Abstract
In a circuit for reception of signals which have been modulated onto electromagnetic waves, an antenna arrangement () having a variable resonant frequency, a tunable oscillator, a variable gain amplifier, an evaluation circuit () and a decoder () are provided. The evaluation circuit () is supplied with the control signals of the oscillator (VT) and of the amplifier (VAGC) and with an error rate signal (BER) from the decoder (). The resonant frequency of the antenna arrangement () is varied as a function of the signals which are applied to the evaluation circuit (), such that the resonant frequency of the antenna arrangement () is matched to the respective reception conditions. This makes it possible to compensate for changes in the reception conditions, such as those which are caused, for example, by people or objects in the vicinity of the antenna arrangement ().
