Abstract

The invention relates to a repeater system (1) for relaying the exchanges between a base station mobile telecommunication network and a user terminal, comprising an outside antenna (10) that can communicate with the base station, as well as retransmission means (20) connected to the outside antenna, wherein the retransmission means (20) are designed to act as the interface between the outside antenna (10) and an inside antenna (30) that can communicate with the user terminal to retransmit the signals received by either one of the antennae destined for the other antenna, characterised in that the outside antenna is an optically transparent planar antenna integrated into an optically transparent panel (2) used for the indoor lighting of a building

Claims

1. Repeater system (1) for relaying the exchanges between a base station of a mobile telecommunication network and a user terminal, comprising an outside antenna (10) that can communicate with the base station, as well as retransmission means (20) connected to the outside antenna, wherein the retransmission means (20) are designed to act as the interface between the outside antenna (10) and an inside antenna (30) that can communicate with the user terminal to retransmit the signals received by one of the antennae destined for the other antenna, characterised in that the outside antenna is an optically transparent planar antenna integrated into an optically transparent panel (2) used for the indoor lighting of a space.

2. System according to claim 1, in which the outside antenna comprises an earth plane (11), a radiating plane in the form of one or several radiating elements (12-15), and in which one part (3) of the panel is interposed between the earth plane and the radiating plane to form a dielectric substrate on the outside antenna.

3. System according to claim 2, in which the earth plane (11) and the radiating element(s) (12-15) of the radiating plane are each formed by the depositing of an optically transparent conductive material.

4. System according to claim 3, in which said material is tin oxide doped with silver (AgHT) or indium-tin oxide (ITO).

5. System according to any of claims 2 to 4, in which the earth plane (11) and the radiating plane (12-15) are sandwiched between the optically transparent dielectric layers (4, 5) of the panel (2).

6. System according to any of claims 1 to 5, in which the panel (2) is made of glass.

7. System according to any of claims 1 to 6, in which the panel is part of a window type construction element with an opaque frame (6), and in which the outside antenna (10) has power supply means (16) inside the frame.

8. System according to claim 7, in which the power supply means (16) are in the form of a circuit (17) printed onto a dielectric substrate.

9. System according to claim 7, in which the power supply means are in the form of a power supply by coaxial probe (16).

10. System according to any of claims 1 to 9, in which the panel (2) is part of a window type construction element with an opaque frame (6), wherein the inside antenna (30) is integrated into the frame.

11. System according to any of claims 1 to 9, in which the inside antenna (30) is an optically transparent planar antenna integrated into the panel (2).

12. Window type construction element in which a system according to any of claims 1 to 11 is integrated.
