摘要： A communication system comprises a transmitter (1) that applies an electric field to a transmission medium, the electric field being obtained by modulating an information signal for wideband communication. The transmitter (1) has a transmission electrode (11), a transmission circuit (13) that outputs the information signal for the wideband communication, and first band controlling means (12) for controlling a band of the information signal for the wideband communication. The communication system is characterized in that , when a transmission medium (2) is in contact with the transmission electrode (11) and the transmission medium (2) and the transmission electrode (11) are capacitively coupled to each other, the band controlling means (12) performs control to provide a band that is necessary for the receiver (3) to perform demodulation for the wideband communication, and when the transmission medium (2) is not in contact with the transmission electrode (11), the first band controlling means (12) performs control to provide a narrower band than the band that is necessary for the receiver (3) to perform demodulation for the wideband communication.

摘要： To provide a communication system in which transmission efficiency is stable even if a stray capacitance with respect to the earth ground fluctuates, the potential variation of a transmission electrode at a carrier frequency used for communication is small, it is possible to apply the communication system to an intended purpose when being in motion, and communication can be established even if the communication system is held in such a manner that the communication system is covered by a hand. A communication system according to the present invention includes a transmitter (2) configured to provide an information signal, as an electric field, to a transmission medium (1) and a receiver configured to detect the electric field through the transmission medium (1) and obtain the information signal, and the transmitter (2) includes a resonance unit in which a resonant circuit is formed with two electrodes (221) and (222) individually forming electrostatic capacitances between the transmitter and the transmission medium and an inductor (223) connecting the two electrodes (221) and (222) to each other.
