Abstract
Description
本發明係與天線結構有關，特別是指一種藉由金屬殼體作為天線輻射體的天線結構。 The invention relates to an antenna structure, and in particular to an antenna structure by means of a metal casing as an antenna radiator.
隨著消費市場對於電子產品的質感要求，金屬外殼已成為高質感的象徵。但具有通訊功能的電子產品(例如手機、筆記型電腦、平板電腦、螢幕及主機整合於一體的電腦等)在使用金屬外殼時，往往天線的設計僅能遠離該金屬外殼，以避免影響天線的功能，也就是說，電子產品的外殼不是全部選用金屬。 With the consumer market demand for electronic products, the metal casing has become a symbol of high quality. However, electronic products with communication functions (such as mobile phones, notebook computers, tablets, screens, and computers integrated with the mainframe) often use antennas that are designed to be remote from the metal casing to avoid affecting the antenna. The function, that is to say, the outer casing of the electronic product is not all metal.
台灣新型第M403115號專利係揭露一種寬頻天線模組與整合寬頻天線模組之機殼結構，來解決前述的問題。該新型專利主要係將電路基板與金屬機殼連接，且金屬機殼的外殼槽孔正對電路基板的槽孔天線，更精確來說，外殼槽孔需正對該電路基板的槽孔天線的槽孔，且金屬機殼的外殼槽孔的形狀與大小需與槽孔天線的槽孔完全相同，如此，寬頻天線才能被操作在預定的頻帶上，且該槽孔的位置係固定的，而不能被調整。但因為外殼槽孔與槽孔天線的槽孔需相互配合，因此，當金屬機殼的外殼槽孔尺寸固定了，該寬頻天線的操作頻率就固定了，而無法任意調整操作頻率。 Taiwan's new M403115 patent discloses a wideband antenna module and a chassis structure for integrating a wideband antenna module to solve the aforementioned problems. The new patent mainly connects the circuit substrate with the metal casing, and the slot of the metal casing is opposite to the slot antenna of the circuit substrate. More precisely, the slot of the casing needs to be positively oriented to the slot antenna of the circuit substrate. Slot, and the shape and size of the slot of the metal casing must be exactly the same as the slot of the slot antenna, so that the broadband antenna can be operated in a predetermined frequency band, and the position of the slot is fixed, and Cannot be adjusted. However, since the slot of the outer casing and the slot of the slot antenna need to cooperate with each other, when the slot size of the outer casing of the metal casing is fixed, the operating frequency of the broadband antenna is fixed, and the operating frequency cannot be arbitrarily adjusted.
為了改善先前技術中所述的問題，本發明係提供一種能任意調整操作頻率的天線結構，來解決先前技術中所述的問題。且本發明的天線結構係較先前技術更易於組裝。 In order to improve the problems described in the prior art, the present invention provides an antenna structure capable of arbitrarily adjusting an operating frequency to solve the problems described in the prior art.

如第1及2圖所示，本發明的天線結構10係被應用於無線通訊裝置，以供無線通訊裝置傳送及接收訊號。無線通訊裝置可以是筆記型電腦、平板電腦、手機、數位相機等裝置。於此實施例中，本發明係以一筆記型電腦的外殼為例來作說明，該天線結構10包括一殼體11、一第一 導電單元12、一第二導電單元13、一第三導電單元14、一第四導電單元15、一第一電路板16、一第二電路板17、一第一接地片18及一第二接地片19。 As shown in Figures 1 and 2, the antenna structure 10 of the present invention is applied to a wireless communication device for transmitting and receiving signals by a wireless communication device.

該殼體11係具有一槽縫(slot)111、一第一金屬殼112及一第 二金屬殼113。該槽縫111係貫穿該殼體11，且位在該第一金屬殼112及該第二金屬殼113之間。該槽縫111較佳係以切割方式形成，但不以切割方式為限。需要注意的是，於此實施例中，該槽縫111的兩終端115、116係分別位在該殼體11的兩相對側邊117、118，表示，該殼體11係被切割成兩塊，而這兩塊分別是該第一金屬殼112及該第二金屬殼113。 The housing 11 has a slot 111, a first metal shell 112 and a first Two metal shells 113. The slot 111 extends through the housing 11 and is located between the first metal shell 112 and the second metal shell 113. The slit 111 is preferably formed by cutting, but is not limited by the cutting method. It should be noted that, in this embodiment, the two terminals 115, 116 of the slot 111 are respectively located at opposite sides 117, 118 of the housing 11, indicating that the housing 11 is cut into two pieces. And the two pieces are the first metal shell 112 and the second metal shell 113, respectively.
