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.
