A timepiece with an internal antenna, comprising:
- a case that is made from a conductive material;
- a movement that is housed in the case and has a plurality of motors that drive plural staffs disposed at a plurality of locations;
- a dial that is made from a nonconductive material, the dial being transparent;
- a patch antenna that is disposed inside the case on the back side of the dial, receives radio signals transmitted from an external source, and includes a dielectric and an electrode formed on the dielectric;
- and
- a solar panel that receives light and generates power is disposed on the back side of the dial;
- wherein an opening is formed in the solar panel at a position overlapping the patch antenna in plan view;
- wherein the patch antenna is disposed separated at least a specific distance from the inside surface of the case, and
- wherein the plural staffs are disposed between the case and the patch antenna.
A timepiece, comprising:
- a case that is made at least in part from a conductive material;
- a dial that is made from a nonconductive material;
- a solar panel that has an opening and is disposed at a side opposite of a display side of the dial, the solar panel receiving light incident from the display side of the dial;
- a patch antenna that is disposed (i) at a side opposite of a light receiving side of the solar panel, (ii) at a position separated from the case, and (iii) at a position overlapping the opening in plan view;
- and
- a movement that is housed in the case.
