Abstract (en)

[origin: EP0718908A1] The circuit comprises a transmit circuit (10) for the production of the RF signal. Furthermore said arrangement comprises an antenna (24) for the radiation of the RF signal and an impedance matching circuit (22) placed between the antenna (24) and the output (20) of the transmit circuit (10). A battery (24) serves for the application of the operating or power voltage between a positive operating voltage line (12) and the ground line (16) are decoupled from the battery (24) with respect to the RF signal and the RF signal is applied by the output (20) of the transmit circuit (10) to the positive terminal of the battery (24) so that the part connected with such terminal of the battery (24) constitutes the antenna. <IMAGE>
