见，本专利中天线主体的宽度可适用于较窄的结构。比较移动电话中应用的天线通常需要100×50×8毫米的尺寸。50mm的宽度明显对于人体佩戴（特别是手腕佩戴）明显会太宽，难以符合工业设计以及人们佩戴使用的美观需求。而采用本专利天线结构，经申请人大量实验正式天线主体的宽度可在5-40mm较宽的范围内得以应用。 完全符合穿戴式设备应用环境的需求。
本发明还涉及一种穿戴式设备，包括设备主体以及上述适用于穿戴式设备的无线电通讯天线。
从上述描述可知，本发明的有益效果在于：其设计上从穿戴式设备的应用的需求出发，天线厚度薄，并适应成为弧状，且配置了低频天线及高频天线可满足WIFI、GPS以及移动通讯信号传输需求，同时，低频天线、高频天线分别接入一个基板，该基板作为地并承担贴附人体的介质，从而将佩戴于人体时的影响降到最低。此外通过馈电端位置、调节单元位置以及低频天线及高频天线的间隙位置的配置，使得天线的频率响应得以方便快捷的调整，满足不同穿戴设备应用的需求。
实施例1：
上述结构中，所述设备主体10设置于第一天线板1外表面，且设备主体10不覆盖所述第一天线板1与第二天线板2间的间隙6。
由于此处间隙6起到第一天线板1与第二天线板2的隔离作用，因此设备主体10设置时，以不覆盖间隙6为最佳。
综上所述，本发明提供的适用于穿戴式设备的无线电通讯天线及穿戴式设备，设计时充分基于穿戴应用的需求，通过将无线电通讯天线主体设计成为弧状，并配置间隔的低频天线及高频天线，以满足WIFI、GPS以及移动通讯信号的接收与发送需求，同时，低频天线、高频天线分别接入一个基板，该基板作为地并承担贴附人体的介质，从而将佩戴于人体时的影响降到最低。再者通过馈电端位置的设置以及调节单元的位置配置与调整，可快速调整天线的频率响应，从而使得本产品可满足不同穿戴设备的应用需求。此外，整个天线的厚度、宽度的尺寸上远小于传统手持设备的天线，特别适合在穿戴设备中应用。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，例如，稳重的第一、第二……只代表其名称的区分，不代表它们的重要程度和位置有什么不同。同样的，上、下、左、右、前、后只代表其相对位置而不表示其绝对位置。因此，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
