本發明係關於一種包括LC諧振器之天線。The present invention relates to an antenna including an LC resonator.

專利文獻1係開示有包括LC諧振器之天線。如圖16所示,專利文獻1之天線90係具有電介質層910、導體層920、及供電線930。電介質層910係具有一對主面。導體層920係被形成於電介質層910的主面的一邊。供電線930係被形成於電介質層910的主面之剩下之一邊。導體層920係被形成為C字形。又,導體層920的兩端部係彼此遠離以相向。導體層920的兩端部係形成電容器940。導體層920與供電線930,係使用貫穿電介質層910之電鍍通過孔950,以彼此連接。詳細說來,電鍍通過孔950係使供電線930的端部,連接於導體層920的一部份,且位於兩端部的一者附近之一部份。 [專利文獻]Patent Document 1 discloses an antenna including an LC resonator.

[專利文獻1]日本特開2016-225956號公報[Patent Document 1] JP 2016-225956 A

當使專利文獻1之天線90以高頻率使用時,在相對介電常數較高之電介質層910所產生之傳送損失係增大。因此,專利文獻1之天線90係在高頻率中,有無法獲得較高放射效率之問題。When the antenna 90 of Patent Document 1 is used at a high frequency, the transmission loss generated in the dielectric layer 910 having a relatively high relative permittivity increases. Therefore, the antenna 90 of Patent Document 1 is at a high frequency, and there is a problem that a higher radiation efficiency cannot be obtained.

在此,本發明之目的,係在於提供一種在高頻率中,可獲得較高放射效率之天線。Here, the object of the present invention is to provide an antenna that can achieve higher radiation efficiency at high frequencies.

本發明之一側面,係提供一種包括第1端子、第2端子、LC諧振器、接地平面、及基板之天線。該LC諧振器係被連接於該第1端子。該LC諧振器係具有主部與相向部。該主部係具有具備缺口之環狀形狀。該主部係具有第1端部與第2端部。該第1端部與該第2端部,係位於彼此遠離之位置,以形成該缺口。該相向部係具有第1相向部與第2相向部。該第1相向部係具有第1主相向部與第1被連接部。該第1被連接部係被連接於該第1端部。該第2相向部係被連接於該第2端部。該第2相向部係具有第2主相向部。該接地平面係分別被連接於該第2端子及該LC諧振器。該接地平面、該主部、及該第1相向部的全部,係被形成於該基板上。該第2相向部之構造,係與該基板為不同個體。在與該基板直交之直交方向中,該第1主相向部與該第2主相向部,係彼此遠離以相向。 [發明效果]One aspect of the present invention is to provide an antenna including a first terminal, a second terminal, an LC resonator, a ground plane, and a substrate. The LC resonator is connected to the first terminal. This LC resonator has a main part and an opposing part. The main part has a ring shape with notches. The main part has a first end and a second end. The first end and the second end are located far away from each other to form the gap. The facing portion has a first facing portion and a second facing portion. The first facing portion has a first main facing portion and a first connected portion. The first connected portion is connected to the first end. The second facing portion is connected to the second end. The second facing portion has a second main facing portion. The ground plane is connected to the second terminal and the LC resonator, respectively. All of the ground plane, the main part, and the first facing part are formed on the substrate. The structure of the second facing portion is different from that of the substrate. In the orthogonal direction orthogonal to the substrate, the first main facing portion and the second main facing portion are spaced apart from each other to face each other. [Invention Effect]

本發明之天線之構造係如下所述:第2相向部之構造,係與基板為不同個體;又,在與基板直交之直交方向中,第1主相向部與第2主相向部,係彼此遠離以相向。藉此,構成電容器之第1主相向部與第2主相向部間之空間,係僅包含低相對介電常數之空氣層。藉此,本發明之天線即使在高頻率使用,其與如專利文獻1之天線90之天線相比較下,也可獲得較高之放射效率。The structure of the antenna of the present invention is as follows: the structure of the second facing portion is different from the substrate; and, in the orthogonal direction perpendicular to the substrate, the first main facing portion and the second main facing portion are each other Stay away to face each other. Thereby, the space between the first main facing portion and the second main facing portion constituting the capacitor only includes an air layer with a low relative permittivity. Thereby, even if the antenna of the present invention is used at a high frequency, it can obtain a higher radiation efficiency compared with an antenna such as the antenna 90 of Patent Document 1.