如第3圖所示，該圖係顯示槽縫111的終端115的放大圖， 圖中可清楚看出，槽縫111係可定義兩相面對的側表面111a、111b。由於槽縫111的終端116與本圖結構相同，因此不再贅述。 As shown in FIG. 3, this figure shows an enlarged view of the terminal 115 of the slot 111. As is clear from the figure, the slit 111 can define two side facing side surfaces 111a, 111b. Since the terminal 116 of the slot 111 is the same as the structure of the figure, it will not be described again.
但在實務中，該槽縫111的兩終端115、116也可以不延伸 至該殼體11的相對側邊117、118，例如，僅在殼體11的中間切割出適當的長度，或從殼體11的側邊117、118往中間切割等，故該槽縫111的兩終端115、116係不以延伸至該殼體11的相對側邊為限117、118。 However, in practice, the two terminals 115, 116 of the slot 111 may not extend. To the opposite side edges 117, 118 of the housing 11, for example, only the appropriate length is cut in the middle of the housing 11, or cut from the side edges 117, 118 of the housing 11, etc., so that the slot 111 The two terminals 115, 116 are not limited to 117, 118 extending to opposite sides of the housing 11.
該些導電單元12-15係分別連接該殼體11的第一金屬殼112 及該第二金屬殼113，且蓋在該槽縫111上，並間隔並排。該些導電單元12-15係作為輻射訊號在第一金屬殼112及第二金屬殼113傳輸的路徑，完整的應用說明請容後在述。於此實施例中，該些導電單元12-15係以銅箔為例，但實際上，該些導電單元12-15也可以選用其他導電貼片；或者在切割殼體11的槽縫111時預先保留該些導電單元12-15位置的金屬結構，如此就不需要另貼銅箔，故，該些導電單元12-15的形成係不以本較佳實施例所述銅箔為限。 The conductive units 12-15 are respectively connected to the first metal shell 112 of the housing 11. And the second metal shell 113 is covered on the slot 111 and spaced side by side. The conductive units 12-15 are used as the paths for the radiation signals to be transmitted in the first metal shell 112 and the second metal shell 113. The complete application description will be described later. In this embodiment, the conductive units 12-15 are exemplified by copper foils, but in practice, the conductive units 12-15 may also be other conductive patches; or when the slots 111 of the housing 11 are cut. The metal structures at the positions of the conductive units 12-15 are reserved in advance, so that the copper foil is not required to be attached. Therefore, the formation of the conductive units 12-15 is not limited to the copper foil described in the preferred embodiment.

A process of (nano molding technology) is formed in the slot 111 to fixedly connect the first metal shell 112 and the second metal shell 113. Thus, the casing 11 is an integral structure, not separated. structure. However, if the housing 11 is cutting the slot 111 has been retained The conductive units 12-15 indicate that the conductive units 12-15 are part of the housing 11, and the housing 11 is not cut. Therefore, the combining unit 114 can also be omitted, so the housing 11 can be omitted. It is not limited to having the combining unit 114.
再者，若該殼體11係由該第一金屬殼112、該第二金屬殼 113及結合單元114連接成一體時，該槽縫111係不存在，故該槽縫111也可以被省略。 Furthermore, if the housing 11 is composed of the first metal shell 112 and the second metal shell When the 113 and the joining unit 114 are integrally connected, the slit 111 does not exist, so the slit 111 can also be omitted.

The straight sections 164, 166, 174, and 176 of the first microstrip line 163 and the second microstrip line 173 respectively span the slot 111, and the conductive units 12-15 are respectively connected to the first metal shell 111 and the The second metal shell 113, therefore, the radiation signals of the first and second microstrip lines 163, 173 can be coupled to the first metal shell 112 and the second metal shell 113 of the housing 11, and the radiation signal system Flowing around the slot 111, and forming a radiation signal loop by the first metal shell 112, the second metal shell 113, and the conductive units 12-15, so that the housing 11 and the combination of the conductive units 12-15 The electromagnetic wave is radiated by the radiator as an antenna.
