[0033] Referring to FIG. 4, the pressing portion 212 presses the conductive film 500 against the portion 252 to be pressed, whereby the conductive film 500 and the portion 252 to be pressed are electrically connected. More specifically, the upper side surface 2122 of the pressing portion 212 presses the conductive film 500 against the upper portion 2522 to be pressed of the corresponding portion 252 to be pressed along the vertical direction, and the lower side surface 2122 of the pressing portion 212 presses the conductive film 500 against the lower portion 2524 to be pressed of the corresponding portion 252 to be pressed along the vertical direction, whereby the conductive film 500 and the corresponding portion 252 to be pressed are electrically connected.

[0034] In the antenna assembly 100 of the present embodiment, there are two combinations of the pressing portion 212 and the portion 252 to be pressed, and each of the two combinations electrically connects the antenna body 200 and the conductive film 500. Accordingly, in the antenna assembly 100 of the present embodiment, compared with the configuration in which the electrical connection between the antenna body 200 and the conductive film 500 is realized by only one of the above combinations, the electrical connection between the antenna body 200 and the conductive film 500 is surely achieved.

[0035] Referring to FIG. 4, the pressing portion 212 is partially received in the receiving hole 250 with a part of the conductive film 500 interposed between the pressing portion 212 and the portion 252 to be pressed, whereby the conductive film 500 is pressed against the portion 252 to be pressed. More specifically, each of the pressing portions 212 is partially received in the corresponding receiving hole 250 with a part of the conductive film 500 interposed between the pressing portion 212 and the corresponding portion 252 to be pressed in the vertical direction, whereby the conductive film 500 is pressed against the corresponding portion 252 to be pressed along the vertical direction.

[0036] As shown in FIG. 9, the conductive film 500 of the present embodiment is a flat conductor. More specifically, the conductive film 500 is a copper tape or a copper foil. The conductive film 500 is connected to a metal housing or the like (not shown) on which the antenna assembly 100 is mounted. Two cuts 510 are formed in the conductive film 500. The cuts 510 respectively correspond to the receiving holes 250, the arm portions 210, and the pressing portions 212. Note that the present invention is not limited to this, and the conductive film 500 may not have the cuts 510.

[0037] (Fixing operation of the conductive film to the antenna body)

[0038] The fixing operation of the conductive film 500 to the antenna body 200 will be described in detail below.

[0039] First, referring to FIGS. 7 to 9, the antenna member 150 and the conductive film 500 are prepared. Here, in the antenna member 150 before the conductive film 500 is fixed, the pressing portion 212 is located in front of the receiving hole 250 in the front-rear direction, and a space 220 exists between the first side portion 204 and the pressing portion 212.

[0040] Next, referring to FIGS. 6 and 9, the conductive film 500 is bent so that a part of the conductive film 500 extends upward. At this time, each of the cuts 510 is located on the above-mentioned part of the conductive film 500. Then, referring to FIGS. 6 and 8, the conductive film 500 is disposed below the antenna member 150 so that the above-mentioned part of the conductive film 500 is located directly below the space 220. As a result, the antenna assembly 100 is in the state shown in FIG. 6.

[0041] Thereafter, the conductive film 500 is moved upward with respect to the antenna member 150. As a result, the antenna assembly 100 is in the state shown in FIG. 5. At this time, the cut 510 (see FIG. 9) of the conductive film 500 is located between the pressing portion 212 and the receiving hole 250 (see FIG. 6).

[0042] In the state of FIG. 5, the arm portion 210 is pushed backward to move the pressing portion 212 backward. As a result, a part of the conductive film 500 is pushed into the receiving hole 250, and the antenna assembly 100 assumes the state from FIG. 2 to FIG. 4. In this state, the pressing portion 212 presses the conductive film 500 against the portion to be pressed 252, whereby the conductive film 500 and the portion to be pressed 252 are electrically connected. Thus, in the antenna assembly 100 of the present embodiment, a structure is provided that does not require soldering or the like to fix the conductive film 500 to the antenna body 200. That is, in the antenna assembly 100 of the present embodiment, workability in the operation of fixing the conductive film 500 to the antenna body 200 is improved.

[0043] Also, in the above state, the arm portion 210 is plastically deformed. As a result, the state in which the pressing portion 212 presses the conductive film 500 against the portion to be pressed 252 is maintained.

