Abstract: A communication apparatus that comprises a second coupler to be coupled to a first coupler of a different communication apparatus by electric field coupling and/or inductive coupling, a termination resistor connected to the second coupler and having a resistance value larger than a predetermined value is provided. The communication apparatus receives a signal comprising (i) an output signal that is output from the second coupler in response to input of a transmitted signal to the first coupler, (ii) a signal obtained by performing amplification processing on the output signal, or (iii) a signal obtained by shaping, via a comparator, a signal obtained by performing amplification processing on the output signal, and processes the received signal as a signal that is obtained by reproducing the transmitted signal.

Abstract: A wireless communication apparatus includes a first conductor and a second conductor that function as a set of electrodes for wireless communication, a third conductor and a fourth conductor that function as another set of electrodes for wireless communication. A difference between a first distance between a centroid of the first conductor and a centroid of the third conductor and a second distance between a centroid of the second conductor and the centroid of the third conductor is less than a width of the first conductor and a width of the second conductor. A third distance between the centroid of the first conductor and a centroid of the fourth conductor is longer than the first distance. A fourth distance between the centroid of the second conductor and the centroid of the fourth conductor is longer than the second distance.

Abstract: A power transmission unit includes an alternating-current power source that outputs alternating-current power, a clock generation unit that generates a clock signal higher in frequency than the alternating-current power, and a power transmission antenna that wirelessly transmits the power. A power reception unit includes, a power reception antenna that receives wirelessly the power from the power transmission antenna, and a rectification circuit that rectifies a voltage output from the power reception antenna and outputs the alternating-current power. A control system includes a correction unit that estimates a property change in one or more passive elements included in at least one of the power transmission unit or the power reception unit, and corrects a phase of the clock signal or the alternating-current power output from the alternating-current power source to maintain linearity between the alternating-current power output from the alternating-current power source and the alternating-current power output from the rectification circuit.
