共用射频同轴线缆的蓝牙天线及通信终端 技术领域
本发明涉及一种通信设备, 尤其涉及一种共用射频同轴线缆的 蓝牙天线及通信终端。 背景技术

在蓝牙模块中除了核心的系统芯片外, 天线是影响蓝牙模块传 输特性的关键性组件。 在各种不同的蓝牙应用产品中, 所使用的天 线设计方法与制作材质也不尽相同, 目前最常见的蓝牙天线种类包 括有偶极天线 (Dipole Antenna) 、 PIFA 天线 (Planar Inverted F Antenna) 、 单极子天线 (Monopole Antenna) 以及微小型陶瓷天线 ( Ceramic Antenna ) 等。
随着消费者的需求和制造技术的进步, 移动终端 (如手机、 笔 记本等) 的设计日益短小轻薄。 同时, 无线传输 (包括语音和数据 传输) 已经成为各类移动终端不可或缺的功能。 随着移动终端尺寸 的减小, 同时为了满足不同协议的无线传输, 必须在有限的空间内 设置数个天线装置, 这使得天线的设计愈加困难, 因此如何在尽可 能不降低工作性能的前提下减小天线的尺寸成为移动终端设计的 一个重点。 发明内容
针对上述存在的问题, 本发明的目的是提供一种共用射频同轴 线缆的蓝牙天线及通信终端, 以在尽可能不降低工作性能的前提下 减小天线的尺寸。
本发明的目的是通过下述技术方案实现的:
一方面, 提供一种共用射频同轴线缆的蓝牙天线, 其中: 包括一射频同轴线缆, 所述射频同轴线缆具有第一射频接口和 第二射频接口, 所述射频同轴线缆两端分别与所述第一射频接口和 所述第二射频接口连接;

另一方面, 提供一种通信终端, 其中, 包括如上述任意一项的 共用射频同轴线缆的蓝牙天线。
与已有技术相比, 本发明的有益效果在于:
通过将通信终端上的射频同轴线缆的外导体作为蓝牙天线的 辐射体, 该射频同轴线缆仍然能够用于传输射频信号, 从而达到蓝 牙天线与射频同轴线缆共用的目的, 减小了天线尺寸, 从而达到缩 减整个通信终端体积大小的目的。 附图说明
构成本发明的一部分的附图用来提供对本发明的进一步理解, 本发明的示意性实施例及其说明用于解释本发明, 并不构成对本发 明的不当限定。 在附图中:
图 1 示出了本发明共用射频同轴线缆的蓝牙天线的结构示意 图;
图 2示出了本发明共用射频同轴线缆的蓝牙天线的一段共用射 频同轴线缆的截面示意图;
图 3示出了本发明共用射频同轴线缆的蓝牙天线所形成的驻波 天线原理图。 具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术 方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明 一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本 领域普通技术人员在没有作出创造性劳动前提下所获得的所有其 他实施例, 都属于本发明保护的范围。
需要说明的是, 在不冲突的情况下, 本发明中的实施例及实施 例中的特征可以相互组合。
如图 1所示, 本发明共用射频同轴线缆的蓝牙天线包括一射频 同轴线缆 2,射频同轴线缆 2具有第一射频接口 31和第二射频接口 32, 射频同轴线缆 2两端分别与第一射频接口 31和第二射频接口 32连接。
在优选实施例中, 射频同轴线缆 2设于一 PCB板 1上, 更进 一步的, 射频同轴线缆 2位于 PCB板 1 的表面上的边缘位置。 射 频同轴线缆 2之所以位于 PCB板 1的边缘位置, 原因是一般 PCB 板 1中间都是用于置放电池或其他器件位置, 即使有空余位置, 也 很有可能会被其他表面金属的器件所覆盖而引起效率降低。
