基於上述，本發明的行動電子裝置可透過金屬殼體上的槽孔來形成開槽孔天線。此外，當行動電子裝置中的金屬殼體面對絕緣殼體時，導電片可用以調整開槽孔天線的共振頻率。藉此，將可避免行動電子裝置中的金屬元件對開槽孔天線所造成的影響，從而有助於提升行動電子裝置通訊品質。Based on the above, the mobile electronic device of the present invention can form a slotted hole antenna through a slot in the metal housing. In addition, when the metal housing in the mobile electronic device faces the insulating housing, the conductive sheet can be used to adjust the resonant frequency of the slotted antenna. Thereby, the influence of the metal components in the mobile electronic device on the slotted antenna can be avoided, thereby helping to improve the communication quality of the mobile electronic device.
為讓本發明的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the invention will be apparent from the following description.
圖1A與圖1B分別是依照本發明的一實施例的行動電子裝置的外觀示意圖與剖面示意圖。如圖1A與圖1B所示，行動電子裝置100包括金屬殼體110、絕緣殼體120、第一框體130與第二框體140。其中，金屬殼體110與第一框體130可形成第一機體101，且絕緣殼體120與第二框體140可形成第二機體102。此外，第一框體130可環繞設置在第一機體101上的顯示器103，且第二框體140可環繞設置在第二機體102上的鍵盤與/或觸控板(未繪示出)。1A and 1B are respectively a schematic diagram and a cross-sectional view of a mobile electronic device according to an embodiment of the invention. As shown in FIG. 1A and FIG. 1B , the mobile electronic device 100 includes a metal casing 110 , an insulating casing 120 , a first casing 130 and a second casing 140 . The metal housing 110 and the first frame 130 can form the first body 101 , and the insulating housing 120 and the second frame 140 can form the second body 102 . In addition, the first frame 130 can surround the display 103 disposed on the first body 101, and the second frame 140 can surround a keyboard and/or a touchpad (not shown) disposed on the second body 102.
在一實施例中，行動電子裝置100可例如是一筆記型電腦，且第一機體101與第二機體102可透過樞軸(未繪示出)而相對轉動，進而致使行動電子裝置100可切換至筆記型電腦模式(notebook mode)或是平板電腦模式(tablet mode)。具體而言，樞軸連接在第一機體101與第二機體102之間，進而致使第一機體101與第二機體102可相對地展開或是閉合。此外，當第一機體101相對於第二機體102轉動360度時，行動電子裝置100將可切換至平板電腦模式，且此時第一機體101與第二機體102的相對位置將如圖1A與圖1B所示。In one embodiment, the mobile electronic device 100 can be, for example, a notebook computer, and the first body 101 and the second body 102 can be relatively rotated through a pivot (not shown), thereby causing the mobile electronic device 100 to switch. To notebook mode (notebook mode) or tablet mode (tablet mode). Specifically, the pivotal connection between the first body 101 and the second body 102 causes the first body 101 and the second body 102 to be relatively unfolded or closed. In addition, when the first body 101 is rotated 360 degrees relative to the second body 102, the mobile electronic device 100 can be switched to the tablet mode, and the relative positions of the first body 101 and the second body 102 at this time will be as shown in FIG. 1A. Figure 1B shows.
更進一步來看，金屬殼體110具有一槽孔150，且行動電子裝置100更包括導電片160、饋入元件170、基板180與絕緣結構190。其中，導電片160設置在絕緣殼體120，例如：導電片160可例如是貼附在絕緣殼體120的內壁。饋入元件170、基板180與絕緣結構190設置在第一機體101內。此外，饋入元件170設置在基板180的一表面上，且饋入元件170位在槽孔150的下方。絕緣結構190延伸至槽孔150內，以藉此美化金屬殼體110，並可防止灰塵等異物掉入至第一機體101內。Furthermore, the metal housing 110 has a slot 150, and the mobile electronic device 100 further includes a conductive sheet 160, a feeding element 170, a substrate 180 and an insulating structure 190. The conductive sheet 160 is disposed on the insulating case 120. For example, the conductive sheet 160 may be attached to the inner wall of the insulating case 120, for example. The feed element 170, the substrate 180, and the insulating structure 190 are disposed within the first body 101. Further, the feed element 170 is disposed on a surface of the substrate 180, and the feed element 170 is positioned below the slot 150. The insulating structure 190 extends into the slot 150 to thereby beautify the metal housing 110 and prevent foreign matter such as dust from falling into the first body 101.
