摘要： A power splitter for a smart card having near field RF communications capability, the power splitter comprising a substrate for integration into said smart card; a first port for connection to a near field RF communications antenna for receiving an alternating electrical signal; a second port for connection to an auxiliary rectifier; and a third port for connection to a near field RF communicator; wherein the splitter comprises a impedance network, connected between the three ports, and being arranged to divide the alternating electrical signal between the second port and the third port to split the alternating electrical signal, wherein the impedance network comprises a printed coil inductor, and a zone of the substrate surrounding the printed coil inductor is free from any ground plane.
