Abstract

A portable device for a vehicle includes a short range communication antenna, a near field communication antenna, and a housing case. The short range communication antenna is utilized in a short range wireless communication with a communication device equipped to a vehicle. The near field communication antenna is utilized in a near field wireless communication. The short range communication antenna is disposed in the housing case. The near field communication antenna is disposed on the housing case by decorative printing. A communicable range of the short range wireless communication is longer than a communicable range of the near field wireless communication.

Claims

1. A portable device for a vehicle comprising:

a short range communication antenna utilized in a short range wireless communication with a communication device equipped to a vehicle;

a near field communication antenna utilized in a near field wireless communication; and

a housing case;

wherein the short range communication antenna is disposed in the housing case,

wherein the near field communication antenna is disposed on the housing case by decorative printing,

wherein the housing case includes an external film layer, a decorative printing layer, an internal film layer, and an antenna printing layer laminated in order in a direction from an outside portion of the housing case to an inside portion of the housing case, and

wherein the near field communication antenna is provided by the antenna printing layer.

3. The portable device according to claim 1, further comprising

a substrate on which the short range communication antenna is disposed,

wherein the near field communication antenna includes an antenna terminal provided by the antenna printing layer,

wherein the substrate includes a substrate side terminal that is connected with the antenna terminal of the near field communication antenna,

wherein the housing case further includes a base resin portion disposed on a surface of the antenna printing layer opposed to the substrate,

wherein the base resin portion defines a through hole at a position corresponding to the antenna terminal of the near field communication antenna so that the through hole penetrates the base resin portion, and

wherein the antenna terminal of the near field communication antenna is connected with the substrate side terminal via a contact spring.

4. The portable device according to claim 1, wherein a communicable range of the short range wireless communication is longer than a communicable range of the near field wireless communication.
