技术领域 technical field
本发明关于一种平板天线结构及具有平板天线结构的电子装置，特别是一种可供微调天线的特性的平板天线结构及具有平板天线结构的电子装置。The present invention relates to a planar antenna structure and an electronic device with the planar antenna structure, in particular to a planar antenna structure capable of fine-tuning the characteristics of the antenna and an electronic device with the planar antenna structure.
背景技术 Background technique
在无线通信与生活紧密结合的现代，无论身在何处都会接触到与无线传输相关的产品及应用，而天线是在无线传输系统中用来发射与接受电磁波能量的重要元件。天线分成很多种，其中平板天线具有便宜、能与电路轻易的结合并有着结构简单的特色。In the modern era where wireless communication is closely integrated with life, no matter where you are, you will come into contact with products and applications related to wireless transmission, and antennas are important components used to transmit and receive electromagnetic wave energy in wireless transmission systems. There are many types of antennas, among which the flat panel antenna is cheap, can be easily combined with the circuit, and has the characteristics of simple structure.
目前市面上的卫星平板天线是由特氟龙(Teflon)复合材料制作出圆形的平板，再采用印刷电路板制程在平板两侧覆上互相平行的铜层。其中特氟龙为一种树脂，化学名称为聚四氟乙烯(polytetrafluoroethylene)。由于特氟龙是由碳原子和氟原子制成，不含氢，所以不会和氧发生反应，具有耐热、耐低温、耐蚀性、优异的非粘着性及自润性、低摩擦系数及低介电常数等特性。其中因为其低介电常数的特性，使特氟龙长期以来是平板天线里重要的基材之一。Currently, the satellite flat panel antennas on the market are circular flat panels made of Teflon (Teflon) composite material, and then coated with copper layers parallel to each other on both sides of the flat panel by using a printed circuit board process. Among them, Teflon is a kind of resin, and its chemical name is polytetrafluoroethylene (polytetrafluoroethylene). Since Teflon is made of carbon atoms and fluorine atoms and does not contain hydrogen, it will not react with oxygen. It has heat resistance, low temperature resistance, corrosion resistance, excellent non-adhesion and self-lubricating properties, and low coefficient of friction. And low dielectric constant and other characteristics. Among them, because of its low dielectric constant, Teflon has long been one of the important substrates in flat panel antennas.
但因特氟龙复合材价格昂贵又不易回收，平板冲切制程也会产生许多不可回收的废料，因此，有必要提供一种新的天线结构，以改善先前技术所存在的问题。However, the Teflon composite material is expensive and difficult to recycle, and the flat die-cutting process will also produce a lot of non-recyclable waste. Therefore, it is necessary to provide a new antenna structure to improve the problems existing in the previous technology.
发明内容 Contents of the invention
本发明的主要目的在与取代特氟龙为基材的平板天线结构。The main purpose of the present invention is to replace Teflon as the base plate antenna structure.
本发明的另一主要目的在于提供微调天线的特性的平板天线结构。Another main object of the present invention is to provide a planar antenna structure for fine-tuning the characteristics of the antenna.
为达成上述的目的，本发明提供一种平板天线结构，及具有该平板天线结构的电子装置。本发明的平板天线结构包括第一金属片、中间层、金属环及第二金属片。其中中间层包括第一孔洞，中间层设置在第一金属片之上并与第一金属片连结；金属环穿过第一孔洞与第一金属片连结；且第二金属片包括第二孔洞，第二金属片与金属环连结，且第二金属片与第一金属片连结，以使中间层与金属环被第一金属片及第二金属片包覆。借此，第二金属片可借由金属环与第一金属片电性导通，第一金属片及第二金属片间形成谐振腔，且借由改变第一孔洞及金属环的直径可调整天线的特性。在本发明的一实施例中，中间层为塑料片以取代特氟龙。To achieve the above objectives, the present invention provides a planar antenna structure and an electronic device having the planar antenna structure. The planar antenna structure of the present invention includes a first metal sheet, an intermediate layer, a metal ring and a second metal sheet. Wherein the intermediate layer includes a first hole, the intermediate layer is arranged on the first metal sheet and connected with the first metal sheet; the metal ring passes through the first hole and is connected with the first metal sheet; and the second metal sheet includes a second hole, The second metal sheet is connected to the metal ring, and the second metal sheet is connected to the first metal sheet, so that the middle layer and the metal ring are covered by the first metal sheet and the second metal sheet. In this way, the second metal sheet can be electrically connected to the first metal sheet through the metal ring, and a resonant cavity is formed between the first metal sheet and the second metal sheet, and can be adjusted by changing the diameter of the first hole and the metal ring characteristics of the antenna. In an embodiment of the present invention, the middle layer is a plastic sheet instead of Teflon.

