天線是無線通訊裝置中不可或缺的一重要元件，且其性能直接攸關無線通訊裝置的通訊品質。隨著消費者對通訊產品之功能需求的多樣化，無線通訊裝置往往必須內建多個天線單元，以同時支援多種無線通訊功能。 The antenna is an indispensable component in the wireless communication device, and its performance directly affects the communication quality of the wireless communication device. With the diversification of consumer demand for communication products, wireless communication devices often have to have multiple antenna units built in to support multiple wireless communication functions.
然而，近年來無線通訊裝置的外觀也朝向輕薄短小的方向設計，進而導致無線通訊裝置的硬體空間有限。因此，如何整合無線通訊裝置中的天線單元，並兼顧天線的通訊品質，已是天線在設計上的一大課題。 However, in recent years, the appearance of the wireless communication device has also been designed in a light, short, and short direction, which in turn results in limited hardware space for the wireless communication device. Therefore, how to integrate the antenna unit in the wireless communication device and the communication quality of the antenna is a major issue in the design of the antenna.
本發明提供一種整合式天線，用以縮間天線的硬體空間，並兼顧天線的通訊品質。 The invention provides an integrated antenna for shrinking the hardware space of the antenna and taking into consideration the communication quality of the antenna.
本發明的整合式天線，包括第一接地部、第二接地部、延伸接地部以及輻射單元。第一接地部與第二接地部從一接地面延伸而出，並形成第一共振路徑與第二共振路徑。延伸接地部從第一接地部延伸而出，且延伸接地部與部分的第一接地部形成第三共振路徑。輻射單元透過一耦合方式激發第一接地部、第二接地部與延伸接地部，以致使整合式天線操作在至少一延伸頻帶。此外，第一接地部隔離延伸接地部與第二接地部之間的耦合效應。 The integrated antenna of the present invention includes a first ground portion, a second ground portion, an extended ground portion, and a radiating unit. The first ground portion and the second ground portion extend from a ground plane to form a first resonant path and a second resonant path. The extended ground portion extends from the first ground portion, and the extended ground portion forms a third resonant path with the portion of the first ground portion. The radiating unit excites the first ground portion, the second ground portion and the extended ground portion by a coupling manner to cause the integrated antenna to operate in at least one extended frequency band. Further, the first ground portion isolates a coupling effect between the extended ground portion and the second ground portion.
基於上述，本發明的第一接地部與第二接地部是從一接地面延伸而出，且延伸接地部是從第一接地部延伸而出。此外，本發明更利用輻射單元激發第一接地部、第二接地部與延伸接地部。藉此，將有助於縮減整合式天線的硬體空間。再者，第一接地部還可用以作為第二接地部與延伸接地部之間的隔離元件，進而有助於增加整合式天線的通訊品質。 Based on the above, the first ground portion and the second ground portion of the present invention extend from a ground plane, and the extended ground portion extends from the first ground portion. In addition, the present invention further utilizes the radiating element to excite the first ground portion, the second ground portion, and the extended ground portion. This will help to reduce the hardware space of the integrated antenna. Furthermore, the first ground portion can also be used as an isolation component between the second ground portion and the extended ground portion, thereby contributing to increase the communication quality of the integrated antenna.

圖1為依據本發明一實施例之整合式天線的架構示意圖。參照圖1，整合式天線100包括第一接地部110、第二接地部120、延伸接地部130以及輻射單元140，且輻射單元140包括第一輻射部141與第二輻射部142。 FIG. 1 is a schematic structural diagram of an integrated antenna according to an embodiment of the invention. Referring to FIG. 1 , the integrated antenna 100 includes a first ground portion 110 , a second ground portion 120 , an extended ground portion 130 , and a radiating unit 140 , and the radiating unit 140 includes a first radiating portion 141 and a second radiating portion 142 .