值得一提的是，金屬殼體110的槽孔150與饋入元件170可形成一開槽孔天線(open slot antenna)。亦即，金屬殼體110與饋入元件170可形成天線元件。其中，饋入元件170所在的平面實質上平行於金屬殼體110，且饋入元件170橫跨槽孔150。此外，如圖1A與圖1B所示，當行動電子裝置100切換至平板電腦模式時，第一機體101與第二機體102將可相互重疊。此時，金屬殼體110將可面對絕緣殼體120，且導電片160所在的平面實質上平行於金屬殼體110。It is worth mentioning that the slot 150 of the metal housing 110 and the feed element 170 can form an open slot antenna. That is, the metal housing 110 and the feed element 170 can form an antenna element. Wherein, the plane in which the feed element 170 is located is substantially parallel to the metal housing 110, and the feed element 170 spans the slot 150. In addition, as shown in FIG. 1A and FIG. 1B, when the mobile electronic device 100 is switched to the tablet mode, the first body 101 and the second body 102 may overlap each other. At this time, the metal casing 110 will face the insulating casing 120, and the plane of the conductive sheet 160 is substantially parallel to the metal casing 110.
舉例來說，圖2A與圖2B為依照本發明的一實施例的導電片、金屬殼體與饋入元件在平板電腦模式下的配置示意圖與投影示意圖。如圖2A所示，在平板電腦模式下，導電片160、金屬殼體110與饋入元件170三者所在的平面實質上是相互平行的，且槽孔150位在導電片160與饋入元件170之間。此外，在平板電腦模式下，導電片160與饋入元件170在金屬殼體110上的正投影將如圖2B所示。For example, FIG. 2A and FIG. 2B are schematic diagrams and projections of a conductive sheet, a metal casing and a feed element in a tablet mode according to an embodiment of the invention. As shown in FIG. 2A, in the tablet mode, the planes of the conductive sheet 160, the metal casing 110 and the feeding element 170 are substantially parallel to each other, and the slot 150 is located on the conductive sheet 160 and the feeding element. Between 170. Further, in the tablet mode, the orthographic projection of the conductive sheet 160 and the feed element 170 on the metal housing 110 will be as shown in FIG. 2B.
值得一提的是，在平板電腦模式下，亦即當金屬殼體110面對絕緣殼體120時，導電片160在金屬殼體110上的正投影大於並重疊於金屬殼體110上的槽孔150，且導電片160可用以調整金屬殼體110與饋入元件170所形成之開槽孔天線的共振頻率。具體而言，槽孔150為一開槽孔。舉例來說，金屬殼體110包括相鄰的第一邊緣211與第二邊緣212。槽孔150的沿著第一邊緣211延伸，且槽孔150的開口位在第二邊緣212。It is worth mentioning that in the tablet mode, that is, when the metal casing 110 faces the insulating casing 120, the orthographic projection of the conductive sheet 160 on the metal casing 110 is larger than and overlaps the groove on the metal casing 110. The hole 150, and the conductive sheet 160 can be used to adjust the resonant frequency of the slotted hole antenna formed by the metal housing 110 and the feed element 170. Specifically, the slot 150 is a slotted hole. For example, the metal housing 110 includes adjacent first and second edges 211, 212. The slot 150 extends along the first edge 211 and the opening of the slot 150 is at the second edge 212.