具体实施方式 Detailed ways
为能更好了解本发明的技术内容，特举优选具体实施例说明如下。In order to better understand the technical content of the present invention, preferred specific examples are given as follows.
以下请一并参考图1至图3关于本发明的平板天线结构的实施例。图1为本发明的平板天线结构的分解透视图；图2为本发明的平板天线结构的立体示意图；且图3为本发明的平板天线结构的组合示意图。Please refer to FIG. 1 to FIG. 3 for the embodiment of the planar antenna structure of the present invention. 1 is an exploded perspective view of the planar antenna structure of the present invention; FIG. 2 is a perspective view of the planar antenna structure of the present invention; and FIG. 3 is a combined schematic view of the planar antenna structure of the present invention.
如图1至图3所示，平板天线结构1包括第一金属片20、中间层30、金属环40及第二金属片50。其中中间层30包括第一孔洞31，中间层30设置在第一金属片20之上并与第一金属片20连结；金属环40穿过第一孔洞31与第一金属片20连结。第二金属片50包括第二孔洞51，第二金属片50与金属环40连结，并且第二金属片50与第一金属片20铆压连结，以使中间层30与金属环40被第一金属片20及第二金属片50包覆。借此，第二金属片50可借由铆压而与第一金属片20电性导通，以及可借由金属环40与第一金属片20电性导通。As shown in FIGS. 1 to 3 , the
如图3所示，第一金属片20及第二金属片50所包覆的中间层30形成谐振腔11，且借由改变第一孔洞31及金属环40的直径可调整天线的特性。因为金属环40直径的改变，改变了谐振腔11的范围，因此天线的特性也随之改变。As shown in FIG. 3 , the
在本发明的一实施例中，中间层30为塑料片，塑料片具有低介电常数的特性，因此可取代特氟龙做为平板天线结构1的一基材。如图3所示，为加强平板天线结构1的紧密结合，第一金属片20与第二金属片50以铆压连结的方式连结，但本发明并不以此为限。在本发明的一实施例中，中间层30为高密度聚乙烯(high density polyethylene，HDPE)，但本发明不以此为限。In an embodiment of the present invention, the
如上所述，金属环40在本发明中的作用除了电性导通第一金属片20及第二金属片50外，借由调整金属环40的直径，即可调整平板天线结构1的天线的特性。此外金属环40因具有强度，因此在第一金属片20与第二金属片50铆压接合时，可避免第一金属片20与第二金属片50因铆压时的重量而变形。举例而言，如图4所示，若平板天线结构1缺乏金属环40，则平板天线结构1在铆压接合时，第二金属片50可能因铆压时的重量而部分变形。As mentioned above, the role of the
如图3所示，在本发明的一实施例中，第一金属片20具有突出部201，该突出部201与金属环40具有相对应的螺旋结构(图未示)，以使第一金属片20与金属环40螺旋接合，但本发明并不以此为限。中间层30与第一金属片20以粘合方式连结，中间层30与第二金属片50亦以粘合方式连结。举例来说，在中间层30与第一金属片20间及中间层30与第二金属片50，分别加一双面粘胶片，即可达到粘合方式连结，但本发明不以为限。As shown in FIG. 3, in an embodiment of the present invention, the
在本发明的一实施例中，第一金属片20、第二金属片50及金属环40为铜或铜合金，但本发明不以此为限。举例来说，第一金属片20、第二金属片50及金属环40亦可为银或银合金；只要是导电性佳的金属，均可为本发明的第一金属片20、第二金属片50及金属环40所使用的材料。In an embodiment of the present invention, the
以下请一并参考图5A及图5B关于本发明的具有平板天线结构的电子装置的实施例的示意图。In the following, please refer to FIG. 5A and FIG. 5B together for a schematic view of an embodiment of an electronic device with a planar antenna structure according to the present invention.
如图5A所示，本发明提供一种具有平板天线结构的电子装置7A，其包括电子装置本体70A及平板天线结构1。在本发明的一实施例中，电子装置本体70A为全球定位系统，但本发明不以此为限。As shown in FIG. 5A , the present invention provides an
如图5B所示，本发明提供一种具有平板天线结构的电子装置7B，其包括电子装置本体70B及平板天线结构1。在本发明的一实施例中，电子装置本体70B为卫星收音机，但本发明不以此为限。As shown in FIG. 5B , the present invention provides an
综上所陈，本发明无论就目的、手段及功效，均显示其迥异于传统技术的特征，但应注意的是，上述诸多实施例仅为了便于说明而举例，本发明的范围自应以权利要求书所述为准，而非仅限于上述实施例。In summary, no matter the purpose, means and effect of the present invention, it all shows its characteristics that are very different from the traditional technology. The claims shall prevail, not limited to the above examples.
