Abstract

A vehicle-mounted antenna for a vehicle-mounted information processing device performs wireless communication within a vehicle between the vehicle-mounted information processing device located at a rear side of a veneer plate and another electronic circuit within the vehicle. The vehicle-mounted information processing device reads data from a medium inserted via a media insertion opening formed in the veneer plate and executes various processing based on the read-in data. The vehicle-mounted antenna is arranged deeper than the media insertion opening, within a region set if the media insertion opening is extended in a direction substantially orthogonal with the veneer plate.

Claims

1. A vehicle-mounted antenna for a vehicle-mounted information processing device, for performing wireless communication within a vehicle between the vehicle-mounted information processing device located at a rear side of a veneer plate and another electronic circuit within the vehicle, with the vehicle-mounted information processing device reading data from a medium inserted via a media insertion opening formed in the veneer plate and executing various processing based on the read-in data, wherein:

the vehicle-mounted antenna is arranged deeper than the media insertion opening, within a region set if the media insertion opening is extended in a direction substantially orthogonal with the veneer plate;

the vehicle-mounted antenna is located on a substrate of the vehicle-mounted information processing device, and

the media insertion opening is always open.

2. A vehicle-mounted antenna according to claim 1, wherein:

the vehicle-mounted antenna is provided on an upper side from a media insertion path from the media insertion opening to a media reading position.

3. A vehicle-mounted antenna according to claim 1, wherein:

the vehicle-mounted antenna is located in a position in such a manner that an antenna radiation direction towards a vehicle interior through the media insertion opening does not overlap with the medium when the medium is inserted as far as a media reading position.

4. A vehicle-mounted antenna according to claim 1, wherein:

a periphery of the media insertion opening is constructed from a veneer plate made using a material that blocks electromagnetic waves.

5. A vehicle-mounted antenna according to claim 1, wherein:

the vehicle-mounted antenna is a high-frequency wireless communication antenna.

6. A vehicle mounted antenna according to claim 1, wherein the media insertion opening is provided on a dashboard of the vehicle, and wherein the vehicle-mounted antenna is disposed within the dashboard.

7. A vehicle mounted antenna according to claim 1, wherein the veneer plate corresponds to a portion of a dashboard of the vehicle.

8. A vehicle mounted antenna according to claim 1, wherein the media insertion opening is configured to accept a storage disk for playing by a disk player disposed within a dashboard of the vehicle.

9. A vehicle mounted antenna according to claim 1, wherein the vehicle-mounted antenna is positioned to face a vehicle interior compartment corresponding to a region where a driver of the vehicle is located when operating the vehicle, so as to be positioned to receive wireless signals output by a mobile telephone located within the vehicle interior compartment.

10. A vehicle mounted antenna according to claim 1, wherein the substrate comprises a communications circuit.

11. A vehicle mounted antenna according to claim 10, wherein the communications circuit is mounted on a printed circuit board.

12. A vehicle mounted antenna according to claim 1, wherein, due to the media insertion opening being always open, the antenna always has an antenna radiation pattern that extends outward from the media insertion opening and into a front side of the veneer plate.
