当天线的数量变多时,天线于电子产品内的布局亦会变得困难。研发人员需费心考量该多个天线放置在电子产品内的何处才能有较好的效率、且如何不占据其他电子元件/模块的设置空间等问题。更甚者,当电子产品越来越薄型化时,其内部可供利用的空间更有限,天线的布局将更显困难。
因此,如何在电子产品内的有限及复杂的可利用空间中,设计一个符合所需频率的天线,乃为此业界待解决的问题。

【具体实施方式】
请参阅图1至图3所示,其为依据本发明第一较佳实施例的无线通信装置的各示意图。该无线通信装置1可为具有无线通信功能的电子产品或该电子产品的一部分,例如智慧型手机或平板电脑等,可通过适当的通信协定(例如3G、4G、5G、WiFi、BT、LTE)来传输资料。
该无线通信装置1可包含一电路板10、多个电子元件20、多个条导线30、至少一个输入元件40、一天线元件50、一背盖70、一玻璃盖板90(如图8所示)以及至少一个处理器80;较佳地,无线通信装置1更可包含一或多个信号过滤器60(或称滤波器)。其中背盖70及玻璃盖板(cover glass)90是形成无线通信装置1的整体外观件,背盖70可由非导体制成,可由导体制成,或由导体及非导体混合制成。
输入元件40是用以感测使用者的输入,而输入元件40可包含一电容式触控元件、一电阻式触控元件、一电感式触控元件及一光学式触控元件的其中之一,再结合触控显示面板模块(图未示)上的玻璃盖板90来感测使用者的输入;本实施例中,输入元件40是以电容式触控元件来实现。该多个元件的技术内容将依序说明如下。
如图1所示,电路板10可做为电子产品内的主要的电路板,其可供大部分电子元件20设置其上,而一些机械构件(例如支撑触控显示面板模块的框架,电连接器等,图未示)亦可设置于电路板10上。外型上,电路板10大致呈现一矩型,而其周缘10A可有突出部分或内凹部分;实际应用上的电路板10的形状并不局限于此,亦可为其他形状。
结构上,电路板10可包含一电路图案层(图未示),使得电子元件20之间能直接地或间接地相互电性连接,以互相传递电信号。电路板10更包含一或一个以上的接地层11,其可为于电路板10的外层或内层(即不外露);接地层11可作为一金属层,例如铜箔层。
电子元件20可设置于电路板10上,例如通过焊料或电连接器(图未示)等方式来设置于电路板10上,电子元件20可与电路板10的电路图案层及/或接地层11相电性连接。电子元件20至少包含一射频信号模块21以及一触控信号模块22,且两模块分别与处理器80电性连接。射频信号模块21(或称射频控制模块)是用以收发一射频信号(或称射频微波信号),并与其他无线通信相关联的电子元件电性连接,以进一步借由处理器80来处理该射频信号,例如射频信号与数字信号的转换、功率放大等。射频信号模块21可包含一或多个芯片211,亦可包含一阻抗匹配电路212,亦可与其他电子元件相整合于一芯片中。
触控信号模块22(或称触控控制模块)及处理器80可用以处理来自触控显示面板模块及输入元件(即电容式触控元件)40的触控信号,例如从触控信号的电流判断电容式触控元件40的电容量、依据该电容量判断电容式触控元件40是否被触碰等;触控信号模块22亦可驱动电容式触控元件40。如上所述,触控信号模块22还可与其他电子元件电性连接,以将判断结果传输至该电子元件进一步应用。触控信号模块22可包含一或多个芯片,亦可与其他电子元件相整合。
依据实际应用或需求,电子元件20尚可包含存储器、电池、触控显示面板、各种传感器及/或信号处理芯片等(图未示),以提供无线通信装置1的各种功能。
请配合参阅图2、图3及图8,该多个导线30用以传输电信号至电路板10、电子元件20、电容式触控元件40及/或天线元件50,该多个导线30包含一接地导线31、一触控信号导线32及一射频信号导线33,各导线31~33可为印刷于电路板10上的电路图案层及/或相对于电路板10为独立的金属线,其中独立的金属线可设置于柔性印刷电路基板(FPCB)30’之上(如图8所示),而柔性印刷电路基板30’亦可借由导线12与电路板10做电性连接。结构上,柔性印刷电路基板30’是配置于玻璃盖板90的下方。
此外,各导线31~33包含相反的两端(即一端31A~33A与另一端31B~33B),电信号可于该两端之间传输;其中,接地导线31的一端31A电性连接至电路板10的接地层11、另一端31B电性连接至电容式触控元件40,触控信号导线32的一端32A电性连接至触控信号模块22、另一端32B电性连接至电容式触控元件40,而射频信号导线33的一端33A电性连接至射频信号模块21、另一端33B电性连接至天线元件50。