第一接地部110與第二接地部120是從接地面150延伸而出。延伸接地部130則是從第一接地部110延伸而出。換言之，本實施例之第一接地部110與第二接地部120是直接電性連接至接地面150，而延伸接地部130則是透過第一接地部110電性連接至接地面150。因此，從另一角度來看，延伸接地部130與第一接地部110是共用同一接地點GP1，而第二接地部120則是具有另一接地點GP2。 The first ground portion 110 and the second ground portion 120 extend from the ground plane 150. The extended ground portion 130 extends from the first ground portion 110. In other words, the first ground portion 110 and the second ground portion 120 of the present embodiment are directly electrically connected to the ground plane 150 , and the extended ground portion 130 is electrically connected to the ground plane 150 through the first ground portion 110 . Therefore, from another point of view, the extended ground portion 130 and the first ground portion 110 share the same ground point GP1, and the second ground portion 120 has another ground point GP2.
更進一步來看，第一接地部110可形成第一共振路徑PT1，且第二接地部120可形成第二共振路徑PT2。此外，延伸接地部130與部分的第一接地部110可形成第二共振路徑PT3。另一方面，輻射單元140會透過一耦合方式來激發第一接地部110、第二接地部120與延伸接地部130。藉此，整合式天線100將可透過第一至第三共振路徑PT1~PT3產生多個共振模態，進而操作在至少一延伸頻帶下。 Further, the first ground portion 110 may form the first resonant path PT1, and the second ground portion 120 may form the second resonant path PT2. Further, the extended ground portion 130 and a portion of the first ground portion 110 may form a second resonant path PT3. On the other hand, the radiating unit 140 excites the first ground portion 110, the second ground portion 120, and the extended ground portion 130 through a coupling manner. Thereby, the integrated antenna 100 can generate a plurality of resonant modes through the first to third resonant paths PT1 PT3, and further operate in at least one extended frequency band.
舉例來說，第一輻射部141具有第一饋入點FP1，以接收第一饋入訊號。此外，來自第一輻射部141的第一饋入訊號會耦 合至第一接地部110與第二接地部120。藉此，整合式天線100將可透過第一共振路徑PT1產生第一共振模態，進而操作在第一延伸頻帶(例如，LTE 700)下。此外，整合式天線100也可透過第二共振路徑PT2產生第二共振模態，進而操作在第二延伸頻帶(例如，LTE 2600)下。 For example, the first radiating portion 141 has a first feed point FP1 to receive the first feed signal. In addition, the first feed signal from the first radiating portion 141 is coupled The first ground portion 110 and the second ground portion 120 are coupled. Thereby, the integrated antenna 100 will generate a first resonant mode through the first resonant path PT1, and then operate in a first extended frequency band (eg, LTE 700). In addition, the integrated antenna 100 can also generate a second resonant mode through the second resonant path PT2, thereby operating in a second extended frequency band (eg, LTE 2600).
第二輻射部142具有第二饋入點FP2，以接收第二饋入訊號。此外，來自第二輻射部142的第二饋入訊號會耦合至延伸接地部130。藉此，整合式天線100將可透過第三共振路徑PT3產生第三共振模態，進而操作在第三延伸頻帶(例如，2.4GHz)下。此外，整合式天線100是基於四分之一波長的共振機制來產生各個共振模態。因此，第一共振路徑的長度為第一延伸頻帶中一最低頻率的1/4波長，第二共振路徑的長度為第二延伸頻帶中一最低頻率的1/4波長，且第三共振路徑的長度為第三延伸頻帶中一最低頻率的1/4波長。 The second radiating portion 142 has a second feed point FP2 to receive the second feed signal. Additionally, the second feed signal from the second radiating portion 142 is coupled to the extended ground portion 130. Thereby, the integrated antenna 100 will generate a third resonant mode through the third resonant path PT3, and then operate in a third extended frequency band (eg, 2.4 GHz). In addition, the integrated antenna 100 is based on a quarter-wavelength resonance mechanism to generate individual resonant modes. Therefore, the length of the first resonant path is 1/4 wavelength of a lowest frequency in the first extended frequency band, and the length of the second resonant path is 1/4 wavelength of a lowest frequency in the second extended frequency band, and the third resonant path is The length is 1/4 wavelength of a lowest frequency in the third extended frequency band.
