Abstract:
1. A non-contact wireless communication apparatus comprising: an antenna section configured to receive a carrier wave; an envelope-curve shaping section configured to shape a falling waveform of an envelope curve of the carrier wave into a gradual falling waveform; and a demodulation section configured to extract the envelope curve shaped by the envelope-curve shaping section and perform envelope-curve detection by binarizing the envelope curve with a predetermined threshold value, wherein the envelope-curve shaping section is made up of a diode, a capacitor, and a resistor, and an anode of the diode is connected to an antenna line of the antenna section, a cathode of the diode is connected to a first end of the capacitor, a second end of the capacitor is connected to ground, a first end of the resistor is connected to the antenna line of the antenna section, and a second end of the resistor is connected to a connection point between the cathode of the diode and the first end of the capacitor, such that the diode and the resistor are connected in parallel between the antenna line and the capacitor.