又,在本發明之天線中,接地平面、主部及第1相向部的全部,係被形成於基板上。藉此,本發明之天線,係在與使主部與基板為不同個體之構造之情形相比較下,可確保主部所負責之LC諧振器之電感成分較大。因此,本發明之天線,係不增大天線全體之尺寸地,可使天線之諧振頻率低頻化。又,所謂可確保LC諧振器之電感成分較大,係意味在具有一定之諧振頻率之天線中,可使天線之電容成分較小。亦即,本發明之天線,係在與使主部與基板為不同個體之構造之情形相比較下,不改變天線之諧振頻率地,可謀求天線之小型化。Furthermore, in the antenna of the present invention, all of the ground plane, the main portion, and the first facing portion are formed on the substrate. Thereby, the antenna of the present invention can ensure that the inductance component of the LC resonator that the main part is responsible for is larger when compared with the case where the main part and the substrate are of different individual structures. Therefore, the antenna of the present invention can reduce the resonant frequency of the antenna without increasing the size of the entire antenna. In addition, the so-called ensuring that the inductance component of the LC resonator is large means that the capacitance component of the antenna can be made small in an antenna with a certain resonant frequency. That is, the antenna of the present invention can achieve the miniaturization of the antenna without changing the resonant frequency of the antenna compared with the case where the main part and the substrate are of different individual structures.

如圖6所示,本實施形態之第1被連接部466,係被連接於第1端部414。第1被連接部466也被連接於訊號圖樣153。亦即,訊號圖樣153係透過第1被連接部466,以被連接於第1端部414。As shown in FIG. 6, the first connected portion 466 of this embodiment is connected to the first end 414.

由圖2及圖4可以理解到:第2相向部470之構造,係與基板150為不同個體。亦即,第2相向部470之構造,係與主部410及第1相向部460皆為不同個體。藉此,本實施形態之天線100,係藉變更第2相向部470,可調整天線100之諧振頻率。因此,本實施形態之天線100之設計自由度係變高。It can be understood from FIGS. 2 and 4 that the structure of the second facing portion 470 is different from that of the substrate 150. That is, the structure of the second facing portion 470 is different from the main portion 410 and the first facing portion 460. Therefore, the antenna 100 of the present embodiment can adjust the resonance frequency of the antenna 100 by changing the second facing portion 470. Therefore, the degree of freedom in design of the antenna 100 of the present embodiment is increased.

如圖9所示,本實施形態之第2相向部470,係具有第2主相向部472、第2被連接部476、及被固定部478。亦即,在第2相向部470設有第2被連接部476、及被固定部478。As shown in FIG. 9, the second facing portion 470 of this embodiment has a second main facing portion 472, a second connected portion 476, and a fixed portion 478. That is, the second facing portion 470 is provided with a second connected portion 476 and a fixed portion 478.