整合式天線100也可透過輻射單元140操在至少一操作頻帶。舉例來說，第一輻射部141會形成第四共振路徑PT4。因此，在第一饋入訊號的激發下，第一輻射部141會產生第四共振模態，進而致使整合式天線100可操作在第一操作頻帶(例如，GSM 1800/GSM 1900/WCDMA 2100)。此外，在第二饋入訊號的激發下，第二輻射部142會產生第五共振模態，進而致使整合式天線100可操作在第二操作頻帶(例如，5.8GHz)。在一實施例中，第四共振路徑的長度為第一操作頻帶中一最低頻率的1/4波長，且第五共振 路徑的長度為第二操作頻帶中一最低頻率的1/4波長。 The integrated antenna 100 can also operate in at least one operating band through the radiating element 140. For example, the first radiating portion 141 forms a fourth resonant path PT4. Therefore, under the excitation of the first feed signal, the first radiating portion 141 generates a fourth resonant mode, thereby causing the integrated antenna 100 to operate in the first operating band (eg, GSM 1800/GSM 1900/WCDMA 2100). . In addition, the second radiating portion 142 generates a fifth resonant mode under excitation of the second feed signal, thereby causing the integrated antenna 100 to operate in the second operating band (eg, 5.8 GHz). In an embodiment, the length of the fourth resonant path is 1/4 wavelength of a lowest frequency in the first operating band, and the fifth resonance The length of the path is 1/4 wavelength of a lowest frequency in the second operating band.
換言之，整合式天線100可透過第一輻射部141、第一接地部110與第二接地部120，操作在LTE 700、GSM 1800、GSM 1900、WCDMA 2100、LTE 2600頻帶。因此，第一輻射部141、第一接地部110與第二接地部120可相當於一LTE天線單元。再者，整合式天線100可透過第二輻射部142、延伸接地部130與部分的第一接地部110操作在2.4GHz與5.8GHz頻帶。因此，第二輻射部142與延伸接地部130可相當於一WLAN天線單元。 In other words, the integrated antenna 100 can pass through the first radiating portion 141, the first ground portion 110, and the second ground portion 120, and operates in the LTE 700, GSM 1800, GSM 1900, WCDMA 2100, and LTE 2600 bands. Therefore, the first radiating portion 141, the first ground portion 110, and the second ground portion 120 may correspond to an LTE antenna unit. Furthermore, the integrated antenna 100 can operate in the 2.4 GHz and 5.8 GHz bands through the second radiating portion 142, the extended ground portion 130, and a portion of the first ground portion 110. Therefore, the second radiating portion 142 and the extended ground portion 130 may correspond to a WLAN antenna unit.
值得一提的是，LTE天線單元與WLAN天線單元共用第一接地部110，亦即共用同一接地點GP1。因此，在實體配置上，可以縮減LTE天線單元與WLAN天線單元之間的間距，進而有助於縮減整合式天線100的硬體空間。除此之外，第一接地部110還可用以作為一屏蔽元件，以藉此降低兩天線單元之間的耦合效應。藉此，將可提升兩天線單元的隔離度，進而兼顧整合式天線100的通訊品質。 It is worth mentioning that the LTE antenna unit and the WLAN antenna unit share the first grounding portion 110, that is, share the same grounding point GP1. Therefore, in the physical configuration, the spacing between the LTE antenna unit and the WLAN antenna unit can be reduced, thereby helping to reduce the hardware space of the integrated antenna 100. In addition to this, the first ground portion 110 can also be used as a shielding element to thereby reduce the coupling effect between the two antenna elements. Thereby, the isolation of the two antenna elements can be improved, and the communication quality of the integrated antenna 100 can be achieved.