[0044] Furthermore, in the above state, the deformed portion 260 is elastically deformed more than the above pressing of the lower pressed portion 2524 of the portion to be pressed 252 of the conductive film 500. Also, the conductive film 500 is firmly sandwiched between the pressing portion 212 and the lower pressed portion 2524 of the portion to be pressed 252 by the reaction force of the elastic deformation of the deformed portion 260. Thereby, the contact between the conductive film 500 and the portion to be pressed 252 is strengthened.

[0045] Note that, as described above, each of the pressing portions 212 has a tapered shape. Thus, even if there are variations in the vertical size of the pressing portion 212 and the receiving hole 250, the pressing portion 212 can press the conductive film 500 against the portion to be pressed 252 at any location in the left-right direction of both side surfaces 2122. Therefore, stable contact between the conductive film 500 and the portion to be pressed 252 can be obtained.

[0046] (Second Embodiment) As shown in FIG. 10, the antenna assembly 100A of the second embodiment of the present invention includes an antenna member 150A made of a metal plate and a conductive film 500A. The antenna assembly 100A according to the present embodiment has the same configuration as the antenna assembly 100 (see FIG. 1) according to the above-described first embodiment. Therefore, among the components shown in FIGS. 10 to 21, the same reference numerals will be assigned to the components having the same configuration as those in the first embodiment. Also, the expressions for the orientation and direction in the present embodiment are the same as those in the first embodiment and will be used hereinafter.

Note that no hole corresponding to the receiving hole 250 of the first embodiment is formed in the first side portion 204A.

[0051] As shown in FIG. 15, the through hole 240 of the present embodiment penetrates the first side portion 204A in the front-rear direction.

[0052] As shown in FIG. 21, in the present embodiment, the portion to be pressed 252A faces forward in the front-rear direction. The portion to be pressed 252A has a flat plate shape. Referring to FIGS. 17 and 21, the portion to be pressed 252A is located at the right end of the first side portion 204A in the left-right direction.

[0053] As shown in FIG. 15, a portion to be locked 270 is provided on the first side portion 204A. That is, the portion to be locked 270 is provided on the antenna body 200A. The portion to be locked 270 is a plane facing rearward in the front-rear direction. The portion to be locked 270 is located to the left of the through hole 240 in the left-right direction. The portion to be locked 270 is located at the same position as the through hole 240 in the up-down direction. The portion to be locked 270 is adjacent to the through hole 240 in the left-right direction.

[0054] As shown in FIG. 17, the arm portion 210A of the present embodiment extends from the first side portion 204A. That is, the arm portion 210A extends from the antenna body 200A. The arm portion 210A extends rightward from the right end of the first side portion 204A, then bends forward, and further extends leftward. A part of the arm portion 210A is located in front of the first side portion 204A in the front-rear direction. As understood from FIGS. 10 and 13, the arm portion 210A is elastically deformable. A locking portion 2152 is provided at the end portion 215 of the arm portion 210A.

[0055] As shown in FIG. 15, the locking portion 2152 of the present embodiment faces forward in the front-rear direction. The locking portion 2152 is located at the left end of the arm portion 210A in the left-right direction. Referring to FIGS. 15 and 16, the locking portion 2152 is located to the left of the pressing portion 212A in the left-right direction. As shown in FIG. 12, the locking portion 2152 locks the portion to be locked 270.

[0056] As shown in FIG. 16, the pressing portion 212A of the present embodiment faces rearward in the front-rear direction. Referring to FIGS. 15 and 16, the pressing portion 212A is located near the center in the left-right direction of the arm portion 210A. The pressing portion 212A is supported by the arm portion 210A. The pressing portion 212A is integrally formed with the arm portion 210A. That is, the pressing portion 212A is integrally formed with the antenna body 200A (see FIG. 14). The pressing portion 212A is located at the same position as the portion to be pressed 252A in the up-down direction. The pressing portion 212A is located at the same position as the portion to be pressed 252A in the left-right direction. The pressing portion 212A is located in front of the portion to be pressed 252A in the front-rear direction. Referring to FIG. 13, in the up-down direction, the size of the pressing portion 212A is larger than the size of the locking portion 2152.