如圖9所示,本實施形態之第2主相向部472,係具有平板形狀。更詳細說來,第2主相向部472係具有與直交方向直交之平板形狀。由圖2及圖4可以理解到:第2主相向部472係在直交方向中,位於比主部410與第1相向部460還要靠近上方之位置。第2主相向部472係在直交方向中,位於遠離主部410與第1相向部460之位置。第2主相向部472係在直交方向中,位於第1主相向部462之上方。在與基板150直交之直交方向中,第1主相向部462與第2主相向部472係彼此遠離以相向。亦即,第1主相向部462與第2主相向部472,係透過空氣層,彼此遠離以相向。藉此,構成電容器之第1主相向部462與第2主相向部472間之空間,係成為低相對介電常數之空氣層。因此,本實施形態之天線100,即使在高頻率下使用,其與如專利文獻1之天線90之天線相比較下,也可獲得較高之放射效率。As shown in FIG. 9, the second main facing portion 472 of this embodiment has a flat plate shape. In more detail, the second main facing portion 472 has a flat plate shape orthogonal to the orthogonal direction. It can be understood from FIGS. 2 and 4 that the second main facing portion 472 is in the orthogonal direction, and is located above the main portion 410 and the first facing portion 460. The second main facing portion 472 is in the orthogonal direction and is located away from the main portion 410 and the first facing portion 460. The second main facing portion 472 is located above the first main facing portion 462 in the orthogonal direction. In the orthogonal direction perpendicular to the substrate 150, the first main facing portion 462 and the second main facing portion 472 are spaced apart from each other to face each other. That is, the first main facing portion 462 and the second main facing portion 472 pass through the air layer and are separated from each other to face each other. Thereby, the space between the first main facing portion 462 and the second main facing portion 472 constituting the capacitor becomes an air layer with a low relative permittivity. Therefore, even if the antenna 100 of this embodiment is used at a high frequency, it can obtain a higher radiation efficiency compared with an antenna such as the antenna 90 of Patent Document 1.

如圖4所示,在與直交方向直交之左右方向中,第2主相向部472係具有大於第1主相向部462之尺寸S1之尺寸S2。又,在與直交方向及左右方向兩者直交之前後方向中,第2主相向部472係具有大於第1主相向部462之尺寸S3之尺寸S4。如圖6所示,當使第2主相向部472的像,在直交方向上,投影於基板150上後,第1主相向部462係位於第2主相向部472的投影像P內。藉此,即使第2相向部470被固定於基板150,使得第1主相向部462與第2主相向部472,係在左右方向中,位於若干偏移之位置,也可以抑制天線100之電容成分之變化。同樣地,即使第2相向部470被固定於基板150,使得第1主相向部462與第2主相向部472,在前後方向中,位於若干偏移之位置,也可以抑制天線100之電容成分之變化。因此,可抑制天線100之天線特性之變化。As shown in FIG. 4, in the left-right direction orthogonal to the orthogonal direction, the second main facing portion 472 has a size S2 that is larger than the size S1 of the first main facing portion 462. In addition, in the front and rear directions orthogonal to both the orthogonal direction and the left-right direction, the second main facing portion 472 has a size S4 that is larger than the size S3 of the first main facing portion 462. As shown in FIG. 6, when the image of the second main facing portion 472 is projected on the substrate 150 in the orthogonal direction, the first main facing portion 462 is located in the projected image P of the second main facing portion 472. Thereby, even if the second facing portion 470 is fixed to the substrate 150, so that the first main facing portion 462 and the second main facing portion 472 are located at slightly offset positions in the left-right direction, the capacitance of the antenna 100 can be suppressed. Changes in composition. Similarly, even if the second facing portion 470 is fixed to the substrate 150 so that the first main facing portion 462 and the second main facing portion 472 are located at a slightly offset position in the front-rear direction, the capacitance component of the antenna 100 can be suppressed The change. Therefore, the variation of the antenna characteristics of the antenna 100 can be suppressed.

而且,本發明並不侷限於此。也可以變更天線100,使得在與直交方向直交之左右方向中,第1主相向部462之尺寸S1,變得大於第2主相向部472之尺寸S2。在此情形下,即使第2相向部470係被固定於基板150,使得第1主相向部462與第2主相向部472在左右方向中,位於若干偏移之位置,也可以抑制被變更後之天線100之電容成分之變化。因此,可抑制被變更後之天線100之天線特性之變化。Moreover, the present invention is not limited to this. The antenna 100 may be changed so that the size S1 of the first main facing portion 462 is larger than the size S2 of the second main facing portion 472 in the left-right direction perpendicular to the orthogonal direction. In this case, even if the second facing portion 470 is fixed to the substrate 150 so that the first main facing portion 462 and the second main facing portion 472 are located slightly offset in the left-right direction, it can be suppressed from being changed. The change of the capacitance component of the antenna 100. Therefore, the change of the antenna characteristics of the antenna 100 after the modification can be suppressed.

