本发明实施例的电子设备中, 通过在作为天线臂的金属部件上形成有用于高频电流传 输的电流传输通道, 使得高频电流在该金属部件上能够通过所述电流传输通道按照预定路 径传输, 以避开用户手掌握持电子设备或是电子设备贴近人体时对处于手掌 /人体附近的天 线的性能带来影响, 提高天线的性能。
本发明实施例的电子设备中, 包括一用于作为天线臂的金属部件, 金属部件上形成有 用于高频电流传输的电流传输通道, 使得高频电流在该金属部件上能够通过电流传输通道
按照预 ¾路径传输。
ώ于有这样的电流传输通道, 因此高频电流在该金属部件上能够通过电流传输通道按 照预定路径传输。
在本发明的具体实施例中, 可以通过多种方式来实现电流传输通道的形成, 本发明实 施例可以应用于通常的天线, 也可以用于利用电子设备的壳体作为天线的情况下, 下面分
<用于通常天线 >
在本发明的具体实施例中, 以倒 F结构这种常用的天线来进行说明。
倒 F型天线是上世纪末发展起来的一种天线, 具有结构简单、 重量轻、 可共形、 制造 成本低、 辐射效率高、 容易实现多频段工作等独特优点, 因此, 近几年来, 倒 F型天线得 到了广泛的应用研究和发展。
由于天线在电子上的形态就类似于一个电感电容电阻组成的电路网络, 其中任一个参 数产生变化, 都会使得整个天线的整体特性产生变化 (如阻抗、 频率、 效率等)。
图 1为贴片对倒 F结构的天线的电流通道的影响情况示意图。 当手(当然还可能是其 他的物体) 位于天线附近或者直接覆盖在天线表面时, 会对天线的整体特性产生变化。 通 常情况下, 如果没有设置该介电常数可控的贴片, 天线的电流通道如图 1所示, 高频电流 会沿着电流通道 1进行传输。 但当手位于天线附近或者直接覆盖在天线表面时, 会对天线 的整体特性产生变化, 导致天线性能下降。
基于以上说明可以知道, 当手 (当然还可能是其他的物体)位于天线附近或者直接覆 盖在天线表面时, 会对天线的整体特性产生变化, 而通过设置具有一定介电常数的贴片同 样也能够对天线的整体特性产生变化。 因此, 在本发明的具体实施例中, 可以通过设置一 介电常数可控的贴片来进行补偿。
该介电常数可控的贴片在通电时, 其介电常数从第一介电常数变化到第二介电常数, 而该贴片的介电常数为第一介电常数时, 对天线性能的影响会很小, 而在贴片的介电常数 为第二介电常数时, 其对天线性能的影响加大, 以弥补由手带来的天线性能下降问题。
在本发明的具体实施例中, 该介电常数可控的贴片在通电时, 其介电常数从第一介电 常数变化到第二介电常数。 此时, 贴片会和手一起改变天线上的电流传输通道, 使高频电 流会改变为沿着电流通道 2进行传输或改变电流通道 1的特性, 弥补 ώ手带来的天线性能 下降问题。
根据本发明的一个实施例, 对于该¾片的第一介电常数和第二介电常数以及位置的确 定, 可以通过实验来确定, 下面就实现过程说明如下。
预先从不同材质的一介电常数可变的贴片中, 选择常规形态下 (没有加电) 不会对天 线性能造成影响的贴片。
选定贴片后, 固定天线被覆盖的部位, 不断调整贴片的位霄、 贴片的激励电流来测试 天线性能, 直至找到天线性能能够满足要求时的贴片的位置和激励电流即可。
最后, 将贴片贴设于找到的位置, 并记录符合要求的激励电流。 在实际应用时, 在检 测到手掌覆盖预定位置时, 为贴片提供记录的激励电流, 即可改变天线的电流通道, 由贴 片来补偿 ώ手带来的天线性能下降。
