Patent ID: 7502598

Claim:
A receiving arrangement, comprising: a radio-frequency antenna arrangement configured to receive radio-frequency signals, comprising a tuning connection for tuning a resonant frequency of the radio-frequency antenna arrangement, and comprising at least one connection for emission of a received signal; a tuning circuit configured to tune a frequency of the radio-frequency antenna arrangement, comprising a control input and at least one tuning element coupled to the tuning connection of the radio-frequency antenna arrangement as a function of a tuning signal; a filter device configured to suppress signal components in the received signal, comprising an input and an output, wherein the input is coupled to at least one connection of the radio-frequency antenna arrangement; at least one matching apparatus connected between the input of the filter device and the at least one connection of the radio-frequency antenna arrangement, and configured to control a matching of an output impedance of the radio-frequency antenna arrangement to an input impedance of the filter device; and a control device comprising a first output for a control signal connected to the control input of the tuning circuit, and comprising a second output and providing a matching signal thereat, wherein the second output is connected to the matching apparatus, and wherein the control device is configured to produce and emit the control signal and the matching signal as a function of at least one predetermined parameter, wherein the output of the matching apparatus is connected to the input of the filter device without any impedance transformation circuit therebetween.