參照圖11,第2相向部470A之構造,係與基板150A為不同個體。亦即,第2相向部470A之構造,係與主部410及第1相向部460A皆為不同個體。藉此,本實施形態之天線100A係藉變更第2相向部470A,可調整天線100A之諧振頻率。因此,天線100A之設計自由度係變高。11, the structure of the second facing portion 470A is different from that of the substrate 150A. That is, the structure of the second facing portion 470A is different from the main portion 410 and the first facing portion 460A. Thereby, the antenna 100A of this embodiment can adjust the resonance frequency of the antenna 100A by changing the second facing portion 470A. Therefore, the design freedom of the antenna 100A is increased.

參照圖2及圖11,本實施形態之第2相向部470A之構造,係使第1實施形態之天線100的第2相向部470,在左右方向中,兩個並列。2 and 11, the structure of the second facing portion 470A of the present embodiment is such that two second facing portions 470 of the antenna 100 of the first embodiment are arranged side by side in the left-right direction.

如上所述,本實施形態之天線100A係構成如下:第1主相向部462A係在左右方向中,尺寸大於第1實施形態之第1主相向部462;第2相向部470A係使第1實施形態之第2相向部470,在左右方向中,兩個並列。藉此,本實施形態之天線100A的LC諧振器400A,係在與第1實施形態之天線100的LC諧振器400相比較下,變得可設定諧振頻率較低。而且,本發明並不侷限於此。第2相向部470A係也可以使第1實施形態之第2相向部470,在左右方向中,三個以上並列。As described above, the antenna 100A of this embodiment is configured as follows: the first main facing portion 462A is in the left-right direction, and the size is larger than the first main facing portion 462 of the first embodiment; the second facing portion 470A is the first embodiment In the second facing portion 470 of the form, two are juxtaposed in the left-right direction. As a result, the LC resonator 400A of the antenna 100A of the present embodiment can be set to have a lower resonance frequency compared with the LC resonator 400 of the antenna 100 of the first embodiment. Moreover, the present invention is not limited to this. The second facing portion 470A may have three or more second facing portions 470 of the first embodiment arranged side by side in the left-right direction.

如圖11所示,本實施形態之第2相向部470A係具有第2主相向部472A、第2被連接部476A、及被固定部478A。亦即,在第2相向部470A係設有第2被連接部476A與被固定部478A。As shown in FIG. 11, the second facing portion 470A of the present embodiment has a second main facing portion 472A, a second connected portion 476A, and a fixed portion 478A. That is, the second facing portion 470A is provided with a second connected portion 476A and a fixed portion 478A.