当然,对于不同的握持位置, 可能需要贴片具有不同的介电常数来补偿。这种情况下, 可以通过改变天线的覆盖部位来重复上述的实验, 以得到不同位置对应的介电常数 (激励 电流)。最后根据实际测试到的覆盖位置来给贴片供应对应的电流, 以补偿由手带来的天线 性能下降。
根据本发明的另一实施例, 也可以通过仿真来找到设置补偿贴片的位置。
另外, 手握持的部位可以通过在天线周围设置压力传感器来实现检测, 在此不详细说 明。
本发明实施例的电子设备中, 在金属部件上形成有用于高频电流传输的电流传输通道 2, 使得高频电流在该金属部件上能够通过 ι¾流传输通道按照预定路径传输, 能够补偿由手 带来的天线性能下降, 提高了天线的性能。
<利用电子设备的壳体作为天线的情况下 > 现有的使用金属或其它导电材料作为外壳的电子设备,为了达到无线收发的效果要求, 一般都是于金属外壳上割开一块电磁净空区域以放置天线。 然而上述设计会极大的影响工 业设计和产品型态, 并使得产品成本增加, 降低结构强度。
为了解决上述问题, 现有技术中利用塑胶与金属一体成型方式来制作外壳, 但这种方 式同样也会增加产品成本, 并使得金属外壳的质感受到极大的影响。
为了解决上述问题, 本发明的具体实施例中, 使用导电壳体来进行无线信号的发送, 降低产品成本, 提高材料质感与机构强度。
本发明实施例的电子设备, 包括一第一壳体、 第一无线通信模块和第一射频线等。 第 一壳体为导电壳体。 第一无线通信模块设置有第一输入接口。 第一射频线, 具有第一端和
第二端。 第一射频线的第一端与第一输入接口电连接。 第一射频线的第二端与第一壳体电 连接。 第一壳体用于作为天线臂, 通过第一射频线与第一无线通信模块进行射频信号的交 可:。
在利用电子设备的壳体作为天线的情况下, 设覽电流通道可以通过两种方式来实现。 图 2为没有贴片时, 导电壳体作天线臂时电流传输的示意图。 当导电壳体的介电常数 一致, 且不附加任何贴片时, 其上的电流传输通道如图 2所示, 会以馈点为中心四处发散。 但应当理解的是, 越靠近壳体边缘的信号越容易向空中扩散。
为了解决导电壳体作为天线臂时的天线性能问题, 在本发明的具体实施例中, 在壳体 的表面贴设介电常数固定的贴片。
图 3为有贴片时, 导电壳体作天线臂时电流传输的示意图。 如图 3所示。 该贴片的介 电常数高于壳体的介电常数。 因此, 电流会被贴片影响, 不再是以馈点为中心向均匀地传 导。 取而代之的是, 电流能量会向比较多的在导电壳体的外围集中, 从而提高了向空间辐 射的效率。
以上是为了提高天线的传输性能。 但在某些情况下, 用户不再考虑传输性能, 而是考 虑其辐射性。 这种情况下, 就要求无线 能少向空中传递。 这也可以通过如图 4所示的贴 片来实现。
图 4为有贴片时, 导电壳体作为天线臂时电流传输的另一示意图。 如图 4所示, 该贴 片的介 ¾常数高于壳体的介电常数。 因此, 电流会被贴片影响, 能够使得尽可能多的电流 能量向壳体的中心集中, 而不是传向外围, 从而减小向空间辐射的能量, 降低了辐射。
上述的第一种方式下, 利用贴片来形成该传输路径。 但应当理解的是, 也可以通过在 壳体的制造过程中使得第一壳体上具有介电常数不同的部位来形成电流传输通道。
以图 3所示的情况为例, 只需要在制造过程中将导电壳体被贴片覆盖的部分使用可控 的介电常数的材料即可。
