附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本申请第一实施例提供的电子装置的结构示意图。
图2是图1所示的微缝带与开关电连接的放大示意图。
图3是本申请第二实施例提供的电子装置中，微缝带与开关电连接的放大示意图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中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申请的一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本申请保护的范围。
如图1所示，本申请实施例提供了一种电子装置10，电子装置10包括但不限于手机、掌上电脑、平板电脑等电子产品。电子装置10具有金属壳体(图未标)和至少一开关13，电子装置10内部设有匹配电路15和射频电路16。本实施例中为了描述简洁，在附图中略去了电子装置10内部的其他组件。所述金属壳体和至少一开关13实质上形成了壳体天线。所述壳体天线即为使用所述金属壳体充当天线辐射体，并配合至少一开关13，以实现拓展天线的低频带宽的一种天线。下文还将详细描述所述壳体天线。
如图1和图2所示，所述金属壳体的周缘具有周边框11，所述周边框11上设有至少一个微缝带12，所述至少一个微缝带12将所述周边框11分割成至少一段框体101，所述微缝带12由至少两条间隔排列的微缝113形成，相 邻两条所述微缝之间具有金属部114。
所述开关13包括第一端131及第二端132，所述第一端131电连接至所述微缝带12分割出的所述框体101，所述第二端132电连接至所述金属部114，其中，所述至少一个微缝带12分割形成的至少一段框体101均为一个独立天线。所述独立天线是指，在经过配置后，能辐射某种频率的射频信号的天线辐射体。例如，所述独立天线可以是GPS天线、蓝牙天线、WIFI天线或NFC天线的天线辐射体。
具体的，如图1所示，周边框11上设有四个微缝带12。每两个微缝带12形成一段作为独立天线的框体101，该框体101至少包括第一框体111以及第二框体112。匹配电路15位于射频电路16与第一框体111之间，且与射频电路16及第一框体111电连接。匹配电路15用于匹配天线的阻抗，以降低由于阻抗失配造成的回波损耗。在其他实施例中，微缝带12的数量根据实际需求确定。例如，微缝带12的数量还可以为1个、2个或者3个。
如图2所示，微缝带12由至少两条间隔排列的微缝113形成，相邻微缝113之间具有金属部114。本实施例中，以微缝113为4条、金属部114为3个为例进行描述。在其他实施例中，微缝113或金属部114的数目不限于此，而是根据具体的设计需要确定。
本实施例中，微缝带12的宽度为1.5mm～5.0mm，微缝带12中各条微缝113的宽度为0.05mm～0.3mm，且微缝113为等距离间隔排列。微缝113等距离间隔排列的方式易于加工。在其他实施例中，微缝带12与微缝113的宽度根据具体的设计需要及工艺精度确定，和/或微缝113为不等距离间隔排列。
如图2所示，开关13包括第一端131与第二端132。开关13的第一端131与第一框体111电连接，第二端132与微缝带12中的一个金属部114电连接。当开关13闭合时，等效的天线长度加长，第一框体111的天线的谐振频率降低；当开关13断开时，等效的天线长度变短，天线的谐振频率相比较开关13闭合时提高。而天线的谐振频率发生变化，其低频带宽也随之变化。由此，通过开关的闭合或断开状态，便可获得不同的低频带宽，即拓展了低频带宽，也增加了天线性能调试的自由度。本实施例中，开关13为单刀单掷开关，开关13的第二端132只能电连接至一个金属部114，因此只能拓展一种低频带宽。
如图3所示，在本申请第二实施例中，与上述第一实施例不同的是，开关14为单刀双掷开关，开关14包括2个第二端142。开关14的2个第二端142分别电连接至两个不同的金属部114。本实施例中，通过开关14的不同开关状态，能够拓展两种低频带宽。在其他实施例中，所述开关可以为其他类型的单刀多掷开关，例如，所述开关为单刀三掷开关。所述开关包括多个所述第二端，多个所述第二端可以分别电连接至更多不同的金属部114，由此可以进一步拓展低频带宽，以及进一步增加天线性能调节的自由度。
进一步的，在上述实施例中，所述开关13或14与金属部114之间还连接有电感或电容元件。设置电感或电容能够进一步方便天线性能的调节。
在其他实施例中，所述开关13或14的个数可为其他数目，例如为两个，第一框体111通过一开关13或14与一相邻的微缝带12的其中一个或多个金属部114电连接，第二框体112通过另一开关13或14与另一相邻的微缝带12的其中一个或多个金属部114电连接。从而，不同的天线都能通过开关进行天线性能的调节及拓展。
其中，该第一框体111可为GPS天线，第二框体112可为WIFI天线。该四个微缝带12分割形成的其余两个框体可为蓝牙天线、NFC(近场通信)天线等。
因此，本申请的电子装置，通过在所述金属壳体的周边框上设置包括至少两条间隔排列的微缝的微缝带，以将所述周边框分割出作为独立天线的至少一段框体和位于相邻所述微缝之间的金属部，使所述开关的两端分别电连接至所述框体和所述金属部。当所述开关的开关状态变化时，天线的等效长度发生变化，天线的谐振频率随之变化，从而能够获得不同的低频带宽，由此拓展了电子装置天线的低频带宽，增加了天线性能调试的自由度。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