如圖11所示,本實施形態之第2主相向部472A,係具有平板形狀。更詳細說來,第2主相向部472A係具有與直交方向直交之平板形狀。第2主相向部472A係在直交方向中,位於比主部410與第1相向部460A之任一者還要靠近上方。第2主相向部472A係在直交方向中,位於自主部410及第1相向部460A之任一者遠離之位置。第2主相向部472A係在直交方向中,位於第1主相向部462A的上方。在與基板150A直交之直交方向中,第1主相向部462A與第2主相向部472A,係彼此遠離以相向。亦即,第1主相向部462A與第2主相向部472A,係透過空氣層,彼此遠離以相向。藉此,構成電容器之第1主相向部462A與第2主相向部472A間之空間,係成為低相對介電常數之空氣層。因此,本實施形態之天線100A係即使在高頻率下使用,其在與如專利文獻1之天線90之天線相比較下,也可獲得較高之放射效率。As shown in FIG. 11, the second main facing portion 472A of this embodiment has a flat plate shape. In more detail, the second main facing portion 472A has a flat plate shape orthogonal to the orthogonal direction. The second main facing portion 472A is in the orthogonal direction, and is located above any one of the main portion 410 and the first facing portion 460A. The second main facing portion 472A is in the orthogonal direction, and is located at a position away from any one of the main portion 410 and the first facing portion 460A. The second main facing portion 472A is located in the orthogonal direction above the first main facing portion 462A. In the orthogonal direction orthogonal to the substrate 150A, the first main facing portion 462A and the second main facing portion 472A are spaced apart from each other to face each other. That is, the first main opposing portion 462A and the second main opposing portion 472A pass through the air layer and are separated from each other to face each other. Thereby, the space between the first main facing portion 462A and the second main facing portion 472A constituting the capacitor becomes an air layer with a low relative permittivity. Therefore, even if the antenna 100A of the present embodiment is used at a high frequency, it can obtain a higher radiation efficiency compared with an antenna such as the antenna 90 of Patent Document 1.

參照圖11,在與直交方向直交之左右方向中,第2主相向部472A之尺寸,係大於第1主相向部462A之尺寸。又,在與直交方向及左右方向兩者直交之前後方向中,第2主相向部472A之尺寸係大於第1主相向部462A之尺寸。當使第2主相向部472A的像,在直交方向上,投影到基板150A上後,第1主相向部462A係位於第2主相向部472A的投影像內。藉此,即使第2相向部470A被固定於基板150A,使得第1主相向部462A與第2主相向部472A係在左右方向中,位於若干偏移之位置,也可抑制天線100A的電容成分之變化。同樣地,即使第2相向部470A係被固定於基板150A,使得第1主相向部462A與第2主相向部47216A係在前後方向中,位於若干偏移之位置,也可抑制天線100A的電容成分之變化。因此,可抑制天線100A之天線特性之變化。11, in the left-right direction perpendicular to the orthogonal direction, the size of the second main facing portion 472A is larger than the size of the first main facing portion 462A. In addition, in the front-to-back direction orthogonal to both the orthogonal direction and the left-right direction, the size of the second main facing portion 472A is larger than the size of the first main facing portion 462A. When the image of the second main facing portion 472A is projected on the substrate 150A in the orthogonal direction, the first main facing portion 462A is located in the projected image of the second main facing portion 472A. Thereby, even if the second facing portion 470A is fixed to the substrate 150A so that the first main facing portion 462A and the second main facing portion 472A are located at slightly offset positions in the left-right direction, the capacitance component of the antenna 100A can be suppressed The change. Similarly, even if the second facing portion 470A is fixed to the substrate 150A so that the first main facing portion 462A and the second main facing portion 47216A are located at a slightly offset position in the front-rear direction, the capacitance of the antenna 100A can be suppressed. Changes in composition. Therefore, the change in the antenna characteristics of the antenna 100A can be suppressed.

而且,本發明並不侷限於此。也可以變更天線100A,使得在與直交方向直交之左右方向中,第1主相向部462A之尺寸變得大於第2主相向部472A之尺寸。在此情形下,即使第2相向部470A被固定於基板150A,使得第1主相向部462A與第2主相向部472A係在左右方向中,位於若干偏移之位置,也可以抑制被變更後之天線100A的電容成分之變化。因此,可抑制被變更後之天線100A之天線特性之變化。Moreover, the present invention is not limited to this. The antenna 100A may be changed so that the size of the first main facing portion 462A is larger than the size of the second main facing portion 472A in the left-right direction orthogonal to the orthogonal direction. In this case, even if the second facing portion 470A is fixed to the substrate 150A so that the first main facing portion 462A and the second main facing portion 472A are located at slightly offset positions in the left-right direction, it can be suppressed from being changed. The change of the capacitance component of the antenna 100A. Therefore, the change of the antenna characteristics of the antenna 100A after the modification can be suppressed.