之前提到, 为了满足更好的天线性能, 需要将电流导向壳体的周围, 而为了减少辐射, 需要将电流导向壳体的中心。 因此, 为了满足不同的需求, 在本发明的具体实施例中, 可 以在第一壳体上形成有多条电流传输通域, 并根据需要导通第一射频线 (馈线) 的第二端 与不同电流传输通道之间的电连接, 以满足不同的需求。
图 5为根据不同需求, 在导电壳体作天线臂时选择不冋路径的示意图。 如图 5所示, ώ贴片形成两条通道, 并设置两个馈点。 需要减少辐射时, ώ导通控制部件导通第一射频
线的第二端与贴片上方的馈点之间的电连接。 在需耍提高天线性能时, ώ导通控制部件导 通第 -射频线的第二端与贴片右边的馈点之问的电连接即可。
对于之前提到的手握持影响天线性能的问题, 本发明实施例的电子设备还包括检测部 件和导通控制部件。
检测部件用于检测第一壳体被握持的部位。 导通控制部件根据检测部件的检测结果, 导通第一射频线的第二端与第一电流传输通道之间的电连接。 第一电流传输通道为多条电 流传输通道中, 除被握持的部位所在的电流传输通道之外的其他电流传输通道。 本发明实施例的电子设备中, 利用电子设备中的导电壳体作为无线发射的天线臂, 并 通过射频线连接无线通信模块和导电壳体, 在无线通信模块和导电壳体间进行射频信号的 交互, 在实现天线功能的同时, 降低产品成本, 提高材料质感与机构强度。 换言之, 如下 图 7-图 12的本发明实施例的电子设备可以单独的用导电壳体作为无线发射的天线臂,并通 过射频线连接无线通信模块和导电壳体, 在无线通信模块和导电壳体间进行射频信号的交 互。 同时也可以在所述导电壳体上形成有用于高频电流传输的电流传输通道, 使得高频电 流在该导电壳体上 (即金属部件) 上能够通过电流传输通道按照预定路径传输。 从而拓宽 单独使用导电壳体作为无线发射的天线臂的天线的频宽。
图 7为本发明实施例的电子设备中, 第一壳体即可作为单极子天线的结构示意图。 如 图 7所示, 本发明实施例的电子设备包括一第一壳体、 第一无线通信模块、 第一射频线等。 第一壳体为导电壳体。 第一无线通信模块设置有第一输入接口。 第一射频线具有第一端和 第二端。 第一射频线的第一端与第一输入接口电连接, 第一射频线的第二端与第一壳体电 连接。
第一壳体用于作为天线臂, 通过第一射频线与第一无线通信模块进行射频信号的交 互。
该第一无线通信模块可以是提供 WCDMA通信服务的无线通信模块, 也可以是提供 WiFi通信服务的无线通信模块, 还可以是提供 TD-SCDMA通信服务的无线通信模块, 当 然, 还可以是提供其它无线通信服务 (如地面数字电视服务) 的无线通信通信模块, 在此

PAD等设备, 其外壳也是分为了两个部分。
而一般而言,为无线通信提供信号传输的天线可以有两种:单极子天线和偶极子天线, 本发明实施例既可以实现单极子天线, 也可以实现偶极子天线, 分别说明如下。
<单极子天线 >
在第一壳体和第二壳体均为导电壳体的情况下, 可以使用任意一个壳体作为天线臂来 形成单极子天线, 以第一壳体作为天线臂说明如下。

第一射频线的第二端需要连接到天线臂, 即第一壳体。 从图 6可以发现, 第一射频线 中包括两个导体: 芯线 11 和屏蔽层 13。 在形成单极子天线的情况下, 在第一射频线的第 二端, 该芯线 11需要与第一壳体电连接, 而屏蔽层 13直接悬空 (也就是不连接任何其它 器件) 即可。
在第一射频线一端连接第一无线通信模块, 一端与第一壳体电连接之后, 无线通信模 块即可通过该第一射频线建立与该第一壳体之间的电连接, 以进行射频信号的传输。 第一 壳体即可作为单极子天线进行信号的收发处理。

