Abstract
In various embodiments, a circuit arrangement is provided, including 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, a controller coupled to the first antenna and the second antenna, wherein the controller is configured to receive its operational power via at least one of the first antenna and the second antenna, and a deactivating structure configured to deactivate the communication of the controller via the second antenna upon reception of electromagnetic waves with the first frequency range via the first antenna.
