<p>A high-frequency coupler includes ground; a coupling electrode being supported so that the coupling electrode is placed opposite the ground and separately placed at a height from the ground, the height being negligible relative to the wavelength of the high-frequency signal; a resonator increasing electric current entering the coupling electrode through a transmission path; and a stretchable/retractable connection section connecting a predetermined position on the coupling electrode and the resonator; wherein an infinitesimal dipole is formed, the infinitesimal dipole including a line segment which connects the center of electric charge accumulated in the coupling electrode and the center of mirror-electric charge accumulated in the ground, and the high-frequency signal is transmitted to another high-frequency coupler at a communication partner side, which is placed opposite the high-frequency coupler so that the angle between the direction of the infinitesimal dipole and the direction from the high-frequency coupler toward the other high-frequency coupler is nearly zero.</p> |