电容式触控元件40可定义一电容值,并且可因应使用者的手指等导电物体接近而改变其电容值,然后触控信号模块22可感测该电容值的变化量而判断电容式触控元件40是否被碰触。如此,使用者可通过碰触电容式触控元件40,来传递特定指令给无线通信装置1。如图1所示,电容式触控元件40可选择地设置于电路板10的周缘A的一侧旁,与电路板10相分隔。电容式触控元件40可为按键(key)、卷动条(scroll bar)、圆盘(wheel)、板(pad)等型态。
请配合参阅图8,其中,按键(key)依其结构设计方式,又可分成实体按键(physical key)及虚拟按键(virtual key),且两种按键皆可具有特定的图案100以供使用者理解个别按键的功效,这两种按键可再与触控显示面板模块(图未示)上的玻璃盖板(cover glass)90作结合而形成一输入感测区域90A,借此来感测与接收使用者的输入,其中,感测区域90A是根据输入元件40所在的位置而定,并不局限于玻璃盖板90上的固定位置。
技术上,当触控显示面板模块内的显示面板模块于关闭状态下(即显示器不亮时),配置于按键上的图案100是看不见时,此即定义为虚拟按键;若不论显示面板模块于关闭或开启状态下,按键上的图案100都是看得见时,此即定义为实体按键(此时图案100可能印刷于玻璃盖板90上)。
本实施例中,电子元件20还包括至少一个输入元件23,其亦可接收使用者的输入以与无线通信装置1进行沟通,该输入元件23可为传统按钮而被被使用者按压,或者由电容式触控元件、一电阻式触控元件、一电感式触控元件及一光学式触控元件的其中之一来实现。再者,亦可将生物辨识模块(未显示)整合于输入元件23中,借以增加无线通信装置1内的资料防护。其中玻璃盖板90具有一开口,而输入元件23是配置于开口内。可理解地,输入感测区域90A可设置于输入元件23的周遭区域,以利使用者的操作。
复参阅图2及图3,结构上,电容式触控元件40可包含一感测层41、一介电层42以及一接地层43,介电层42设置于感测层41与接地层43之间,或可说,感测层41、介电层42及接地层43依序地堆叠。于其他实施方式中,介电层42亦可环绕感测层41,而接地层43再环绕介电层42,故介电层42仍是设置于感测层41与接地层43之间。
感测层41可由一导体材料(例如铜箔等金属层、或氧化铟锡等氧化物)所制成,介电层42可由介电材料(例如塑胶、树脂、玻璃等)制成、或可包含空心部分,以利用空气作为介电材料。接地层43可由导体来制成,还可具有一网状结构;其他实施例中,接地层43可具有一非网状结构。接地层43可称为第二接地层,而前述电路板10的接地层11可称为第一接地层,以示区别。
感测层41可电性连接至触控信号导线32的另一端32B,而接地层43可电性连接至接地导线31的另一端31B。如此,当感测层41与接地层43之间的电容值产生变化时,相应的触控信号可通过触控信号导线32传递至触控信号模块22。
天线元件50用以接收及/或发射具有特定频率的射频信号,其结构上包含一馈入点51以及一辐射本体52,馈入点51设置于电容式触控元件40的接地层43上、且电性连接至射频信号导线33的另一端33B;换言之,馈入点51可定义为射频信号导线33的另一端33B设置于接地层43的一位置,射频信号即由馈入点51来馈入至接地层43。馈入点51与接地导线31的另一端31B位于接地层43的不同处,彼此相距。
辐射本体52包含该接地层43的至少一部分或全部,以利用接地层43来接收或发射电磁波。也就是,由馈入点51进入至接地层43的射频信号会传递于接地层43中,并且产生电磁波;另一方面,环境中的电磁波接触到接地层43时,可在接地层43中产生射频信号,然后通过馈入点51、射频信号导线33至射频信号模块21。因此,于接地层43中,射频信号所传递经过的一部分可定义为辐射本体52。
射频信号除了于接地层43中辐射,在射频信号导线33及接地导线31中亦会辐射,因此射频信号导线33及接地导线31亦可视为辐射本体52所包含的另一部分。所以,天线元件50的总辐射路径可定义为:从射频信号导线33的一端33A开始、通过接地层43的一部分至接地导线31的一端31A结束。调整此辐射路径的长度(例如改变馈入点51的位置、改变射频信号导线33或接地导线31的长度等)可改变辐射本体52的共振频率,以得到所需者。此外,由于接地导线31亦可作为辐射本体52的一部分,辐射本体52整体可视为是一个环形天线(loop antenna),其辐射路径符合二分之一的波长。
