Abstract:
A communication device having a function for supplying electric power to a communication partner may include a non-contact control section configured to balanced-output transmission power, an antenna circuit configured to transmit the transmission power as an electromagnetic wave, and a matching circuit which is disposed between an output of the non-contact control section and an input of the antenna circuit and is configured to perform impedance matching. The matching circuit and the antenna circuit are respectively provided with two systems and circuit structures from the output of the non-contact control section to the antenna circuits via the matching circuits of the two systems are formed symmetrically.