在第一壳体形成单极子天线时, 在转动连接机构上设置第一导电区域。 第一导电区域 与第一壳体电连接, 且与第二壳体电绝缘。 在第一射频线的第二端, 第一射频线中的芯线 与第一导电区域电连接。 屏蔽层直接悬空即可。
<偶极子天线>
在第一壳体和第二壳体配合形成偶极子天线时, 在转动连接机构上设置相互绝缘的第 一导 1¾区域和第二导电区域。 第一导电区域与第一壳体电连接。 第二导电区域与第二壳体
电连接。 在第一射频线的第二端, 第一射频线中的芯线与第一导电区域电连接。 第一射频 线中的屏蔽层与第二导电区域电连接。
在第一射频线中的芯线、 屏蔽层与第一壳体和第二壳体通过转动连接机构上的导电区 域连接时, 也可以通过调整导电区域在转动连接结构上的位置来实现性能的最优化。
-.1::述的方式中, 只需要将与第一壳体连接的转轴设计成金属转轴, 并与转轴容纳装置 上的第一导电区域形成电连接即可。转轴容纳装置上的第二导电区域与第一导电区域绝缘, 但与第二壳体电连接。 因此实现简单, 同时只需要对转动连接结构进行改变, 并不需要改 变电子设备的整体结构。
在本发明的具体实施例中, 利用导电壳体作为天线臂时, 为了改善阻抗匹配, 降低功 率损耗, 在本发明的具体实施例中, 该电子设备还包括匹配电路。 该匹配电路设置于第一 射频线的第二端和第一壳体之间。 匹配电路的一端与第一壳体电连接, 在第一射频线的第 二端, 第一射频线中的芯线与匹配电路的另一端电连接。
当然, 在单极子天线的情况下, 在第一射频线的第二端, 第一射频线中的屏蔽层直接 悬空。 在偶极子天线的情况下, 在第一射频线的第二端, 第一射频线中的屏蔽层电连接到 第二壳体。
而当通过上述转动连接机构来实现时, 匹配电路的另一端通过第一导电区域与第一壳 体电连接。
当然, 考虑作为天线臂的壳体经常被用户触摸, 此时, 天线的阻抗会发生变化。 在这 种情况下, 为了实现阻抗的自适应调整, 匹配电路为一可调电路结构。
图 8为本发明实施例中一种匹配电路的结构示意图。 如图 8所示, 匹配电路具体包括 第一电阻 Rl、 可调电容 C1和调节电路。
第一电阻 R1 的一端接地, 另一端与第一连接点 (图中左边的黑点) 电连接。 当然, 该电阻也可以使用电容来替换。
可调电容 C1的一端接地, 另一端与第二连接点 (图中右边的黑点) 电连接。
调节电路的一端与第一连接点电连接, 另一端与第二连接点电连接。
第一壳体与第一连接点电连接, 在第一射频线的第二端, 第一射频线中的芯线与第二 连接点电连接。
该调节电路中 E少包括一可调器件, 如可调电感或者可调电容。 下面说明一种具体的 实现方式如下。
如图 8所示, 该调节电路具体包括一并联电路和第二电容 C2 , 并联电路和第二电容 C2以串联方式连接。 该并联电路包括相互并联的可调电感、 第二电阻和第三电容。
上述如图 8所小的电路中, 在天线的阻抗会发生变化吋, 能够通过调解可调电容 C 1 和 /或可调电感中来实现阻抗自适应匹配, 改善了阻抗匹配, 降低了功率损耗。
为了进一歩实现静电防护功能, 本发明实施例的电子设备还包括用于实现静电防护的 静电防护电路。 静电防护电路的一端与第一壳体电连接, 另一端接地。
图 9为本发明实施例中一种 ESD防护电路的结构示意图。 如图 9所示, 为一种静电 防护电路的具体结构示意图, 其中包括: 第四电容 C4、 第五电容 C5和 ESD保护器件 Dl。
