Abstract

This invention relates generally to a multiservice antenna system assembly. The multiservice antenna system assembly may include one antenna that is fastened by means of a support, or at least two antennas that are grouped together by means of a support. The support may, for example, be a plastic packing. This invention is particularly useful when the antenna assembly is located in automobile rear-view mirrors and more particularly in exterior rear-view mirrors.

Claims

1. A multiservice antenna system assembly comprising:

at least a first printed circuit board and a second printed circuit board, each of said first and second printed circuit boards comprising at least one antenna, and

a support member made of a plastic material and configured to be mounted inside a rearview mirror of a motor vehicle,

wherein said at least first and second printed circuit boards are supported by said support member, and lie in substantially parallel planes,

wherein said at least one antenna on said first printed circuit board is disposed on a face of the first printed circuit board and comprises a radio FM antenna shaped as a space-filling curve,

wherein said at least one antenna on said second printed circuit board is disposed on a face of the second printed circuit board and comprises a telephone antenna,

wherein at least said first printed circuit board further comprises at least one electronic component, and

wherein said support member is overmolded over said first printed circuit board and over said at least one electronic component, so that said first printed circuit board is at least partially embedded within said support member.

2. The multiservice antenna system assembly according to claim 1 wherein said space-filling curve has a box-counting dimension larger than 1.5 or a grid dimension larger than 1.5.

3. The multiservice antenna system assembly according to claim 1 or 2, wherein said space-filling curve is substantially a Hilbert curve.

4. The multiservice antenna system assembly according to claim 1, which provides at least one communication or positioning services selected from a group consisting of:

i) a radio communication service, ii) a telephone communication service, iii) a GPS positioning service.

5. The multiservice antenna system assembly according to claim 1, which provides a communication service selected from a group consisting of:

DTB, PCS1900, KPCS, CDMA, WCDMA, TDMA, UMTS, TACS, ETACS, SDARS, WiFi, WiMAX, UWB, Bluetooth, and ZigBee.

6. The multiservice antenna system assembly according to claim 1, wherein said telephone antenna is a GSM dual band antenna or a multiband antenna for cellular telephony.

7. A rear-view mirror assembly for a motor vehicle, comprising the multiservice antenna system assembly according to claim 1.

8. The rear-view mirror assembly according to claim 7 wherein said support member is housed within the rear-view mirror assembly.

9. The rear-view mirror assembly according to claim 7 or claim 8 further comprising a GPS antenna.

10. The rear-view mirror assembly according to claim 9 wherein said GPS antenna is a microstrip patch antenna.

11. The rear-view mirror assembly according to claim 7, wherein the multiservice antenna system assembly is mounted on a metallic internal bracket of said mirror assembly.

12. The rear-view mirror assembly according to claim 11, further comprising a GPS antenna housed within a waterproof package, wherein said package is fixed to the metallic internal bracket of said mirror assembly.

13. The rear-view mirror assembly according to claim 7, which is an external rear-view mirror assembly.

14. A vehicle comprising a rear-view mirror assembly according to claim 7.
