近年來，具有金屬質感的可攜式電子裝置受到消費者的青睞。因此，可攜式電子裝置大多設有金屬材質的蓋體或是邊框，以突顯產品的獨特性與外觀設計。然而，可攜式電子裝置中可用以設置天線元件的空間有限。因此，可攜式電子裝置中的天線元件往往容易受到周圍之金屬物體的影響，進而降低可攜式電子裝置的通訊品質。換言之，金屬質感的外觀設計為可攜式電子裝置注入了一股流行時尚感，但是卻也對可攜式電子裝置中的天線設計帶來了更大的挑戰。In recent years, portable electronic devices with metallic texture have been favored by consumers. Therefore, most portable electronic devices are provided with a metal cover or a frame to highlight the uniqueness and design of the product. However, the space available in the portable electronic device to set the antenna elements is limited. Therefore, the antenna elements in the portable electronic device are often susceptible to the surrounding metal objects, thereby reducing the communication quality of the portable electronic device.

Furthermore, the two resonant paths in the antenna element share the first radiator and the second radiator, which in turn helps to reduce the size of the antenna element.

圖1為依據本發明一實施例之可攜式電子裝置的示意圖。如圖1所示，可攜式電子裝置100包括基板110、接地面120與天線元件130。其中，接地面120與天線元件130設置在基板110的一表面111上。換言之，天線元件130可例如是一平面天線。此外，接地面120包括相鄰的第一邊緣SD11與第二邊緣SD12。天線元件130包括第一輻射體131、第二輻射體132、第三輻射體133與第四輻射體134。FIG. 1 is a schematic diagram of a portable electronic device according to an embodiment of the invention. As shown in FIG. 1 , the portable electronic device 100 includes a substrate 110 , a ground plane 120 , and an antenna element 130 . The ground plane 120 and the antenna element 130 are disposed on a surface 111 of the substrate 110. In other words, antenna element 130 can be, for example, a planar antenna. Further, the ground plane 120 includes an adjacent first edge SD11 and a second edge SD12. The antenna element 130 includes a first radiator 131, a second radiator 132, a third radiator 133, and a fourth radiator 134.
第一輻射體131的形狀呈十字形，並具有第一端至第四端T11~T14。其中，第一輻射體131的第一端至第四端T11~T14沿著順時針方向依序環繞第一輻射體131的中心點。此外，第一輻射體131的第一端T11具有一饋入點FP1，以接收來自可攜式電子裝置100中之收發器(未繪示出)的饋入訊號。第二輻射體132電性連接第一輻射體131的第二端T12與接地面120的第二邊緣SD12，且第二輻射體132平行於接地面120的第一邊緣SD11。第三輻射體133電性連接第一輻射體131的第二端T12與第三端T13。第四輻射體134電性連接第一輻射體131的第一端T11與第四端T14。The first radiator 131 has a cross shape and has first to fourth ends T11 to T14. The first end to the fourth end T11 T T14 of the first radiator 131 sequentially surround the center point of the first radiator 131 in a clockwise direction. In addition, the first end T11 of the first radiator 131 has a feed point FP1 for receiving a feed signal from a transceiver (not shown) in the portable electronic device 100. The second radiator 132 is electrically connected to the second end T12 of the first radiator 131 and the second edge SD12 of the ground plane 120 , and the second radiator 132 is parallel to the first edge SD11 of the ground plane 120 . The third radiator 133 is electrically connected to the second end T12 and the third end T13 of the first radiator 131. The fourth radiator 134 is electrically connected to the first end T11 and the fourth end T14 of the first radiator 131.
值得注意的是，第一輻射體131、第二輻射體132與第三輻射體133可形成從饋入點FP1至接地面120的第一共振路徑。第一輻射體131、第二輻射體132與第四輻射體134可形成從饋入點FP1至接地面120的第二共振路徑。此外，天線元件130可透過第一共振路徑與第二共振路徑操作在第一頻段與第二頻段。It should be noted that the first radiator 131, the second radiator 132 and the third radiator 133 may form a first resonance path from the feeding point FP1 to the ground plane 120. The first radiator 131, the second radiator 132, and the fourth radiator 134 may form a second resonance path from the feed point FP1 to the ground plane 120. In addition, the antenna element 130 can operate in the first frequency band and the second frequency band through the first resonant path and the second resonant path.