射频同轴线缆 2 的总长度为蓝牙谐振波长的四分之一的奇数 倍, 在本发明的优选实施例中, 射频同轴线缆的总长度至少为蓝牙 谐振波长的四分之三。
射频同轴线缆 2上具有一馈电点 4, 继续参看图 1所示, 馈电 点 4距离第一射频接口 31的距离 dl为蓝牙谐振波长的四分之一的 偶数倍, 而馈电点 4距离第二射频接口 32的距离 d2为蓝牙谐振波 长的四分之一的奇数倍。 在本发明的优选实施例中, 馈电点 4距离 第二射频接口 32的距离 d2为蓝牙谐振波长的四分之一, 而馈电点 4距离第一射频接口 31的距离 dl为蓝牙谐振波长的二分之一。
请参看图 2所示, 射频同轴线缆 2的结构由内而外依次为内导 体 21、 内层绝缘体 22、 外导体 23和外层绝缘体 24, 外导体 23上 有两处接地, 在优选实施例中, 外导体 23 分别在与第一射频接口 31的连接处和与第二射频接口 32的连接处接地, 馈电点 4与外导 体 23连接。 在本发明的优选实施例中, 同时参看图 1所示, PCB 板 1为矩形, 第一射频接口 31接近 PCB板 1的角部。 根据传输线理论:
ZL + jZQ tan βΐ
( 1 ) 0 + jZL tan βΐ 其中, ^是输入阻抗, ZQ为无耗传输线的特性阻抗, zz是负
载阻抗 (L表示 Load, 即负载的意思), β = ^~ , 1是长度。 当短路 λ
时, 即 ^ = 0,
Z0 + jZL tan βΐ 当 d2为蓝牙谐振波长四分之一时, 即: 的值将趋向于无穷大, 因此可以看
Figure imgf000008_0001
作是开路。 当 dl 的长度为蓝牙谐振波长四分之一的偶数倍, 假设 此处是两倍, (由两倍可以类推至四倍等), 即长度为蓝牙谐振波长 四分之一的两倍时, 可分解为两个四分之一, 此时射频同轴线缆一 端为接地, 另一端为馈电点。 从中间点看向接地点时, 为并联一无 穷大阻抗即相当于开路, 所以可以简化为馈电点到中间点长度为四 分之一, 中间点再往后为开路的模型。 以上是半波振子的典型, 公 式 (1 ) 中的辐射阻抗可以为 R+ jX, 其中, R表示实部电阻, 而公 式的虚部是电抗 X。
因此, 对蓝牙天线的馈电点 4而言, 第二射频接口 32处接地 短路, 则长度 d2 为蓝牙谐振波长四分之一的这段射频同轴线缆在 蓝牙天线的馈电点 4处相当于开路, 因此不会参与蓝牙天线的电磁 波辐射, 因而不作为蓝牙天线的辐射体。 蓝牙天线从馈电点 4处馈 入信号, 将蓝牙天线馈电点 4到接地射频端口 31 的那段射频同轴 线缆的外导体作为蓝牙天线的辐射体, 该段射频同轴线缆的外导体 长度 dl 为蓝牙谐振波长的二分之一, 形成一个驻波天线, 请参考 图 3, 因而可以在蓝牙标准工作频段 (2.4GHz〜2.5GHz) 产生一个 谐振, 从而基本满足一般通信终端蓝牙天线的辐射性能要求。
本发明通过将通信终端上的射频同轴线缆的外导体作为蓝牙 天线的辐射体, 该射频同轴线缆仍然能够用于传输射频信号, 从而 达到蓝牙天线与射频同轴线缆共用的目的, 减小了天线尺寸, 从而 达到缩减整个通信终端体积大小的目的。
本发明实施例还提供了一种通信终端, 该通信终端设有上述任 一种蓝牙天线, 由于上述任一种蓝牙天线具有上述技术效果, 因此, 设有该蓝牙天线的通信终端也应具备相应的技术效果, 其具体实施 过程与上述实施例类似, 兹不赘述。 以上对本发明的具体实施例进行了详细描述, 但本发明并不限 制于以上描述的具体实施例, 其只是作为范例。 对于本领域技术人 员而言, 任何等同修改和替代也都在本发明的范畴之中。 因此, 在 不脱离本发明的精神和范围下所作出的均等变换和修改, 都应涵盖
