PROBLEM TO BE SOLVED: To provide an electric field resonance coupler capable of suppressing occurrence of unnecessary resonance, even if transmission and reception are performed using a coaxial cable having a grounded outer conductor.SOLUTION: An electric field resonance coupler 100 is constituted so that a link coil 115 and a capacitor 116 for impedance adjustment, and a link coil 125 and a capacitor 126 for impedance adjustment are disposed, respectively, between the resonance coils 113 and 114 of a transmission coupler 110, and between the resonance coils 123 and 124 of a reception coupler 120. The link coil 115 and capacitor 116, and the link coil 125 and capacitor 126 are connected in series, respectively. Coaxial cables 11 and 21 are connected, respectively, with the link coil 115 and capacitor 116, and the link coil 125 and capacitor 126.SELECTED DRAWING: Figure 1 |