由上述说明可知,本实施例中无线通信装置1是将天线元件50与输入元件(即电容式触控元件)40相整合,直接利用电容式触控元件40的接地层43来接收或发射电磁波。如此,天线元件50与电容式触控元件40可容置于相同的空间,不需额外的空间来容置另一者,有利于无线通信装置1的尺寸缩减或是空间利用。
本实施例中无线通信装置1尚可包含多个信号过滤器60(如图1所示),以减少或避免触控信号干扰射频信号模块21、或是射频信号干扰触控信号模块22。信号过滤器60(或称滤波器)可包括一触控信号过滤器61及/或一射频信号过滤器62。
触控信号过滤器61电性连接于射频信号导线33上,可与射频信号导线33串联;触控信号过滤器61对于直流或低频的触控信号而言,具有较大的阻抗,以阻挡触控信号通过。如此,电容式触控元件40所产生的触控信号无法通过触控信号过滤器61,进而无法通过射频信号导线33而进入至射频信号模块21;射频信号模块21不会被触控信号干扰。
触控信号过滤器61对于高频的射频信号而言,具有较小阻抗,故不会阻挡射频信号通过,因此,射频信号不会因为触控信号过滤器61而无法通过射频信号导线33。触控信号过滤器61可包括一电容器(例如串联的电容器)等电子元件,可使触控信号为开路者,但使射频信号为短路者。
射频信号过滤器62电性连接于触控信号导线32上,可与触控信号导线32串联;射频信号过滤器62对于高频的射频信号而言,具有较大的阻抗,以阻挡射频信号通过。如此,天线元件50所产生的射频信号无法通过射频信号过滤器62,进而无法通过触控信号导线32而进入至触控信号模块22;触控信号模块22不会被射频信号干扰。
射频信号过滤器62对于直流或低频的触控信号而言,具有较小阻抗,故不会阻挡触控信号通过,如此,触控信号不会因为射频信号过滤器62而无法通过触控信号导线32。射频信号过滤器62可包括一电感器(例如串联的电感器)等电子元件,可使射频信号为开路者,但使触控信号为短路者。
综上,触控信号过滤器61及射频信号过滤器62分别可增加射频信号模块21及触控信号模块22的可靠度。
在一个实际测试范例下,无线通信装置1应用于一尺寸为144.6mm乘69.7mm乘9.61mm的行动电话中,而接地层43的尺寸为6mm乘17mm乘0.1mm;阻抗匹配电路212为一并联接地电容(电容值为0.8pF);触控信号过滤器61为一1.8pF的电容器,射频信号过滤器62为一10nH的电感器。所量测到的频率(MHz)与电压驻波比(VSWR)的关系如图7所示,而频率(MHz)与效率(%)的关系如下表所示。
频率 | 1710.2 | 1747.8 | 1784.8 | 1805.2 | 1850.2 | 1880 | 1909.8 | 1930.2 |
效率 | 11.19 | 11.87 | 12.05 | 12.27 | 13.06 | 15.60 | 16.63 | 17.95 |
频率 | 1960 | 1989. | 2010 | 2025 | 2110 | 2140 | 2167. | 2300.8 |
效率 | 17.92 | 17.74 | 17.04 | 16.81 | 15.48 | 15.32 | 16.16 | 17.85 |
频率 | 2350 | 2399. | 2500 | 2540 | 2580 | 2610 | 2650 | 2690 |
效率 | 16.27 | 17.07 | 13.77 | 14.11 | 11.97 | 10.33 | 11.56 | 9.95 |
由上表可知,从中频(1700MHz)至高频(2700MHz)之间的各频段的效率大致上大于10%,表示无线通信装置1在该多个频率中皆有不错效率,适合应用载波聚合(carrieraggregation,CA)技术。因此,无线通信装置1可操作于LTE(Long-Term Evolution)的多个频段(例如B3、B2、B1、B4、B25、B30、B38、B39、B40、B41、B7及WIFI 2.4G)中。
以上是无线通信装置1的技术内容的说明,接着将说明依据本发明其他实施例的无线通信装置1的技术内容,而各实施例的无线通信装置1的技术内容应可互相参考,故相同的部分将省略或简化。
请参阅图4所示,其为依据本发明第二较佳实施例的无线通信装置2的示意图。无线通信装置2与前述无线通信装置1相似,但无线通信装置2的天线元件50的馈入点51可设置于接地层43上离接地导线31的另一端31B较远处,以增加辐射路径。由此可知,调整馈入点51(或另一端31B)在接地层43上的位置可改变辐射路径。