舉例來說，圖2為依據本發明一實施例之整合式天線的散射參數曲線圖。其中，圖2實施例所列舉之整合式天線的尺寸約為73×12 mm2。此外，曲線210與220分別為LTE天線單元與WLAN天線單元的返回損失。曲線230為兩天線單元的隔離度，且在各個頻帶下的隔離度標示在圖2的右上角。 For example, FIG. 2 is a graph of scattering parameters of an integrated antenna in accordance with an embodiment of the present invention. The integrated antenna listed in the embodiment of Fig. 2 has a size of about 73 × 12 mm 2 . In addition, curves 210 and 220 are the return losses of the LTE antenna unit and the WLAN antenna unit, respectively. Curve 230 is the isolation of the two antenna elements, and the isolation at each frequency band is indicated in the upper right corner of FIG.
另一方面，圖3為現有技術之整合式天線的散射參數曲線圖。其中，圖3中現有技術之整合式天線的尺寸約為90×12 mm2。此外，曲線310與320分別為現有技術之LTE天線單元與WLAN天線單元的返回損失。曲線330為兩天線單元的隔離度，且在各個頻帶下的隔離度標示在圖3的右上角。 On the other hand, Fig. 3 is a graph of scattering parameters of the prior art integrated antenna. Among them, the prior art integrated antenna of Fig. 3 has a size of about 90 x 12 mm 2 . In addition, curves 310 and 320 are the return losses of the prior art LTE antenna unit and WLAN antenna unit, respectively. Curve 330 is the isolation of the two antenna elements, and the isolation at each frequency band is indicated in the upper right corner of FIG.
比較圖2與圖3來看，本實施所列舉的天線結構有助於縮減整合式天線的長度。此外，在圖2中，本實施所列舉之整合式天線的隔離度大多低於-20dB。然而，圖3中現有技術之整合式天線的隔離度大多高於-20dB。換言之，本實施所列舉的天線結構不僅有助於縮減整合式天線的硬體空間，還可提升天線單元之間的隔離度。 Comparing Fig. 2 with Fig. 3, the antenna structure enumerated in this embodiment helps to reduce the length of the integrated antenna. In addition, in FIG. 2, the isolation of the integrated antennas listed in the present embodiment is mostly lower than -20 dB. However, the isolation of the prior art integrated antenna in Fig. 3 is mostly higher than -20 dB. In other words, the antenna structure exemplified in the present embodiment not only helps to reduce the hardware space of the integrated antenna, but also improves the isolation between the antenna elements.
為了致使本領域具有通常知識者能更加瞭解圖1實施例，以下將針對整合式天線100的細部結構進行更進一步地說明。請繼續參照圖1，第一接地部110包括第一區段111與第二區段112。第一區段111的一端具有接地點GP1，並透過接地點GP1電性連接至接地面150的一邊緣151。第一區段111的另一端電性連接至第二區段112。此外，延伸接地部130電性連接第一區段111，且延伸接地部130與第二區段112配置在第一區段111的兩側。 In order to make those skilled in the art more aware of the FIG. 1 embodiment, the detailed structure of the integrated antenna 100 will be further explained below. With continued reference to FIG. 1 , the first ground portion 110 includes a first section 111 and a second section 112 . One end of the first section 111 has a grounding point GP1 and is electrically connected to an edge 151 of the ground plane 150 through the grounding point GP1. The other end of the first section 111 is electrically connected to the second section 112. In addition, the extended grounding portion 130 is electrically connected to the first section 111, and the extended grounding portion 130 and the second section 112 are disposed on both sides of the first section 111.