饋入元件170沿著平行於第二邊緣212的方向橫跨槽孔150。此外，饋入元件170的第一端具有饋入點FP1，且饋入元件170的第二端為開路端(open end)。在操作上，饋入元件170可透過同軸纜線電性連接至行動電子裝置100中的收發器(未繪示出)。其中，同軸纜線的內導體電性連接至饋入點FP1，且同軸纜線的外導體電性可連接至基板180上所設置的接地元件(未繪示出)。饋入元件170可透過同軸纜線接收到來自收發器的饋入訊號，且饋入元件170可將饋入訊號耦合至槽孔150。藉此，在饋入訊號的激發下，槽孔150將可產生一共振模態，以操作在一共振頻率。其中，槽孔150的長度220為所述共振頻率的1/4波長。The feed element 170 spans the slot 150 in a direction parallel to the second edge 212. Furthermore, the first end of the feed element 170 has a feed point FP1 and the second end of the feed element 170 is an open end. In operation, the feed component 170 can be electrically coupled to a transceiver (not shown) in the mobile electronic device 100 via a coaxial cable. The inner conductor of the coaxial cable is electrically connected to the feeding point FP1, and the outer conductor of the coaxial cable is electrically connected to a grounding element (not shown) provided on the substrate 180. The feed component 170 can receive the feed signal from the transceiver through the coaxial cable, and the feed component 170 can couple the feed signal to the slot 150. Thereby, the slot 150 will generate a resonant mode to operate at a resonant frequency upon excitation of the feed signal. The length 220 of the slot 150 is 1/4 wavelength of the resonant frequency.
除此之外，當金屬殼體110面對絕緣殼體120時，金屬殼體110與導電片160將可形成寄生電容，且所述寄生電容可用以調整開槽孔天線的阻抗(例如，開槽孔天線本身的電容值)，從而可以調整開槽孔天線的共振頻率。值得一提的是，導電片160不具有任何的孔洞(例如，破孔、貫孔或是開口)，進而致使開槽孔天線不會響應導電片160而產生另外的共振模態。換言之，開槽孔天線不會響應於導電片160而產生另外的共振模態。此外，開槽孔天線的阻抗可響應於導電片160而產生改變，進而可調整開槽孔天線的共振頻率。如此一來，導電片160將可用於微調開槽孔天線的共振頻率，從而可以避免行動電子裝置100中的金屬元件對開槽孔天線所造成的影響。In addition, when the metal casing 110 faces the insulating casing 120, the metal casing 110 and the conductive sheet 160 will form a parasitic capacitance, and the parasitic capacitance can be used to adjust the impedance of the slotted antenna (for example, The capacitance of the slot antenna itself), so that the resonant frequency of the slotted antenna can be adjusted. It is worth mentioning that the conductive sheet 160 does not have any holes (for example, holes, through holes or openings), so that the slotted antenna does not respond to the conductive sheet 160 to generate another resonant mode. In other words, the slotted antenna does not respond to the conductive strip 160 to create an additional resonant mode. In addition, the impedance of the slotted antenna can be varied in response to the conductive strip 160, thereby adjusting the resonant frequency of the slotted antenna. In this way, the conductive sheet 160 can be used to finely adjust the resonant frequency of the slotted antenna, so that the influence of the metal components in the mobile electronic device 100 on the slotted antenna can be avoided.
舉例來說，行動電子裝置100的第二機體102內設有多個金屬元件，例如：硬碟、喇叭單體、磁體、系統電路板上的電子元件、系統接地面以及用於靜電放電(ESD)防護的金屬層…等。以作為ESD防護的金屬層為例來看，圖3為依照本發明的一實施例的絕緣殼體的示意圖。如圖3所示，金屬層310可透過濺鍍方式形成在絕緣殼體120的內壁，且導電片160也貼附在絕緣殼體120的內壁。此外，導電片160與金屬層310電性不相連。金屬層310電性連接至第二機體102中的系統接地面，並可用以降低靜電放電對行動電子裝置100所造成的損害。For example, the second body 102 of the mobile electronic device 100 is provided with a plurality of metal components, such as a hard disk, a speaker unit, a magnet, electronic components on the system circuit board, a system ground plane, and an electrostatic discharge (ESD). ) protective metal layer...etc. Taking a metal layer as an ESD shield as an example, FIG. 3 is a schematic view of an insulating case in accordance with an embodiment of the present invention. As shown in FIG. 3, the metal layer 310 is formed on the inner wall of the insulating case 120 by sputtering, and the conductive sheet 160 is also attached to the inner wall of the insulating case 120. In addition, the conductive sheet 160 is electrically disconnected from the metal layer 310. The metal layer 310 is electrically connected to the system ground plane in the second body 102 and can be used to reduce damage caused by the electrostatic discharge to the mobile electronic device 100.
