Claim:
1. A circuit arrangement comprising: a first antenna tuned to a first frequency range; a second antenna tuned to a second frequency range being different from the first frequency range; wherein the second antenna is configured as a dipole antenna; a first controller coupled to the first antenna and the second antenna, wherein the first controller is configured to receive its operational power via at least one of the first antenna and the second antenna; wherein the first controller is connected to at least one of the first antenna and the second antenna; and a deactivating structure configured to deactivate communication of the first controller via the second antenna upon reception of electromagnetic waves with the first frequency range via the first antenna, wherein the deactivating structure comprises a rectifier coupled to the first antenna and a switch coupled to the second antenna and configured to short circuit the second antenna; wherein the rectifier is coupled to a control terminal of the switch; wherein the second antenna is tuned to frequency from an ultra high frequency range.
