| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In duplex wireless power transmission using electromagnetic resonant coupling, a method of reducing interference by adding a directional coupler is proposed. If duplex wireless power transmission has no loss and is perfectly matched, it acts as a directional coupler. The present method uses this characteristic and the interference is decreased by connecting a directional coupler to the input or output ports of duplex wireless power transmission. We validate this method by performing simulations for two configurations of duplex wireless power transmission, one is duplicating horizontally the simplex transmission in which two antennas are set opposite each other, and the other is duplicating axially the simplex transmission in which two antennas are put on concentric circles. Also, it is shown that the isolation port changes depending on the transmitting distance in the former configuration. | |