[0057] As shown in FIG. 12, the conductive film 500A is partially sandwiched between the pressing portion 212A and the portion to be pressed 252A. That is, the pressing portion 212A presses the conductive film 500A against the portion to be pressed 252A, whereby the conductive film 500A and the portion to be pressed 252A are electrically connected. More specifically, the pressing portion 212A presses the conductive film 500A against the portion to be pressed 252A along the front-rear direction, whereby the conductive film 500A and the portion to be pressed 252A are electrically connected. Here, as described above, the locking portion 2152 locks the portion to be locked 270. Thereby, the electrical connection between the conductive film 500A and the portion to be pressed 252A is maintained.

[0058] Referring to FIGS. 15 and 16, in the state before the locked portion 270 is locked by the locking portion 2152, the distance Ds between the pressing portion 212A and the pressed portion 252A is larger than the thickness T of the conductive film 500A. Also, referring to FIGS. 16, 20, and 21, in the state where the locking portion 2152 locks the locked portion 270 without sandwiching the conductive film 500A between the pressing portion 212A and the pressed portion 252A, the distance Ds between the pressing portion 212A and the pressed portion 252A is smaller than the thickness T of the conductive film 500A. Thus, as shown in FIG. 12, when the locking portion 2152 locks the locked portion 270 with the conductive film 500A positioned between the pressing portion 212A and the pressed portion 252A, the conductive film 500A will be partially sandwiched between the pressing portion 212A and the pressed portion 252A.

[0059] Referring to FIG. 17, the conductive film 500A of the present embodiment is the same as the conductive film 500 of the first embodiment except that it does not have the cut 510. Therefore, detailed description thereof is omitted.

[0062] First, referring to FIG. 17, the antenna member 150A and the conductive film 500A are prepared. Here, in the antenna member 150A in the state before the locked portion 270 is locked by the locking portion 2152, there is a space 220A between the pressing portion 212A and the pressed portion 252A (see FIG. 16).

[0063] Next, the conductive film 500A is bent so that a part of the conductive film 500A extends upward. Then, the conductive film 500A is disposed below the antenna member 150A so that the above-mentioned part of the conductive film 500A is positioned directly below the space 220A. Thereby, the antenna assembly 100A is in the state of FIG. 17.

[0064] Thereafter, the conductive film 500A is moved upward with respect to the antenna member 150A. As a result, the antenna assembly 100A assumes the state shown in FIG. 13. In this state, the above-mentioned part of the conductive film 500A is located between the pressing portion 212A and the pressed portion 252A.

[0065] In the state shown in FIG. 13, when the left end of the arm portion 210A is pushed backward and the locking portion 2152 is inserted into the through hole 240, the locking portion 2152 locks the locked portion 270. As a result, the antenna assembly 100A assumes the state shown in FIGS. 10 to 12. In this state, the pressing portion 212A presses the conductive film 500A against the pressed portion 252A, whereby the conductive film 500A and the pressed portion 252A are electrically connected. Thus, in the antenna assembly 100A of the present embodiment, the structure does not require soldering or the like to fix the conductive film 500A to the antenna body 200A. That is, in the antenna assembly 100A of the present embodiment, the workability in the operation of fixing the conductive film 500A to the antenna body 200A is improved.

[0066] As described above, the present invention has been specifically described with reference to the embodiments. However, the present invention is not limited to this, and various modifications are possible.

[0067] In the antenna assembly 100 of the first embodiment, the combination of the pressing portion 212 and the pressed portion 252 is two, but the present invention is not limited to this. That is, the antenna assembly 100 212 and the pressed portion 252 only needs to have only one combination.

[0068] In the antenna assembly 100A of the second embodiment, the pressing portion 212A and the pressed portion 252A were each one, but the present invention is not limited to this. That is, the antenna assembly 100A may have two combinations of the pressing portion 212A and the pressed portion 252A. In this case, each of the two combinations will electrically connect the antenna body 200A and the conductive film 500A.

[0069] In the antenna assembly 100A of the second embodiment, a hole corresponding to the receiving hole 250 of the first embodiment was not formed in the first side portion 204A of the antenna body 200A, but the present invention is not limited to this. That is, the antenna assembly 100A may be deformed such that a hole corresponding to the receiving hole 250 is formed in the first side portion 204A. In this modification, the pressed portion 252A will be provided at the edge of the hole, as in the first embodiment, and a part of the conductive film 500A will be pushed into the hole when the pressing portion 212A presses the conductive film 500A against the pressed portion 252A.