舉例來說，圖2為依據本發明一實施例之用以說明天線元件的示意圖。如圖2所示，第一輻射體131包括中心部210以及第一延伸部至第四延伸部221~224。其中，第一延伸部至第四延伸部221~224電性連接中心部210，並沿著順時針方向依序環繞中心部210。此外，第一延伸部221與第三延伸部223平行於接地面120的第一邊緣SD11，並用以形成第一輻射體131的第一端T11與第三端T13。第二延伸部222與第四延伸部224平行於接地面120的第二邊緣SD12，並用以形成第一輻射體131的第二端T12與第四端T14。For example, FIG. 2 is a schematic diagram illustrating an antenna element in accordance with an embodiment of the present invention. As shown in FIG. 2, the first radiator 131 includes a center portion 210 and first to fourth extension portions 221 to 224. The first to fourth extensions 221 - 224 are electrically connected to the central portion 210 and sequentially surround the central portion 210 in a clockwise direction. In addition, the first extending portion 221 and the third extending portion 223 are parallel to the first edge SD11 of the ground plane 120 and are used to form the first end T11 and the third end T13 of the first radiator 131. The second extension portion 222 and the fourth extension portion 224 are parallel to the second edge SD12 of the ground plane 120 and are used to form the second end T12 and the fourth end T14 of the first radiator 131.
第一延伸部221設置在第二輻射體132與第四輻射體134之間，且第二延伸部222設置在第二輻射體132與第三輻射體133。第二輻射體132的第一端電性連接第二延伸部222，且第二輻射體132的第二端具有一接地點GP1，以電性連接至接地面120的第二邊緣SD12。第三輻射體133的第一端電性連接第三延伸部223，且第三輻射體133的第二端電性連接第二延伸部222。藉此，第二延伸部222、第三延伸部223與第三輻射體133將可形成一封閉開口201。另一方面，第四輻射體134的第一端電性連接第四延伸部224，且第四輻射體134的第二端電性連接第一延伸部221。藉此，第一延伸部221、第四延伸部224與第四輻射體134將可形成一封閉開口202。The first extension portion 221 is disposed between the second radiator 132 and the fourth radiator 134, and the second extension portion 222 is disposed between the second radiator 132 and the third radiator 133. The first end of the second radiator 132 is electrically connected to the second extension portion 222 , and the second end of the second radiator 132 has a grounding point GP1 to be electrically connected to the second edge SD12 of the ground plane 120 . The first end of the third radiator 133 is electrically connected to the third extension 223 , and the second end of the third radiator 133 is electrically connected to the second extension 222 . Thereby, the second extension portion 222, the third extension portion 223 and the third radiator 133 will form a closed opening 201. On the other hand, the first end of the fourth radiator 134 is electrically connected to the fourth extension 224 , and the second end of the fourth radiator 134 is electrically connected to the first extension 221 . Thereby, the first extension portion 221, the fourth extension portion 224 and the fourth radiator 134 will form a closed opening 202.
更進一步來看，第一延伸部221、中心部210、第三延伸部223、第三輻射體133、部分之第二延伸部222以及第二輻射體132，將可形成從饋入點FP1延伸至接地面120(亦即，接地點GP1)的第一共振路徑230。另一方面，第四輻射體134、第四延伸部224、中心部210、第二延伸部222以及第二輻射體132，將可形成從饋入點FP1延伸至接地面120(亦即，接地點GP1)的第二共振路徑240。此外，第一共振路徑230與第二共振路徑240都是沿著同一方向(亦即，逆時針方向)從饋入點FP1延伸至接地面120(亦即，接地點GP1)。再者，天線元件130可透過第一共振路徑230操作在第一頻段，並可透過第二共振路徑240操作在第二頻段。Further, the first extension portion 221, the central portion 210, the third extension portion 223, the third radiator 133, a portion of the second extension portion 222, and the second radiator 132 may be formed to extend from the feed point FP1. The first resonant path 230 to the ground plane 120 (ie, the ground point GP1). On the other hand, the fourth radiator 134, the fourth extension portion 224, the central portion 210, the second extension portion 222, and the second radiator 132 may be formed to extend from the feed point FP1 to the ground plane 120 (ie, The second resonant path 240 of the location GP1). Further, both the first resonant path 230 and the second resonant path 240 extend from the feed point FP1 to the ground plane 120 (ie, the ground point GP1) in the same direction (ie, counterclockwise direction). Moreover, the antenna element 130 can operate in the first frequency band through the first resonant path 230 and can operate in the second frequency band through the second resonant path 240.
