Abstract (en)
[origin: EP2053878A2] The device has a transmitting device (16) including an antenna for wireless sending of electromagnetic data. A switching regulator (14) includes an inductor (15) for power supply of the device and the transmitting device. The inductor is identical with the antenna of the transmitting device, and includes a ring core, which is partially opened. Pulse width modulation, pulse frequency modulation or amplitude modulation is used in the switching regulator for the power supply, and frequency modulation or phase modulation is used in the transmitting device for data transmission.
