Abstract
A transmitter circuit. One embodiment provides for emitting electromagnetic waves. The circuit has a transmitting device for outputting a transmission signal, an antenna device for emitting the transmission signal in the form of an electromagnetic wave, and a matching device which is electrically connected to the transmitting device and to the antenna device. The matching device includes at least two tuning elements for setting the resonant frequency of a circuit arrangement, formed from the antenna device and the first and second tuning elements, and for matching the impedance of the transmitting device and the antenna device.
