天线辐射的是无线电波，接收的也是无线电波，因此具有一定的范围性和方向性。在生产制造移动设备的时候，天线被固定在设备内部，因此也就使其信号传输范围和方向得到了确定。在通信基站尚未完全普及的偏远地区，例如我国中西部地区的农村地区以及人烟稀少的高原、荒漠地区，通信设备往往跟随用户移动很容易就处于信号强度较弱的处境中。这种情况下，天线的接收能力就会降低，从而影响到移动设备的正常使用。除上述缺陷外，天线模块固定设置的方式也对后期的维护检修带来一些不便。
受限于通信设备的大小，现有的天线装置均无法通过自我调节来提升接收能力。

附图说明

具体实施方式
下面结合附图对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
如图1和2所示，一种天线装置，包括定壳体1、动壳体2、间隙调节装置3、若干天线本体3和信号收发电路6。
定壳体1用于为其它部件提供安装基础和保护作用，其整体形状为扁平的长方形盒体。定壳体1内设有若干导向槽12，相应地，动壳体2朝向定壳体1的一侧设有若干导向件21，导向件21插入对应导向槽12内形成滑动连接，同时使动壳体2与定壳体1之间形成一定的间隙8，动壳体2的厚度与定壳体1相同。作为优选，导向件21为杆状或条状结构体，其目的是防止动壳体2与定壳体1之间形成偏移，从而能够沿直线移动。定壳体1远离动壳体2的一端设置有接口9。接口9用于与无线通信设备的主板接口相连，其不仅实现该天线装置与无线通信设备之间的信号交互，而且还具有从主板取点实现供电的作用。
间隙调节装置3设置于定壳体1内，其活动端连接动壳体2以改变间隙8的大小。天线本体3的长度各不相等并对应不同的信号波长，天线本体3设置在动壳体2内，作为优选，天线本体3以注塑方式嵌入在动壳体2里。
信号收发电路6为常规电路，可以接收和发送信号，并且检测信号强度。信号收发电路6设置于丁壳体1内，信号收发电路6通过伸缩导线4分别连接信号收发电路6以收发信号，通过第一导线7连接间隙调节装置3以使间隙调节装置根据信号收发电路6检测到的信号强度驱动动壳体2相对定壳体1移动而改变间隙8的大小，通过第二导线10连接接口9。
如图2所示，在初始状态下，动壳体2与定壳体1的距离较近，此时间隙8较小， 也即H1较小，这个状态下天线装置仅能接收强度较大的信号，一旦周围环境中的信号强度下降，则就会影响整个天线装置200接收信号的能力。因此在该情况下，信号收发电路6根据信号强度发出控制信号给间隙调节装置3，间隙调节装置3启动，并驱动动壳体2逐渐远离定壳体1，这个过程中间隙8逐渐变大，也即H2大于H1，如图1所示。此时净空也就变大，天线本体3形成的辐射体越大，接收信号的能力也就随之提高，从而满足在该环境下有效收发信号的要求。当环境信号强度增强后，间隙调节装置3再将动壳体拉回到，从而缩小净空，此时天线本体3形成的辐射体足够正常接收信号，实现信号的收发。由于定壳体1的另一端设有接口9，因此该天线装置可以作为独立的无线模块接入到其它需要远程信号收发的设备中，这样就实现了小型化和模块化的应用，扩展了适用范围。
作为优选例，定壳体1内设有导线收容槽13，伸缩导线4位于定壳体1内部的部分一一对应收容于导线收容槽13内。每次动壳体2移动的时候，伸缩导线4就会随之伸长或缩短，当缩短时就可能与定壳体1其它部件发生干涉从而纠缠在一起而影响其伸长，为此通过将其收纳于特定的导线收容槽13中从而防止其与其它部件发生干涉。
作为优选例，定壳体1上朝向动壳体2的一侧还设有限位块11。作为优选例，定壳体1上朝向动壳体2的一侧的两端各设置一个限位块11。限位块11的作用在于使定壳体1和动壳体2之间始终保持一定间隙8，从而形成净空。当动壳体2与限位块11接触时，动壳体2与定壳体1之间距离最近，间隙8最小，此时为初始位置。
作为优选例，动壳体2相对定壳体1移动的最大距离小于伸缩导线4的最大伸长长度。这样做的目的在于，当动壳体2处于最远位置时，伸缩导线4仍然还可以继续伸长，如以此来便避免在动壳体2移动的过程中将伸缩导线4拉断或影响到其极限行程，确保净空的最大化。
作为优选例，间隙调节装置3包括电机31、丝杠33和丝杠螺母32；电机31固定在定壳体1内，丝杠33转动设置与定壳体1内并且连接电机31的转轴，丝杠螺母32与丝杠33螺纹连接，并通过连接杆5连接动壳体2。电机31为微型电机，从而将该天线装置的尺寸做的足够小而可以应用于更小的便携设备中。
作为优选例，动壳体2的宽度尺寸不大于定壳体1的宽度尺寸。
作为优选例，天线本体3的数目为三个，且在动壳体2的宽度方向依次分布，靠近两端的天线本体3的长度小于中间的天线本体3的长度。这样做的目的是能够保证在不同频段的信号都能够正常的收发。
如图3所示，基于同样的发明构思，本发明还通过了一种无线通信设备，包括设备本体100和设置于设备本体100内的天线装置200。天线装置200包括定壳体1，动壳体2，间隙调节装置3，若干天线本体3和信号收发电路6。
定壳体1内设有导向槽12；动壳体2朝向定壳体1的一侧设有导向件21，导向件21与导向槽12形成滑动连接并使动壳体2与定壳体1之间形成一定的间隙8，定壳体1远离动壳体2的一端设置有接口9，接口9与设备本体100的主板通信接口相连；间隙调节装置3设置于定壳体1内，其活动端连接动壳体2以改变间隙8的大小；天线本体3的长度各不相等并对应不同的信号波长，天线本体3设置在动壳体2内；信号收发电路6设置于丁壳体1内，信号收发电路6通过伸缩导线4分别连接信号收发电路6以收发信号，通过第一导线7连接间隙调节装置3以使间隙调节装置根据信号收发电路6检测到的信号强度驱动动壳体2相对定壳体1移动而改变间隙8的大小，通过第二导线10连接接口9。
作为优选例，定壳体1为设备本体100的一部分。
作为优选例，设备本体100为笔记本电脑、平板电脑、移动式工控机、移动电话、车载电脑等具有数据无线传输需求的设备。
以上仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本发明的保护范围。
