Abstract

A communication device having an antenna resonant circuit, an antenna driver which is configured to feed a carrier wave to the antenna resonant circuit, and a controller which is configured to detect that a synchronization period is imminent and is configured to control the antenna driver in such a way that the antenna driver feeds the inverted carrier wave to the antenna resonant circuit.