值得一提的是，在一實施例中，天線元件130更可額外設置兩輻射體，以藉此增加第二頻段的頻寬。舉例來說，如圖1與圖2所示，天線元件130更包括第五輻射體135與第六輻射體136。其中，第五輻射體135設置在封閉開口202內。此外，第五輻射體135的第一端電性連接第四輻射體134，且第五輻射體135的第二端為一開路端。It is worth mentioning that, in an embodiment, the antenna element 130 can additionally provide two radiators to thereby increase the bandwidth of the second frequency band. For example, as shown in FIG. 1 and FIG. 2, the antenna element 130 further includes a fifth radiator 135 and a sixth radiator 136. The fifth radiator 135 is disposed in the closed opening 202. In addition, the first end of the fifth radiator 135 is electrically connected to the fourth radiator 134, and the second end of the fifth radiator 135 is an open end.
再者，第五輻射體135的第一端鄰近第四輻射體134的彎折處，且第五輻射體135的第二端朝向中心部210延伸，進而致使第五輻射體135與第四輻射體134相交一夾角θ2。第六輻射體136的第一端電性連接第四延伸部224，且第六輻射體136的第二端為一開路端。此外，第六輻射體136平行於第三延伸部223。在操作上，天線元件130可透過第五輻射體135與第六輻射體136來擴展其所涵蓋之第二頻段的頻寬。Furthermore, the first end of the fifth radiator 135 is adjacent to the bend of the fourth radiator 134, and the second end of the fifth radiator 135 extends toward the central portion 210, thereby causing the fifth radiator 135 and the fourth radiation. The bodies 134 intersect at an angle θ2. The first end of the sixth radiator 136 is electrically connected to the fourth extension 224, and the second end of the sixth radiator 136 is an open end. Further, the sixth radiator 136 is parallel to the third extension 223. In operation, the antenna element 130 can extend the bandwidth of the second frequency band covered by the fifth radiator 135 and the sixth radiator 136.
舉例來說，圖3為依據本發明一實施例之天線元件在未加入第五輻射體與第六輻射體時的返回損失曲線圖，且圖4為依據本發明一實施例之天線元件在加入第五輻射體與第六輻射體時的返回損失曲線圖。在圖3與圖4實施例中，天線元件130的長度L1約為27mm，且天線元件130的寬度W1約為6.5mm。For example, FIG. 3 is a graph showing return loss of an antenna element when a fifth radiator and a sixth radiator are not added according to an embodiment of the present invention, and FIG. 4 is an antenna component according to an embodiment of the present invention. Return loss graph of the fifth radiator and the sixth radiator. In the embodiment of Figures 3 and 4, the length L1 of the antenna element 130 is about 27 mm and the width W1 of the antenna element 130 is about 6.5 mm.
如圖3所示，天線元件130可透過第一共振路徑產生一低頻模態，且所述低頻模態涵蓋2.4GHz~2.5GHz。此外，天線元件130可透過第二共振路徑產生一高頻模態。如圖4所示，在加入第五輻射體135與第六輻射體136的情況下，天線元件130依舊可產生涵蓋2.4GHz~2.5GHz的低頻模態。此外，第五輻射體135與第六輻射體136可擴展天線元件130在高頻模態下的頻寬，進而致使天線元件130的高頻模態可涵蓋5.15GHz~5.85GHz。再者，天線元件130在2.4GHz~2.5GHz下的輻射效率皆可在-2.8dB以上，且天線元件130在5.15GHz~5.85GHz下的輻射效率皆可在-3.1dB以上。As shown in FIG. 3, the antenna element 130 can generate a low frequency mode through the first resonant path, and the low frequency mode covers 2.4 GHz to 2.5 GHz. In addition, the antenna element 130 can generate a high frequency mode through the second resonant path. As shown in FIG. 4, in the case where the fifth radiator 135 and the sixth radiator 136 are added, the antenna element 130 can still generate a low frequency mode covering 2.4 GHz to 2.5 GHz. In addition, the fifth radiator 135 and the sixth radiator 136 can expand the bandwidth of the antenna element 130 in the high frequency mode, thereby causing the high frequency mode of the antenna element 130 to cover 5.15 GHz to 5.85 GHz. Furthermore, the radiation efficiency of the antenna element 130 at 2.4 GHz to 2.5 GHz can be above -2.8 dB, and the radiation efficiency of the antenna element 130 at 5.15 GHz to 5.85 GHz can be above -3.1 dB.
