Abstract
The wireless data communication device () is mounted in a portable object, such as a wristwatch. The device includes an oscillator circuit (), which produces high frequency signals (S), and a signal processing unit (), connected to the oscillator circuit. The connection structure of one part of the oscillator circuit (), which produces the high frequency signals, is arranged to act as antenna for the transmission of data by means of stray signals (S) transmitted by the connection structure. The processing unit provides a control signal (C) to the oscillator circuit depending upon the data to be transmitted by means of the stray signals by the connection structure. An amplitude modulation or a frequency modulation can be used for the transmission of data by means of the stray signals.
