Abstract

According to one embodiment, an antenna incorporated in an electronic apparatus includes an antenna element formed of a metal thin film and provided on the inner surface of a side wall of a housing, an antenna ground formed of a metal thin film and provided on the inner surface of the bottom wall of the housing, and a conductor portion formed of a metal thin film, provided at least on the inner surface of the bottom wall and connecting the antenna element to the antenna ground. The feed pin of a feed terminal mounted on a printed circuit board is kept in contact with the conductor portion on the bottom wall to feed power from a wireless module to the antenna.

Claims

1. An electronic apparatus comprising:

a first case including a wall portion;

an antenna element of a metal thin film, provided on an inner surface of the wall portion;

a ground portion provided close to the antenna element on the inner surface of the wall portion;

a conductor portion provided on the inner surface of the wall portion and connected to the antenna element and the ground portion;

a circuit board including a mount surface opposed to the wall portion, on which a feed portion electrically connected to the conductor portion, the circuit board being fixed to the wall portion in a different position than that of the feed portion so that the circuit board keeps the feed portion in contact with the conductor portion.

2. The electronic apparatus of claim 1, wherein the feed portion includes a feed pin conductive with the conductor portion, and a holding sleeve fixed to the circuit board and holding the feed pin so that the feed pin can project and retract, the holding sleeve urging the feed pin to be pressed against the conductor portion.

3. The electronic apparatus of claim 1, further comprising a first support member interposed between the wall portion and the circuit board between a position where the circuit board is fixed to the wall portion and the feed portion, the first support member including an end kept in contact with the wall portion and another end kept in contact circuit board.

4. The electronic apparatus of claim 3, wherein the first support member is provided along a plane direction of the wall portion, at a position where a pressure of contact of the feed portion against the conductor portion can be set at an appropriate value.

5. The electronic apparatus of claim 4, further comprising:

a second case between which and the wall portion the circuit board is interposed; and

a second support member contacting an inner surface of the second case and a surface of the circuit board of which opposite surface contacting the first support member.

6. An electronic apparatus comprising:

a first case including a wall portion;

an antenna element of a metal thin film, provided on an inner surface of the wall portion;

a ground portion provided close to the antenna element on the inner surface of the wall portion;

a conductor portion provided on the inner surface of the wall portion and connected to the antenna element and the ground portion;

a circuit board including a mount surface opposed to the wall portion and a fixing portion fixed to the wall portion; and

a feed portion interposed between the circuit board and the wall portion, the feed portion electrically connecting the mount surface and the conductor portion in a different position than that of the fixing portion.

7. The electronic apparatus of claim 6, wherein the feed portion includes a feed pin conductive with the conductor portion, and a holding sleeve fixed to the circuit board and holding the feed pin so that the feed pin can project and retract, the holding sleeve urging the feed pin to be pressed against the conductor portion.

8. The electronic apparatus of claim 7, further comprising a first support member interposed between the wall portion and the circuit board and between a position where the circuit board is fixed to the wall portion and the feed portion, the first support member including an end kept in contact with the wall portion and another end kept in contact with the circuit board.

9. The electronic apparatus of claim 8, wherein the first support member is located along a plane direction of the wall portion, at a position where a pressure of contact of the feed portion against the conductor portion can be set at an appropriate value.

10. The electronic apparatus of claim 9, further comprising:

a second case between which and the wall portion the circuit board is interposed; and

a second support member contacting an inner surface of the second case and a surface of the circuit board of which opposite surface contacting the first support member.

11. An electronic apparatus comprising:

a first case including a wall portion;

an antenna comprises

an antenna element made of a conductive material, the antenna element being provided on an inner surface of the wall portion;

a ground portion provided adjacent to the antenna element on the inner surface of the wall portion;

a conductor portion provided on the inner surface of the wall portion and coupled to the antenna element and the ground portion; and

a circuit board including a feed portion electrically coupled to the conductor portion, the circuit board being fixed to the wall portion at a position different than that of the feed portion and maintaining the feed portion in contact with the conductor portion.

12. The electronic apparatus of claim 11, wherein the feed portion includes a feed pin and a holding sleeve fixed to the circuit board and holding the feed pin to be electrically coupled with the conductor portion.

13. The electronic apparatus of claim 12, wherein the holding sleeve of the feed portion holds the feed pin so that the feed pin is able to axially project and retract.

14. The electronic apparatus of claim 11, further comprising a first support member interposed between the wall portion and the circuit board and between the position where the circuit board is fixed to the wall portion and the feed portion, the first support member including a first end in contact with the wall portion and a second end in contact with the circuit board.

15. The electronic apparatus of claim 14 further comprising a second support member including a first end in contact with the wall portion and a second end in contact with the circuit board, the first support member and the second support member being positioned to set and control a pressure of contact of the feed portion against the conductor portion.

16. The electronic apparatus of claim 15, further comprising:
