摘要：An NFC communicator has an antenna circuit (102) to enable inductive coupling,via an RF H field, of the NFC communicator and another near field RF communicator innear field range. The antenna circuit has an antenna element (309) coupled in parallelwith a first capacitor (304) to form a parallel LC circuit. The antenna element has anantenna coil (308) in series with a second capacitor (307) to reduce the voltage to whichcircuitry of the NFC communicator is subjected by a received RF H field. Alternatively oradditionally, receive circuitry (119, 114) of the NFC communicator may be coupled to onlya proportion of the antenna coil to reduce the voltage to which circuitry of the NFCcommunicator is subjected by a received RF H field.
