Abstract: Various embodiments provide a communication module having a carrier, a loop antenna, a modulation circuit which is coupled to the loop antenna and is configured to modulate or demodulate signals which are received or transmitted using the loop antenna, and an impedance matching circuit for matching the impedance of the loop antenna to the input impedance of the modulation circuit. The modulation circuit and the impedance matching circuit are arranged inside the loop antenna on or in the carrier.

Abstract: A circuit arrangement is provided, having an antenna, a first circuit coupled to the antenna and configured to receive an antenna signal, which contains first data, and to process the antenna signal, as a result of which it produces a processed antenna signal having a different voltage level than that of the antenna signal. The first data are data transmitted from a communication device to the arrangement. The arrangement further includes a second circuit coupled to the first circuit via a wire-based interface. The first circuit is configured to transmit the processed antenna signal to the second circuit by a first channel of the wire-based interface and the second circuit is configured to transmit second data to the first circuit by a second channel of the wire-based interface. The first channel and the second channel are different. The second data are configuration data for configuring the first circuit.
