Description

一种集成于滑盖型移动通信终端的缝隙天线
技术领域
本发明主要涉及一种集成于滑盖型移动通信终端的滑动板上或者与其连 接的缝隙天线。 背景技术
移动通信终端是指可以在移动过程中进行语音或者数据等双向传输的 便携式装置， 比如手机， PDA等。 从外型看这类主要有三类， 即： 直板型， 翻盖型和滑盖型。 滑盖型移动通信终端一般通过滑板（s l ide hinge)实现开合， 从而方便 用户。 滑板（s l ide hinge)由上下两块滑动板和驱动装置（actuator )组成。 驱动装置（actuator)主要由弹簧和支撑架构成。 支撑架连接两块滑动板， 从 而通过弹簧驱动滑动板相向滑动， 实现终端的开合功能。 天线在移动通信终端的作用是将电路板产生的射频信号发射出去和将 接收到的射频信号传给电路板， 以此来实现语音信号， 视频信号和数据等的 无线双向传输。 天线一般由导电物质形成特定的形状（pat tern)或在导电物 质上开出特定形状的沟槽（Slot/slit )形成， 通过恰当的馈电方式和电路板进 行信号传输， 从而有效地发射和接收射频信号。 天线依其辐射机理， 可分为电流型天线和磁流型天线。 电流型天线的 原理为天线的形状（pat tern)由导电体形成， 通过馈源对其激励， 其辐射由 导电体上的电流所决定。 磁流型天线通常为缝隙天线或环形天线， 其原理为 在由导电体组成的地板（ground plane )上开槽， 天线的形状由沟槽的形状 决定， 通过馈源对其激励， 其辐射由沟槽中的等效磁流所决定。 随着技术的发展和用户的需求，现在的移动通信终端不仅仅是收发语音 信号的装置， 而且具有数据通信和多媒体功能， 比如无线互联网 （WLAN ), 蓝牙 （Bluetooth) , 卫星定位 （GPS)， 以及手机电视等功能。 因此需要在移 动通信终端中安装多个天线以发射和接收承载相应信号的电磁波。 目前大部分移动通信终端都采用置于终端内部的内置天线， 因为天线 的尺寸是和频率相关的，所以它必须要有一定的尺寸和高度才能有足够的辐 射效率保证有效地发射和接收电磁波，导致天线是移动通信终端中最大的元 件之一。 在现有的滑盖型移动通信终端中， 天线通常是作为一个独立部件， 安装于终端中。 为了满足多种通信需求， 有时候需要安装多个天线， 而每个 天线需要在移动通信终端中预留出天线的空间， 这样就和移动通信终端的小 型化和超薄化的发展趋势相矛盾。 发明内容
针对以上问题， 本发明提供了一种集成于滑盖型移动通信终端的缝隙天 线。 一种集成于滑盖型移动通信终端的缝隙天线， 由滑动板， 缝隙天线， 天 线接地端和馈电端组成， 在滑动板的内部任意位置有， 或外部连接有， 由导 电材料构成的内部有任意沟槽形状的一个或者一个以上的缝隙天线，缝隙天 线的接地端和移动通信终端的地电连接， 天线馈电端位于沟槽边缘并和移动 通信终端电路板电连接。
作为本发明的一种优选方式， 所述缝隙天线可以是平面二维的， 也可以 是三维曲面的。
作为本发明的一种优选方式， 所述缝隙天线的馈电端和接地端由沟槽相 隔。
作为本发明的一种优选方式， 所述缝隙天线和滑动板的连接可以是滑动 板边缘的延伸成为缝隙天线的一部分。
作为本发明的一种优选方式， 所述缝隙天线可位于滑动板的非导轨部分 的任意位置。
作为本发明的一种优选方式， 所述缝隙天线内部的沟槽形状是任意的， 可以有缺口， 也可以无缺口。 有益效果：
由于天线和滑板共用同一区域， 因此缩小了天线的空间， 实现了移动通 信终端的小型化和超薄化。 附图说明

缝隙天线可以是平面二维的， 也可以是三维曲面的。
如图 4所示， 缝隙天线 3并非平面的， 可以转角， 曲面， 并且沟槽也可 开在该曲面上的任意地方。

缝隙天线和滑动板的连接可以是滑动板边缘的延伸成为缝隙天线的一 部分。
如图 3和图 4 , 滑动板 2边缘可以一直延伸， 从而形成缝隙天线的一部 分。 如果滑动板是导电的， 则直接构成了缝隙天线的接地端。 如果不是， 可 以附着或者加入导电材料等方法从而构成缝隙天线。
如果滑动板是导电的， 也可以直接在滑动板上开槽， 槽的一边的馈电点 和电路板电连接， 另一边的接地点和电路板上的地电连接。
缝隙天线可位于滑动板的非导轨部分的任意位置。
如图 5显示， 缝隙天线位于滑动板的非导轨部分的顶部， 可以提高接受 发送的效率。 导轨就是两快滑动板的滑动导轨。
缝隙天线内部的沟槽形状是任意的， 可以有缺口， 也可以无缺口。
沟槽形状是由天线接收传送信号的性质等条件决定的。 以上所述仅为本发明的较佳实施例而已， 并不用于限制本发明。 凡在本发明 的精神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发 明的保护范围之内。