第四电容 C4的一端与第一壳体电连接, 而另一端通过 D1接地。 第五电容 C5—端接 地, 另一端连接到连接 C4和 D1的连接线上。 ESD 保护电路与匹配网络结合, C1为匹配 网络电容, C5为 ESD保护器件 D1的寄生,电容。
当然, 上述的静电防护电路和匹配电路可以单独使用, 但也可以结合起来使用。 在本发明的具体实施例中, 以上都是以一个无线通信模块进行的说明, 但应当理解的 是, 本发明实施例也可以利用相同的导电壳体为不同的无线通信模块提供收发服务, 说明 如下。
本发明实施例的电子设备包括第一壳体, 第一壳体为导电壳体, 其中- 所述电子设备还包括:
第一无线通信模块, 设置有第一输入接口;
第二无线通信模块, 设置有第二输入接口;
第一射频线, 具有第一端和第二端, 其中, 所述第一射频线的第一端与所述第一输入 接口电连接, 所述第一射频线的第二端与所述第一壳体电连接;
第二射频线, 具有第一端和第二端, 其中, 所述第二射频线的第一端与所述第二输入 接口电连接, 所述第二射频线的第二端与所述第一壳体电连接;
其中, 所述第一壳体用于作为天线臂, 通过所述第一射频线与所述第一无线通信模块 进行射频信号的交互。
当然, 考虑到不同的无线通信模块的工作频段不同, 在本发明的具体实施例中, 该电 子设备中还包括:
第一滤波电路, 经第一滤波电路过滤后的信号处于第一无线通信模块的工作频段; 第二滤波电路, 经第二滤波电路过滤后的信号处于第二无线通信模块的工作频段;
匹配电路;
所述第一滤波电路的第一端和第二滤波电路的第一端分别通过所述匹配电路与所述 第一壳体电连接;
所述第一射频线的第二端, 所述第一射频线中的芯线与所述第一滤波电路的第二端电 连接;
在所述第二射频线的第二端, 所述第二射频线中的芯线与所述第二滤波电路的第二端 电连接; 其中, 所述第一壳体用于作为天线臂, 通过所述匹配电路、 第一滤波电路、 第一射频 线与所述第一无线通信模块进行射频信弓的交互, 并通过所述匹配电路、 第二滤波电路、 第二射频线与所述第二无线通信模块进行射频信号的交互。
以第一无线通信模块为 3G全频段无线通信模块,而第二无线通信模块为 WiFi无线通 信模块为例说明如下。
图 10为本发明实施例中的滤波电路的一种实现方式的结构示意图。 如图 10所示, 端 口 2和 3分别连接第一射频线和第二射频线, 而端口 1连接匹配网络。 此时匹配网络输出 的信号会分别输出到上方的电路和下方的电路, 经过端口 2和 3分别输出到第一射频线和 第二射频线, 进而传输到为 3G全频段无线通信模块和 WiFi无线通信模块。 由于端口 2和 3输出的信号己经进行了频率的过滤, 所以相对于不经过滤波电路的方式, 其效果更好。
通过对图 9中电阻、 电容和电感的参数的选择, 可以滤除不同频段的信号, 满足无线 通信模块的需求。 当然, 应当理解的是, 上述的具体电路结构可以千变万化, 上述仅仅是 列举一种可能实现的具体电路结构, 并不能说明本发明实施例仅能使用图 9所示的特定电 路结构来实现。
当然, 在上述的无线通信模块为 3个或 3个以上时, 只不过并联的滤波电路相应增加 而言, 并没有其他的差别, 在此不再详细描述。
上述的各种电路都可以单独设置或者集成到主板上, 但其设置方式并不会对本发明实 施例造成影响, 在此不再详细描述。
虽然上面描述的是高频电流从第一壳体上通过的情况为例来描述,但是如图 7~10所示 的实施例中, 高频电流也可以不从第一壳体上通过, 即仅仅用第一壳体来充当天线的天线 臂, 用于接收或者发送辐射射频信号。