此外,无线通信装置2还可包含另一射频信号过滤器63,该射频信号过滤器63电性连接于接地导线31上,以阻挡射频信号通过接地导线31;射频信号过滤器63可包括一电感器(例如串联的电感器)等电子元件,可使射频信号为开路者。如此,从馈入点51进入至接地层43(辐射本体52)的射频信号无法通过接地导线31而朝向电路板10的接地层11前进。
这样的型态下,接地导线31难以做辐射本体52的一部分,故辐射本体52整体上可视为是一个单极天线(monopole antenna),其辐射路径符合四分之一的波长。
请参阅图5所示,其为依据本发明第三较佳实施例的无线通信装置3的示意图。无线通信装置3与上述无线通信装置1及2的主要不同处在于,无线通信装置3是利用电容式触控元件40’的感测层41作为辐射本体52。
具体而言,在无线通信装置3中,除了触控信号导线32的另一端32B外,射频信号导线33的另一端33B亦是电性连接至感测层41,使得天线元件50的馈入点51设置于感测层41上;辐射本体52则是包含感测层41的至少一部分。如此,射频信号模块21可将射频信号通过馈入点51而馈入至感测层41,以感测层41产生电磁波;或者,环境中的电磁波可被感测层41接收而产生射频信号,射频信号再通过馈入点51及射频信号导线33而传输至射频信号模块21。类似地,射频信号除了于感测层41中辐射,在射频信号导线33中也会辐射,因此射频信号导线33亦可视为辐射本体52所包含的另一部分。所以,天线元件50的总辐射路径可定义为:从射频信号导线33的一端33A开始、通过感测层41的一部分结束。
由于感测层41(辐射本体52)未有电性连接至电路板10的接地层11(如图1所示),故感测层41中的射频信号不会朝向电路板10的接地层11传递。因此,辐射本体52整体上可视为是一个单极天线,其辐射路径符合四分的一的波长。无线通信装置3亦可包含一触控信号过滤器61以及一射频信号过滤器62,以减少或避免触控信号干扰射频信号模块21、或是射频信号干扰触控信号模块22。
另说明的是,天线元件50是利用电容式触控元件40’的感测层41作为辐射本体52,故电容式触控元件40’可不包括接地层,亦不影响天线元件50的构成。换言之,电容式触控元件40’纵使没有接地层,天线元件50亦可整合至此种电容式触控元件40’中。
请参阅图6所示,其为依据本发明第四较佳实施例的无线通信装置4的示意图。无线通信装置4与前述无线通信装置3相似,都是利用电容式触控元件40’的感测层41来作为辐射本体52,不同的处在于:无线通信装置4的射频信号导线33与触控信号导线32具有一共同区段3233,在该共同区段3233中,两者实质同一条导线,而在共同区段3233外,两者为两条导线。射频信号导线33的另一端33B与触控信号导线32的另一端32B设置于共同区段3233上,故两者借由并联的方式电性连接至感测层41。换言之,射频信号导线33与触控信号导线32电性连接至感测层上的位置是相同。
借由共同区段3233的设置,无线通信装置4的线路布局可以简化。若无线通信装置4包含触控信号过滤器61及射频信号过滤器62时,触控信号过滤器61及射频信号过滤器62将会位于共同区段3233之外,以避免触控信号或射频信号无法通过共同区段3233。
另一个与无线通信装置3的不同处在于:无线通信装置4更包括一接地导线31及另一触控信号过滤器64。接地导线31的一端31A电性连接至电路板10的接地层11、而另一端31B电性连接至电容式触控元件40’的感测层41、另一端31B并与馈入点51相距;触控信号过滤器64则电性连接于接地导线31上,其可阻挡触控信号、但可让射频信号通过。因此,接地导线31可作为辐射本体52的一部分,使得天线元件50整体上为一环状天线。此外,由于触控信号过滤器64可阻挡触控信号通过接地导线31而传递至接地层11,故触控信号仍可被触控信号模块22接收处理。
综合上述,本发明各实施例所提出的无线通信装置将天线元件与至少一输入元件(例如电容式触控元件、电阻式触控元件、电感式触控元件及光学式触控元件的其中之一)相整合,该多个输入元件所包含的一感测层可作为天线元件的辐射本体,以节省天线元件所占据的空间。此外,天线元件还可操作于多个频率中,以作为一分集天线(diversity),应用载波聚合的技术。再者,通过信号过滤器的设置,触控信号不会影响射频信号模块,而射频信号不会影响触控信号模块,增加运作的可靠度等。
上述的实施例仅用来例举本发明的实施态样,以及阐释本发明的技术特征,并非用来限制本发明的保护范畴。任何熟悉此技术者可轻易完成的改变或均等性的安排均属于本发明所主张的范围,本发明的权利保护范围应以申请专利范围为准。
