Patent ID: 8634764

Claim:
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, wherein the outside antenna is an optically transparent planar antenna integrated into an optically transparent panel ( 2 ) used for the indoor lighting of a space, the outside antenna comprising an earth plane ( 11 ) and a radiating plane in the form of one or several radiating elements ( 12 - 15 ), the earth plane ( 11 ) and the radiating element(s) ( 12 - 15 ) of the radiating plane are each formed by depositing an optically transparent conductive material, and wherein the panel is part of a window type construction element having an opaque frame ( 6 ), inside which a power supply is fitted for electro-magnetically exciting for the one or several radiating elements of the outside antenna.