其中，該兩微帶線16、17的直段164、166、174、176及該 些導電單元12-15的配置係用以決定該天線結構的操作頻率，於本實施例中，每一微帶線16、17具有兩直段164、166、174、176，且鄰近每一微帶線16、17有兩導電單元164、174連接該殼體11的第一金屬殼112及該第二金屬殼113上，如此，該天線結構係可被操作在兩個頻率(例如2.4GHz及5GHz)上。然而，若該天線結構僅需操作在一個操作頻率時，則微帶線僅需設計一直段及一導電單元。因此，該導電單元及該微帶線的直段數量係可依操作頻率來增加或減少，故不以一個或兩個為限。再者，若要改變本發明的天線結構的操作頻率及匹配阻抗只要調整該導電單元的位置，就可獲得不同操作頻率及匹配阻抗的需求。雖然於本實施例中，該些導電單元12-15的部分(虛線部分)分別位在該兩電路板16-17與該殼體11之間，若改變本發明的天線結構的操作頻率及匹配阻抗些時，該些導電單元12-15也可能不在該兩電路板16-17與該殼體11之間，故，導電單元係不以在電路板及該殼體之間為限。 Wherein the straight segments 164, 166, 174, 176 of the two microstrip lines 16, 17 and the The arrangement of the conductive units 12-15 is used to determine the operating frequency of the antenna structure. In this embodiment, each microstrip line 16, 17 has two straight segments 164, 166, 174, 176, and adjacent to each micro The strips 16, 17 have two conductive units 164, 174 connected to the first metal shell 112 and the second metal shell 113 of the housing 11, such that the antenna structure can be operated at two frequencies (for example, 2.4 GHz and 5GHz). However, if the antenna structure only needs to be operated at an operating frequency, the microstrip line only needs to design a straight section and a conductive unit. Therefore, the number of straight sections of the conductive unit and the microstrip line can be increased or decreased according to the operating frequency, and thus is not limited to one or two. Furthermore, if the operating frequency and matching impedance of the antenna structure of the present invention are to be changed, as long as the position of the conductive unit is adjusted, the requirements of different operating frequencies and matching impedances can be obtained. In this embodiment, the portions (dotted lines) of the conductive units 12-15 are respectively located between the two circuit boards 16-17 and the housing 11, and if the operating frequency and matching of the antenna structure of the present invention are changed, When the impedance is small, the conductive units 12-15 may not be between the two circuit boards 16-17 and the housing 11. Therefore, the conductive unit is not limited between the circuit board and the housing.
此外，該第二電路板17、該第三導電單元14、第四導電單 元15及該第二接地片19也可以被省略，因此，該天線結構係不以本較佳實施例所繪為限。 In addition, the second circuit board 17, the third conductive unit 14, and the fourth conductive single The element 15 and the second grounding piece 19 may also be omitted. Therefore, the antenna structure is not limited to the preferred embodiment.
該些電路板16、17及該些導電單元12-15係可沿該槽縫111 來任意配置，以增加組裝彈性。再者，由於本發明的天線結構的電路板上16、17不需要有與該槽縫111對應的孔，因此，在組裝上，本發明的天線結構係較先前技術更容易。 The circuit boards 16, 17 and the conductive units 12-15 are along the slot 111 Arbitrarily configured to increase assembly flexibility. Moreover, since the circuit boards 16, 17 of the antenna structure of the present invention do not need to have holes corresponding to the slots 111, the antenna structure of the present invention is easier to assemble than the prior art.
於此實施例中，該第一金屬殼112的面積係小於該第二金屬 殼113，表示，該天線結構的輻射位置通常是在殼體11的周圍。該第一金屬殼112的面積也可以等於該第二金屬殼113，故不以該第一金屬殼112的面積小於該第二金屬殼113的面積為限。 In this embodiment, the area of the first metal shell 112 is smaller than the second metal. The housing 113 indicates that the radiating position of the antenna structure is generally around the housing 11. The area of the first metal shell 112 may also be equal to the second metal shell 113, so the area of the first metal shell 112 is not limited to the area of the second metal shell 113.
由於第4及5圖係相同的結構，且在實際天線特性測試中可 獲得相近的特性圖，因此，僅顯示其中一天線實際測試圖。如第6圖所示，該圖顯示本發明的天線結構在2：1電壓駐波比(Voltage Standing Wave Ratio,VSWR)的定義下經實際測試後產生的兩操作頻率(即2.4GHz及5GHz)，以顯 示本發明的天線結構確實可實現其操作頻率。 Because the 4th and 5th drawings are the same structure, and can be tested in the actual antenna characteristics. A similar characteristic map is obtained, so only one of the antenna actual test patterns is displayed. As shown in FIG. 6, the figure shows the two operating frequencies (ie, 2.4 GHz and 5 GHz) generated by the antenna structure of the present invention after actual testing under the definition of a 2:1 Voltage Standing Wave Ratio (VSWR). To show It is shown that the antenna structure of the present invention does achieve its operating frequency.