請繼續參照圖1與圖2。第一延伸部至第四延伸部221~224以及第二輻射體至第六輻射體132~136可分別由一金屬線所構成。此外，第三輻射體133與第四輻射體134的形狀可例如是倒L形。再者，天線元件130可透過第一共振路徑與第二共振路徑形成雙迴路(loop)。換言之，天線元件130相當於具有雙迴路結構的環形天線(loop antenna)。舉例來說，圖5為依據本發明一實施例之天線元件在第一頻段下的輻射場型圖。如圖5所示，天線元件130在2.4GHz、2.45GHz與2.5GHz下的輻射場型可朝向前後輻射，且所述輻射場型在左右兩側的凹陷最深也僅達-5dB左右。換言之，天線元件130的輻射場型符合環形天線的特性，且天線元件130在各個角度上皆能接收到訊號。Please continue to refer to Figure 1 and Figure 2. The first to fourth extensions 221 to 224 and the second to sixth radiators 132 to 136 may each be composed of a metal wire. Further, the shapes of the third radiator 133 and the fourth radiator 134 may be, for example, an inverted L shape. Furthermore, the antenna element 130 can form a loop through the first resonant path and the second resonant path. In other words, the antenna element 130 corresponds to a loop antenna having a double loop structure. For example, FIG. 5 is a radiation pattern diagram of an antenna element in a first frequency band according to an embodiment of the invention. As shown in FIG. 5, the radiation pattern of the antenna element 130 at 2.4 GHz, 2.45 GHz, and 2.5 GHz can be radiated toward the front and rear, and the depth of the radiation field on the left and right sides is only about -5 dB. In other words, the radiation pattern of the antenna element 130 conforms to the characteristics of the loop antenna, and the antenna element 130 can receive signals at various angles.
值得一提的是，具有迴路結構的天線元件130本身具有較高的電感性，因此可以提高天線元件130抵抗金屬干擾的能力。換言之，具有迴路結構的天線元件130具有較佳的抗金屬能力，從而有助於提升可攜式電子裝置100的通訊品質。除此之外，天線元件130中的雙迴路(亦即，兩共振路徑)是共用相同的饋入點FP1與接地點GP1，並共用第一輻射體131與第二輻射體132。因此，可有效地縮減天線元件130的尺寸，從而有助於可攜式電子裝置100的微型化。此外，在一實施例中，可藉由改變第三延伸部223與第三輻射體133的長度來獨立調整第一共振路徑的長度，並可藉由改變第四延伸部224與第四輻射體134的長度來獨立調整第二共振路徑的長度。換言之，天線元件130中的第一共振路徑與第二共振路徑可分別獨立調整，進而有助於降低天線元件130之高頻與低頻特性之間的相互影響。It is worth mentioning that the antenna element 130 having a loop structure itself has a high inductance, so that the ability of the antenna element 130 to resist metal interference can be improved. In other words, the antenna element 130 having the loop structure has better metal resistance, thereby contributing to improving the communication quality of the portable electronic device 100. In addition, the two loops (that is, the two resonance paths) in the antenna element 130 share the same feed point FP1 and the ground point GP1, and share the first radiator 131 and the second radiator 132. Therefore, the size of the antenna element 130 can be effectively reduced, thereby contributing to miniaturization of the portable electronic device 100. In addition, in an embodiment, the length of the first resonant path can be independently adjusted by changing the lengths of the third extending portion 223 and the third radiating body 133, and the fourth extending portion 224 and the fourth radiator can be changed by The length of 134 is used to independently adjust the length of the second resonant path. In other words, the first resonant path and the second resonant path in the antenna element 130 can be independently adjusted, thereby helping to reduce the interaction between the high frequency and low frequency characteristics of the antenna element 130.