更進一步來看，當第一機體101與第二機體102相對地翻轉而相互重疊時，亦即當金屬殼體110面對絕緣殼體120時，金屬殼體110將較為接近第二機體102內的金屬元件(例如，金屬層310)。此時，第二機體102內的金屬元件對於開槽孔天線之共振頻率所造成的頻率偏移可透過導電片160來進行調整，從而避免金屬元件對於開槽孔天線所造成的影響，並有助於提升行動電子裝置100的通訊品質。Further, when the first body 101 and the second body 102 are oppositely inverted and overlap each other, that is, when the metal casing 110 faces the insulating casing 120, the metal casing 110 will be closer to the second body 102. Metal component (eg, metal layer 310). At this time, the frequency offset caused by the metal component in the second body 102 to the resonant frequency of the slotted antenna can be adjusted through the conductive strip 160, thereby avoiding the influence of the metal component on the slotted antenna, and Helps improve the communication quality of the mobile electronic device 100.
請繼續參照圖2B，槽孔150的形狀可例如是直線型，且饋入元件170的形狀可例如是倒L字型，亦即饋入元件170可例如是倒L字型的金屬片。此外，在平板電腦模式下，亦即當金屬殼體110面對絕緣殼體120時，導電片160在金屬殼體110上的正投影重疊於金屬殼體110的第一邊緣211與第二邊緣212。換言之，導電片160在金屬殼體110上的正投影可覆到蓋金屬殼體110中鄰近槽孔150的兩邊緣211與212，進而致使導電片160在金屬殼體110上的正投影可完全地覆蓋槽孔150。Continuing to refer to FIG. 2B, the shape of the slot 150 can be, for example, a straight line, and the shape of the feed element 170 can be, for example, an inverted L shape, that is, the feed element 170 can be, for example, an inverted L-shaped metal piece. In addition, in the tablet mode, that is, when the metal casing 110 faces the insulating casing 120, the orthographic projection of the conductive sheet 160 on the metal casing 110 overlaps the first edge 211 and the second edge of the metal casing 110. 212. In other words, the orthographic projection of the conductive sheet 160 on the metal casing 110 can cover the two edges 211 and 212 of the cover metal casing 110 adjacent to the slot 150, thereby causing the orthographic projection of the conductive sheet 160 on the metal casing 110 to be completely completed. The ground covers the slot 150.