图 11为本发明实施例中实现第一壳体和第一导电体短路的结构示意图。在本发明实施
例的屯子设备中, 禾拥电子设备中的导电壳体作为无线发射的天线臂, 并通过射频线连接 无线通信模块和导电壳体, 在无线通信 块和导电壳体间进行射频信号的交互, 在实现天 线功能的同时, 降低产品成本, 提高材料质感与机构强度。
如图 11 所示的电子设备包括一第一壳体, 第一壳体为导电壳体。 所述电子设备还包 括: 第一无线通信模块; 第一射频线和第一导体。
第一无线通信模块设 S有第一输入接口。 第一射频线具有第一端和第二端, 其中, 所 述第一射频线的第一端与所述第一输入接口电连接, 所述第一射频线的第二端与所述第一 壳体电连接。 第一导电体与地连接, 且与所述第一壳体间隔一定距离。
在第一射频线的第二端, 第一射频线中的芯线与所述第一壳体电连接, 所述第一射频 线中的屏蔽层与所述第一导电体电连接。 第一无线通信模块通过所述第一壳体和所述第一 导电体实现射频信号的收发。
上述的射频线的实施例如图 6所示, 射频线包括如下几个部分: 中央的芯线 11 ; 包覆 所述芯线 11的第一绝缘层 12; 包覆所述绝缘层 12的屏蔽层 13, 为导电材质形成; 包覆所 述屏蔽层 13的第二绝缘层 14。
该第一无线通信模块可以是提供 WCDMA通信服务的无线通信模块, 也可以是提供
Wifi通信服务的无线通信模块, 还可以是提供 TD-SCDMA通信服务的无线通信模块, 当 然, 还可以是提供其它无线通信服务 (如地面数字电视服务) 的无线通信通信模块, 在此 不一一列举, 不管无线通信模块的通信制式如何, 其差别仅在于响应频段的差别, 在天线 的工作方式上没有差别。
在本发明的具体实施例中, 该第一导电体安装于第一壳体时, 其通过一个绝缘件安装 到第一壳体上, 第一导电体与第一壳体的相对位置关系并不一定, 可以是二者之间平行, 也可以是不平行。
该导电体与地连接可以是与电子设备的地连接 (如主板地等), 也可以是通过射频线 屏蔽层连接到无线通信模块的地。
当然, 在本发明的具体实施例中, 当第一导电体设置于电子设备的具有显示屏的壳体 内时, 考虑到第一导电体与第一壳体相对的部分会额外产生寄生电容, 为了降低寄生电容 的影响, 在本发明的具体实施例中, 所述第一导电体采用如图 12所示的片状金属体结构, 第一导电体垂直于该金属壳体, 所述片状金属体的面积较小的侧边与所述第一壳体相对, 降低了第 - 导电体与金属壳体之间的相对面积, 从而减小寄生电容。
当采用上述方式时 ·, 第一导电体垂直于金属壳体 (即第一壳体), ώ于天线具有一定的 尺寸要求, 如果第一导电体的高度小于安装有显示屏的壳体高度时, 则这种结构没有什么 问题, 但当第一导电体的高度高于安装有显示屏的壳体高度时, 此时需要在壳体安装有显 示屏的一面设置一凸起结构来容纳第一导电体高出壳体的部分。 从而不改变电子设备的外 观面的完成性, 即闭合状态下的外表面的形状平整。
而考虑到第一壳体与第二壳体的转动连接, 该第一导电体设置于壳体上位于两个转动 连接结构之间的部分。
而考虑到第一壳体与第二壳体的转动连接, 还需要保证该凸起结构在转动过程中不会 与安装主板的下壳体干涉, 此时, 应该在安装主板的壳体上设置一凹槽结构 (如一个弧形 槽), 使得凸起结构在转动过程中不会与安装 ±板的下壳体干涉, 一种具体的形状如图 12 所示。