圖6為依據本發明一實施例之可攜式電子裝置的外觀示意圖。如圖6所示，可攜式電子裝置100可例如是一筆記型電腦，且可攜式電子裝置100更包括第一機體610、第二機體620與樞軸630。其中，樞軸630連接在第一機體610與第二機體620之間，且第一機體610與第二機體620可藉由樞軸630而相對轉動，以切換至展開狀態或是閉合狀態。FIG. 6 is a schematic diagram of the appearance of a portable electronic device according to an embodiment of the invention. As shown in FIG. 6 , the portable electronic device 100 can be, for example, a notebook computer, and the portable electronic device 100 further includes a first body 610 , a second body 620 , and a pivot 630 . The pivot 630 is connected between the first body 610 and the second body 620, and the first body 610 and the second body 620 are relatively rotated by the pivot 630 to switch to the deployed state or the closed state.
更進一步來看，第一機體610包括第一蓋體與第一邊框，以構成相對的第一表面611與第二表面612。具體而言，第一蓋體可用以構成第一機體610的第一表面611。第一邊框可用以構成第一機體610的第二表面612，且第一邊框環繞配置在第一機體610上的顯示器640。另一方面，第二機體620包括第二蓋體與第二邊框，以構成相對的第三表面621與第四表面622。其中，第二邊框可用以構成第二機體620的第三表面，且第二邊框環繞配置在第二機體620上的鍵盤650與觸控板660。此外，第二蓋體可用以構成第二機體620的第四表面622。In further detail, the first body 610 includes a first cover and a first frame to form an opposite first surface 611 and second surface 612. Specifically, the first cover may be used to constitute the first surface 611 of the first body 610. The first frame can be used to form the second surface 612 of the first body 610, and the first frame surrounds the display 640 disposed on the first body 610. On the other hand, the second body 620 includes a second cover and a second frame to form an opposite third surface 621 and fourth surface 622. The second frame can be used to form the third surface of the second body 620 , and the second frame surrounds the keyboard 650 and the touch pad 660 disposed on the second body 620 . Further, the second cover may be used to constitute the fourth surface 622 of the second body 620.
圖7為依據本發明一實施例之第二機體與樞軸的示意圖。如圖7所示，第二機體620包括承載區域710，且樞軸630設置在承載區域710內。此外，當第一機體610相對於第二機體620展開時，第一機體610可豎立在承載區域710的上方。值得一提的是，在一實施例中，第一蓋體、第一邊框、第二蓋體與第二邊框可分別由金屬材質所構成。此外，天線元件130可設置在第二機體620的承載區域710內，並鄰近承載區域710內的樞軸630。由於天線元件130具有較佳的抗金屬能力，因此可攜式電子裝置100依舊可保有良好的通訊品質。7 is a schematic view of a second body and a pivot according to an embodiment of the invention. As shown in FIG. 7, the second body 620 includes a load bearing area 710, and the pivot 630 is disposed within the load bearing area 710. In addition, when the first body 610 is deployed relative to the second body 620, the first body 610 can be erected above the load bearing area 710. It is to be noted that, in an embodiment, the first cover, the first frame, the second cover, and the second frame may each be made of a metal material. Additionally, the antenna element 130 can be disposed within the load bearing region 710 of the second body 620 and adjacent to the pivot 630 within the load bearing region 710. Since the antenna element 130 has better metal resistance, the portable electronic device 100 can still maintain good communication quality.
綜上所述，本發明的可攜式電子裝置可利用天線元件中的兩共振路徑形成雙迴路，以致使天線元件具有較佳的抗金屬能力，從而有助於提升可攜式電子裝置的通訊品質。此外，天線元件中的兩共振路徑共用第一輻射體與第二輻射體，進而有助於縮減天線元件的尺寸。再者，天線元件中的兩共振路徑可分別獨立調整，進而有助於降低天線元件之高頻與低頻特性之間的相互影響。In summary, the portable electronic device of the present invention can form a double loop by using two resonant paths in the antenna element, so that the antenna element has better metal resistance, thereby helping to improve communication of the portable electronic device. quality. Furthermore, the two resonant paths in the antenna element share the first radiator and the second radiator, which in turn helps to reduce the size of the antenna element. Moreover, the two resonant paths in the antenna element can be independently adjusted, thereby helping to reduce the interaction between the high frequency and low frequency characteristics of the antenna element.
