Patent ID: 7513434

Claim:
A device for processing a signal, the device comprising: an antenna configuration; and a circuit; wherein the antenna configuration is arranged to transmit a signal, the antenna configuration having at least one antenna-configuration terminal that is intended for connecting the antenna configuration to the circuit and the antenna configuration having an antenna-configuration impedance (ZA) at the antenna-configuration terminal; wherein the circuit has at least one circuit terminal at which the circuit has a circuit impedance (ZS) and at which the circuit is connected to the antenna-configuration terminal for the purpose of power transmission between the antenna configuration and the circuit by using the signal, wherein at least one of the two impedances (ZA, ZS) has, in respect of its reactance(YA, YS), a difference in reactance value (ΔY) from a nominal reactance value (Y NOM ) that is adapted for the transmission of power between the antenna configuration and the circuit, characterized in that one of the two impedances (ZA, ZS) has a resistance (XA, XS) whose value is greater than a nominal resistance value (X NOM ) that is adapted from the transmission of power between the antenna configuration and the circuit and is smaller than a maximum resistance value (X MAX ) that is a function of the difference in the reactance value (ΔY).
