摘要： An electromagnetic resonant coupler includes an input line to which a transmission signal is input; a first resonance line connected to the input line; a second resonance line opposing the first resonance line, the second resonance line undergoing resonant coupling with the first resonance line to thus wirelessly transmit the transmission signal between the first resonance line and the second resonance line; an output line connected to the second resonance line, the transmission signal being output through the output line; a coupling line that electromagnetically couples with at least one selected from the group consisting of the first resonance line and the second resonance line; and a terminator connected to one end of the coupling line.