在整體配置上，第一輻射部141、第二接地部120、第一區段111與第二輻射部142沿著接地面150的邊緣151依序排列。此外，第二區段112位在第一輻射部141與第二接地部120的上方，且第二區段112平行於部分的第一輻射部141與部分的第二接地部120。此外，延伸接地部130位在第二輻射部142的上方，且延伸接地部130平行於部分的第二輻射部142。再者，第一輻射 部141平行於部分的第二接地部120。 In the overall configuration, the first radiating portion 141, the second ground portion 120, the first segment 111 and the second radiating portion 142 are sequentially arranged along the edge 151 of the ground plane 150. Further, the second section 112 is located above the first radiating portion 141 and the second ground portion 120, and the second segment 112 is parallel to the portion of the first radiating portion 141 and a portion of the second ground portion 120. Further, the extended ground portion 130 is located above the second radiating portion 142, and the extended ground portion 130 is parallel to a portion of the second radiating portion 142. Furthermore, the first radiation The portion 141 is parallel to the portion of the second ground portion 120.
藉此，第一輻射部141將可分別與第一接地部110的第二區段112、第二接地部120相隔一耦合間距，以將第一饋入訊號耦合至第二區段112與第二接地部120。此外，第一輻射部141的末端鄰近第二區段112的末端，進而有助於增加兩者之間的耦合效應。此外，第二輻射部142與延伸接地部130也相隔一耦合間距，以將第二饋入訊號耦合至延伸接地部130。相似地，第二輻射部142的末端鄰近延伸接地部130的末端，進而有助於增加兩者之間的耦合效應。 Thereby, the first radiating portion 141 can be separated from the second segment 112 and the second ground portion 120 of the first ground portion 110 by a coupling pitch to couple the first feed signal to the second segment 112 and the first portion. Two grounding portions 120. Further, the end of the first radiating portion 141 is adjacent to the end of the second segment 112, thereby contributing to an increase in the coupling effect between the two. In addition, the second radiating portion 142 and the extended ground portion 130 are also separated by a coupling pitch to couple the second feed signal to the extended ground portion 130. Similarly, the end of the second radiating portion 142 is adjacent to the end of the extended ground portion 130, thereby contributing to an increase in the coupling effect between the two.
更進一步來看，圖1中的第一輻射部141、第一接地部110、第二接地部120與第二輻射部142的形狀可例如為L型，但其並非用以限定本發明。此外，如圖1所示，在一實施例中，整合式天線100更包括一基板160，且第一接地部110、第二接地部120、延伸接地部130以及輻射單元140皆設置在基板160的一表面161上。換言之，整合式天線100可相當於一平面天線。 Further, the shape of the first radiating portion 141, the first ground portion 110, the second ground portion 120, and the second radiating portion 142 in FIG. 1 may be, for example, an L shape, but it is not intended to limit the present invention. In addition, as shown in FIG. 1 , in an embodiment, the integrated antenna 100 further includes a substrate 160 , and the first ground portion 110 , the second ground portion 120 , the extended ground portion 130 , and the radiating unit 140 are all disposed on the substrate 160 . On a surface 161. In other words, the integrated antenna 100 can be equivalent to a planar antenna.
綜上所述，本發明的第一接地部與第二接地部是從一接地面延伸而出，且延伸接地部是從第一接地部延伸而出。此外，本發明更利用輻射單元激發第一接地部、第二接地部與延伸接地部。藉此，延伸接地部與第一接地部將可共用同一接地點，進而有助於縮減整合式天線的硬體空間。再者，第一接地部還可用以作為第二接地部與延伸接地部之間的隔離元件，進而有助於增加整合式天線的通訊品質。 In summary, the first ground portion and the second ground portion of the present invention extend from a ground plane, and the extended ground portion extends from the first ground portion. In addition, the present invention further utilizes the radiating element to excite the first ground portion, the second ground portion, and the extended ground portion. Thereby, the extended grounding portion and the first grounding portion can share the same grounding point, thereby helping to reduce the hardware space of the integrated antenna. Furthermore, the first ground portion can also be used as an isolation component between the second ground portion and the extended ground portion, thereby contributing to increase the communication quality of the integrated antenna.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明的精神和範圍內，當可作些許的更動與潤飾，故本發明的保護範圍當視後附的申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
