Description

一种滑盖型移动通信终端的电流型天线 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板上或与其相连接 的电流型天线。 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。滑板由上下两块滑动板和驱动装置（ actua tor )组成。驱动装置（ac tuator) 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)或在一块接地 板（ground )挖出特定的形状的沟槽 (slot/slit), 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， 本发明提供了一种滑盖型移动通信终端的电流型天线。 一种滑盖型移动通信终端的电流型天线， 由滑动板， 电流型天线组成， 在滑动板（ 1 )或者滑动板（ 2 )上有， 或者和滑动板（ 1 )或滑动板（ 2 )连 接有， 由导电材料构成的一个或一个以上的电流型天线（3 )并且电流型天线 ( 3 )和移动通信终端的电路板 ( 4 )相互电连接。

作为本发明的一种优选方式， 所述电流型天线 3可位于滑动板 1或者 2的 侧边和两端。 有益效果：
由于天线和滑板成一体或连接成一体， 和滑板共用一个空间，从而实现了 移动通信终端的小型化和超薄化， 同时也减少生产中的组装成本。 附图说明

图 5为天线通过导电弹脚和电路板电连接的一种连接方式的示意图。 图 6为天线通过导电弹脚和电路板电连接的另一种连接方式的示意图。 具体实施方式
下面结合附图详细说明：
在图 1和图 2中， 滑动板 1和滑动板 2为上下两块滑动板， 两块滑动板 滑开后就如图 1所示， 合拢后就如图 2所示。
如图 3 , 图 5和图 6所示， 一种滑盖型移动通信终端的电流型天线， 由滑 动板， 电流型天线组成， 在滑动板（1 )或者滑动板（2 )上有， 或者和滑动 板（ 1 ) 或滑动板（ 2 )连接有， 由导电材料构成的一个或一个以上的电流型 天线（ 3 )并且电流型天线（ 3 )和移动通信终端的电路板 ( 4 )相互电连接。
在滑动板 1或者滑动板 2上， 都可以形成由导电材料组成的形状不同的 电流型天线。 天线 3在图 3中用斜线区域所示。 天线可能在位于滑动板 1上 面， 也可能在滑动板 2 上面。 可以位于滑动板的四周， 中心， 顶部， 底部， 总之任意区域。 也可以不在滑动板上， 但是和滑动板相连接。 连接方式可以 多种。 连接的部位也可以多种。 包括和滑板边缘连接， 和滑板中间连接， 和 滑板的顶部底部连接。 根据具体的应用， 天线形状也可以不同。 天线的形状 可以不同， 可以为圓形， 矩形， 方形， 多边形或者其他形状。 天线数量也可 以为一个， 或者一个以上。
电流型天线 3可以与滑动板 1或者滑动板 2—体或者和其连接。
电流型天线 3可以与滑动板 1或者滑动板 2形成一个整体。电流型天线 3 可以和滑动板一体制造， 成为滑动板的一个延伸部分， 此时电流型天线 3 可 以和滑动板形成一个整体。 电流型天线 3也可以和滑动板分别制造， 然后与 滑动板 1或者 2连接， 比如通过注塑等， 与滑板形成一个整体。
图 3中所示意的就是电流型天线 3和滑动板 1一体制造， 其中电流型天 线 3为图中斜线区域所示， 成为滑动板 1的延伸部分。
电流型天线 3可以通过注塑与滑板 1或者滑板 2连接。
为了加强天线部分的机械强度， 可选择对天线部分区域进行注塑。 注塑 以后的天线和滑动板的连接更加稳固。 在图 4中示意了注塑部分 6。
电流型天线 3可以是平面的也可以是三维曲面的。
如图 4 所示， 天线的形状不单单可以是二维平面型的， 也可以是三维曲 面的。
如图 5和图 6所示， 电流型天线 3和电路板 4通过导电弹脚 5电连接。 电流型天线和电路板电连接的方式很多， 这是一个例子，使用导电弹脚 5
(spring leg or clip)来连接电流型天线 3和电路板 4。
如图 5显示， 导电弹脚 5的一脚固定于天线 3上， 另外一脚和电路板 4 的相应点电连接。
导电弹脚 5的一脚固定于电流型天线 3上， 另外一脚即导电弹脚 5的自 由脚和电路板 4的相应点电接触， 从而实现信号传输。 如图 6显示， 导电弹脚 5的一脚固定于电路板 4上， 另外一脚和电流型天 线 3的相应点电连接。
导电弹脚 5的一脚固定于电路板 4上， 另外一脚即导电弹脚 5的自由脚 和电路板 4的相应点电接触， 从而实现信号传输。
电流型天线 3可位于滑动板 1或者 2的侧边和两端。
原因是位于侧边和两端的天线辐射效率比较高， 因为屏蔽较少。 在图 3和 图 4中示意了两个位于滑动板顶端的天线。 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。