一般而言, 电子设备的外壳都包括至少两个壳体, 即第一壳体和第二壳体, 如笔记本 电脑包括用于装配 LCD屏的第一壳体和用于装配主板的第二壳体, 而如翻盖、滑盖的手机 也包括用于装配 LCD屏的第一壳体和用于装配主板的第二壳体,而即使是直板手机和 PAD 等设备, 其外壳也是分为了两个部分。
在本发明的具体实施例中, 上述的第一壳体作为天线的一个辐射枝, 而第一导电体与 电子设备的地连接, 作为天线地, 其中射频线的芯线与所述第一壳体电连接, 所述第一射 频线中的屏蔽层与所述第一导电体电连接, 通过这种连接方式, 形成了利用金属壳体实现 了天线功能的同时, 降低了产品成本, 同时, ώ于不再需要在金属外壳上割开一块电磁净 空区域, 也不需要利用塑胶与金属一体成型方式来制作外壳, 因此提高了材料质感与机构 强度。
上述的芯线是用于传输射频信号, 因此与作为辐射面的第一壳体电连接, 而屏蔽层则 与作为天线地的第一导电体电连接。
至于芯线与第一壳体的馈点位置的设置以及屏蔽层与第一导电体的连接点的设置与天 线的响应频率、 第一壳体的面积以及第一导电体与壳体间的距离、 以及第一导电体与壳体 之间的相对面积等因素相关, 简要说明 下。
众所周知的频率谐振公示如下:
戶 1 / ( 2π(Ζ,01 2)
天线的工作原理天线本身就是一个振荡器, 在第一壳体的面积确定的情况下, 调整馈
点的位肾、 第 ·· -壳体与第一导电体之间的距离以及第一导电体与壳体之间的相对面积等就 nj'以改变其中的电感 L和 /或电容 C, 使得天线能够工作在合适的频段。
上述的天线结构中, 为了使得天线能够工作在合适的频段, 第一导电体的长度要求较 大, 但考虑到电子设备的体积小型化的趋势, 为了降低第一导电体的长度需求, 在本发明 的具体实施例中, 在本发明的具体实施例中, 如图 12所示, 还包括:
第二导电体 25, 一端¾连接所述第一导电体 26, 另一端电连接所述第一壳体 21。 通过上述第二导电体 25的设置,在第一导电体 26和第一壳体 21之间形成了短路连接, 其中第二导电体 25通过焊接点 24与第一壳体 21之间形成了电连接, 而射频线 23的屏蔽 层与第一导电体 26连接, 而射频线 23的芯线则在馈点 23处与第一壳体 21连接。
由于第二导电体 25, 在第一导电体 26和第一壳体 21之间形成了短路连接, 使得第一 壳体 21、 第一导电体 26形成了 PIFA (皮法)天线, 降低了第一导电体 26的长度要求, 使 得天线更加小型化, 能够适用于更多的电子设备。
本发明具体实施例中, 在金属外壳的上方, 搭建一个电磁回路, 利用 PIFA天线原理, 把金属壳体作为 PIFA的辐射枝, 悬空构建的回路作为天线的地。回路与金属壳体部可有一 个或是多个短路点, 来调整天线频宽。
在本发明的具体实施例中, 利用导电壳体作为天线臂时, 为了改善阻抗匹配, 降低功 率损耗, 在本发明的具体实施例中, 该电子设备还包括如图 8所示的匹配电路, 设置于第 一射频线的第二端和第一壳体之间。
这样, 即使作为天线臂的壳体经常被用户触摸而导致天线的阻抗发生变化时, 由于匹 配电路的某些参数, 例如电感或者电容是可调的, 所以能够自动适应阻抗的变化。
以上所述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, 在不脱离本发明原理的前提下, 还可以作出若干改进和润饰, 这些改进和润饰也应视 为本发明的保护范围。
