Multiplex transmission system for wirelessly transmitting power, transmitting side multiplex transmission device and billing/information system

Abstract

A multiplex transmission system including: a primary transmission power source that feeds power of a single frequency; a transmitter-receiver system that includes plural-line transmission antennas wirelessly transmitting power from the primary transmission power source, and plural-line reception antennas receiving power from the transmission antennas that form pairs with the reception antennas; a directional coupler-type transmission power source circuit establishing resonant condition of each of the transmission antennas; and plural-line reception power source circuits establishing resonant condition of each of the reception antennas that form the pairs. The directional coupler-type transmission power source circuit includes a directional coupler-type output filter that distributes power to the respective transmission antennas.
