In one embodiment of the present invention, a wireless interface is provided for supplying all signals and power exclusively wirelessly from a transmitting section to a receiving section. The transmitting section includes a transmitter arranged to modulate a carrier with signals, such as data, control and timing signals. The transmitter is connected to a transmit antenna which comprises a parallel resonant circuit in series with a series resonant circuit. The parallel and series resonant circuits include inductors which are inductively coupled to an inductor of a receive antenna in the receiving section.