在一實施例中，導電片160在金屬殼體110上之正投影的長度231等於或是大於共振頻率的1/2波長，且導電片160在金屬殼體110上之正投影的寬度232等於或是大於共振頻率的1/2波長。以頻段為2.4GHz為例進行說明，導電片160在金屬殼體110上之正投影的長度231等於或是大於45毫米，且導電片160在金屬殼體110上之正投影的寬度232等於或是大於45毫米。在一較佳實施例中，導電片160的形狀為正方形，且導電片160在金屬殼體110上之正投影的長度231與寬度232皆相等於共振頻率的1/2波長。雖然圖2B實施例列舉了導電片160的形狀，但是其並非用以限定本發明。舉例來說，導電片160的形狀也可例如是矩形、梯形、圓形、橢圓形或是倒三角形。In one embodiment, the length 231 of the orthographic projection of the conductive sheet 160 on the metal housing 110 is equal to or greater than 1/2 wavelength of the resonant frequency, and the width 232 of the orthographic projection of the conductive sheet 160 on the metal housing 110 is equal to Or greater than 1/2 wavelength of the resonant frequency. Taking the frequency band of 2.4 GHz as an example, the length 231 of the orthographic projection of the conductive sheet 160 on the metal casing 110 is equal to or greater than 45 mm, and the width 232 of the orthographic projection of the conductive sheet 160 on the metal casing 110 is equal to or It is larger than 45 mm. In a preferred embodiment, the conductive sheet 160 is square in shape, and the length 231 and width 232 of the orthographic projection of the conductive sheet 160 on the metal housing 110 are equal to 1/2 wavelength of the resonant frequency. Although the embodiment of FIG. 2B exemplifies the shape of the conductive sheet 160, it is not intended to limit the invention. For example, the shape of the conductive sheet 160 may also be, for example, a rectangle, a trapezoid, a circle, an ellipse, or an inverted triangle.
圖4是依照本發明的一實施例的開槽孔天線的S參數(S11)圖，其中曲線410與曲線420分別為在未設置導電片160以及在加入導電片160下的S參數(S11)。圖5是依照本發明的一實施例的開槽孔天線的史密斯圖，其中圖5的左半部與右半部分別為在未設置導電片160以及在加入導電片160下的史密斯圖。如圖4所示，隨著導電片160的加入，開槽孔天線將可共振在正確或是應用所需的頻段(例如，2.4GHz頻段)，且如圖5所示，開槽孔天線在2.4GHz的阻抗可響應於導電片160而更加地靠近50歐姆。4 is an S-parameter (S11) diagram of a slotted antenna according to an embodiment of the present invention, wherein the curve 410 and the curve 420 are S parameters (S11) in which the conductive sheet 160 is not disposed and the conductive sheet 160 is added, respectively. . 5 is a Smith chart of a slotted antenna in accordance with an embodiment of the present invention, wherein the left and right halves of FIG. 5 are Smith charts, respectively, without the conductive strip 160 and under the conductive strip 160.

更進一步來看，圖6為依照本發明的一實施例的開槽孔天線的輻射效率圖，其中曲線610與曲線620分別是用以表示在未設置導電片160以及在加入導電片160下的輻射效率。圖7為依照本發明的一實施例的開槽孔天線的輻射場型圖，其中圖7的左半部與右半部分別為在未設置導電片160以及在加入導電片160下的輻射場型。如圖6所示，開槽孔天線在2.4GHz的輻射效率可隨著導電片160的設置而增加0.5dB~1dB。此外，由於導電片160可視為開槽孔天線的一部分，因此導電片160也有助於改善開槽孔天線的輻射場型。舉例來說，如圖7所示，開槽孔天線的輻射場型也可響應於導電片160而更具有全向性。Further, FIG. 6 is a graph showing the radiation efficiency of the slotted antenna according to an embodiment of the present invention, wherein the curves 610 and 620 are respectively used to indicate that the conductive sheet 160 is not disposed and the conductive sheet 160 is added.

As shown in FIG. 6, the radiation efficiency of the slotted antenna at 2.4 GHz may increase by 0.5 dB to 1 dB with the setting of the conductive sheet 160. In addition, since the conductive sheet 160 can be considered as a part of the slotted antenna, the conductive sheet 160 also contributes to improving the radiation pattern of the slotted antenna.

綜上所述，本發明的行動電子裝置可透過金屬殼體上的槽孔來形成開槽孔天線。此外，當金屬殼體面對絕緣殼體時，設置在絕緣殼體上的導電片可用以改變或是調整開槽孔天線的阻抗，進而可調整開槽孔天線的共振頻率。藉此，將可避免行動電子裝置中的金屬元件對開槽孔天線所造成的影響，從而有助於提升行動電子裝置通訊品質。In summary, the mobile electronic device of the present invention can form a slotted hole antenna through a slot in the metal housing.
