Timepiece with internal antenna

1. A timepiece, comprising:

a case;

a dial that is made from a nonconductive material;

a movement that is housed in the case and has a at least one motor that drives at least one staff;

a patch antenna that is disposed inside the case and at a back side of the dial; and

a battery that supplies power to the motor and is disposed at a position in the case that does not overlap the patch antenna in plan view;

wherein the position at which the battery is disposed overlaps the at least one motor in plan view.

2. The timepiece described in claim 1 , further comprising:

a receiver that processes a signal received by the patch antenna; and

a circuit board to which the receiver is mounted;

wherein the circuit board has a void at a position corresponding to the battery.

3. The timepiece described in claim 2 , wherein:

the circuit board has metal patterns;

the patch antenna is disposed at one side of the circuit board; and

the receiver is mounted at another side of the circuit board.

4. The timepiece described in claim 1 , wherein:

the movement has a plurality of motors that drive respective staffs disposed at different locations,

the dial has a first display unit at which one of the staffs is disposed and a second display unit at which another of the staffs is disposed, the first and second display units being positioned so as not to overlap; and

the patch antenna is disposed at a position that overlaps part of the first display unit and part of the second display unit.

5. The timepiece described in claim 4 , further comprising:

a receiver that processes a signal received by the patch antenna;

wherein the first display unit has a display portion in which a metal hand indicates whether the receiver is processing the signal; and

wherein, while reception and processing of the signal by the receiver is in progress, the metal hand is configured so as not to move to a position overlapping the patch antenna in plan view.

6. The timepiece described in claim 4 , further comprising:

a receiver that processes a signal received by the patch antenna;

wherein the first display unit has a signal level display portion in which a metal hand indicates a level of reception of the signal while the receiver processes the signal; and

wherein the signal level display portion is positioned so as not to overlap the patch antenna in plan view.

7. The timepiece described in claim 1 , further comprising:

a date wheel made from nonconductive material is disposed at a position overlapping, at least in part, the patch antenna in plan view.