Referring to FIG. 13, the first connected portion 466B is also connected to the signal pattern 153. That is, the signal pattern 153 is connected to the first end 414B through the first connected portion 466B.

參照圖13,本實施形態之第2相向部470B係金屬製。第2相向部470B係被連接於第2端部416B。參照圖2及圖13,第2相向部470B係使第1實施形態之第2相向部470,相對於在直交方向上延伸之軸而言,成為旋轉90°後之配置。Referring to Fig. 13, the second opposing portion 470B of this embodiment is made of metal. The second facing portion 470B is connected to the second end 416B. 2 and FIG. 13, the second facing portion 470B is configured such that the second facing portion 470 of the first embodiment is rotated by 90° with respect to the axis extending in the orthogonal direction.

參照圖13,第2相向部470B之構造,係與基板150B為不同個體。亦即,第2相向部470B之構造,係與主部410B及第1相向部460B皆為不同個體。藉此,本實施形態之天線100B,係藉變更第2相向部470B,可調整天線100B之諧振頻率。因此,天線100B之設計自由度係變高。Referring to FIG. 13, the structure of the second facing portion 470B is different from that of the substrate 150B. That is, the structure of the second facing portion 470B is different from the main portion 410B and the first facing portion 460B. Therefore, the antenna 100B of this embodiment can adjust the resonance frequency of the antenna 100B by changing the second facing portion 470B. Therefore, the design freedom of the antenna 100B is increased.

如圖15所示,本實施形態之第2相向部470B係具有第2主相向部472B、孔474、第2被連接部476B、及被固定部478B。亦即,在第2相向部470B係設有第2被連接部476B與被固定部478B。As shown in FIG. 15, the second facing portion 470B of the present embodiment has a second main facing portion 472B, a hole 474, a second connected portion 476B, and a fixed portion 478B. That is, the second facing portion 470B is provided with a second connected portion 476B and a fixed portion 478B.

如圖15所示,本實施形態之第2主相向部472B係具有平板形狀。更詳細說來,第2主相向部472B係具有與直交方向直交之平板形狀。參照圖13,第2主相向部472B係在直交方向中,位於比主部410B與第1相向部460B還要靠近上方。第2主相向部472B係在直交方向中,位於自主部410B與第1相向部460B遠離之位置。第2主相向部472B係在直交方向中,位於第1主相向部462B之上方。在與基板150B直交之直交方向中,第1主相向部462B與第2主相向部472B,係彼此遠離以相向。亦即,第1主相向部462B與第2主相向部472B,係透過空氣層,彼此遠離以相向。藉此,構成電容器之第1主相向部462B與第2主相向部472B間之空間,係成為低相對介電常數之空氣層。因此,本實施形態之天線100B,即使在高頻率下使用,其在與如專利文獻1之天線90之天線相比較下,也可獲得較高之放射效率。As shown in FIG. 15, the 2nd main opposing part 472B of this embodiment has a flat plate shape. In more detail, the second main facing portion 472B has a flat plate shape orthogonal to the orthogonal direction. Referring to FIG. 13, the second main facing portion 472B is in the orthogonal direction, and is located higher than the main portion 410B and the first facing portion 460B. The second main facing portion 472B is in the orthogonal direction, and is located at a position away from the main portion 410B and the first facing portion 460B. The second main facing portion 472B is located above the first main facing portion 462B in the orthogonal direction. In the orthogonal direction orthogonal to the substrate 150B, the first main facing portion 462B and the second main facing portion 472B are separated from each other to face each other. That is, the first main facing portion 462B and the second main facing portion 472B penetrate the air layer and are separated from each other to face each other. Thereby, the space between the first main facing portion 462B and the second main facing portion 472B constituting the capacitor becomes an air layer with a low relative permittivity. Therefore, even if the antenna 100B of this embodiment is used at a high frequency, it can obtain a higher radiation efficiency compared with an antenna such as the antenna 90 of Patent Document 1.

參照圖13,在與直交方向直交之左右方向中,第2主相向部472B之尺寸,係大於第1主相向部462B之尺寸。又,在與直交方向及左右方向兩者直交之前後方向中,第2主相向部472B之尺寸係大於第1主相向部462B之尺寸。當使第2主相向部472B的像,在直交方向上,投影到基板150B上後,第1主相向部462B係位於第2主相向部472B的投影像內。藉此,即使第2相向部470B係被固定於基板150B,使得第1主相向部462B與第2主相向部472B係在左右方向中,位於若干偏移之位置,天線100B的電容成分之變化係也被抑制。同樣地,即使第2相向部470B係被固定於基板150B,使得第1主相向部462B與第2主相向部472B係在前後方向中,位於若干偏移之位置,天線100B的電容成分之變化係也被抑制。因此,可抑制天線100B之天線特性之變化。13, in the left-right direction perpendicular to the orthogonal direction, the size of the second main facing portion 472B is larger than the size of the first main facing portion 462B. In addition, in the front and rear directions orthogonal to both the orthogonal direction and the left-right direction, the size of the second main facing portion 472B is larger than the size of the first main facing portion 462B. When the image of the second main facing portion 472B is projected on the substrate 150B in the orthogonal direction, the first main facing portion 462B is located in the projected image of the second main facing portion 472B. As a result, even if the second facing portion 470B is fixed to the substrate 150B, so that the first main facing portion 462B and the second main facing portion 472B are located at slightly offset positions in the left-right direction, the capacitance component of the antenna 100B changes Department is also suppressed. Similarly, even if the second facing portion 470B is fixed to the substrate 150B so that the first main facing portion 462B and the second main facing portion 472B are located at a slightly offset position in the front-rear direction, the capacitance component of the antenna 100B changes Department is also suppressed. Therefore, the change in the antenna characteristics of the antenna 100B can be suppressed.

而且,本發明並不侷限於此。也可以變更天線100B,使得在與直交方向及左右方向兩者直交之前後方向中,第1主相向部462B之尺寸,係大於第2主相向部472B之尺寸。在此情形下,即使第2相向部470B被固定於基板150B,使得第1主相向部462B與第2主相向部472B係在前後方向中,位於若干偏移之位置,被變更後之天線100B的電容成分之變化也被抑制。因此,可抑制被變更後之天線100B之天線特性之變化。Moreover, the present invention is not limited to this. The antenna 100B may be changed so that the size of the first main facing portion 462B is larger than the size of the second main facing portion 472B in the front and back directions orthogonal to both the orthogonal direction and the left-right direction. In this case, even if the second facing portion 470B is fixed to the substrate 150B, so that the first main facing portion 462B and the second main facing portion 472B are in the front-rear direction and are located at slightly offset positions, the modified antenna 100B The change of the capacitance component is also suppressed. Therefore, the change in the antenna characteristics of the antenna 100B after the modification can be suppressed.

如圖15所示,本實施形態之孔474,係在直交方向上貫穿第2主相向部472B。孔474係位於第2主相向部472B之前後方向中之中央附近。孔474係位於第2主相向部472B之左右方向中之中央附近。如此一來,本實施形態之第2相向部470B係具有孔474,所以,在本實施形態之天線100B中,係調整孔474之大小,藉此,變得可調整圖13所示之LC諧振器400B之電容容量。As shown in FIG. 15, the hole 474 of this embodiment penetrates the 2nd main opposing part 472B in the orthogonal direction. The hole 474 is located near the center in the front and rear direction of the second main facing portion 472B. The hole 474 is located near the center of the second main facing portion 472B in the left-right direction. In this way, the second opposing portion 470B of this embodiment has a hole 474. Therefore, in the antenna 100B of this embodiment, the size of the hole 474 is adjusted, whereby the LC resonance shown in FIG. 13 can be adjusted. The capacitance of the device 400B.
