HIGH-FREQUENCY COUPLER

WIPO Patent Application WO/2010/106996

A1

Disclosed is a high-frequency coupler used in high-frequency signal communication, that satisfies both a predetermined communication quality level and a desired thin thickness. The high-frequency coupler (1) has a circuit board (100) and a toroidal coil (220). The toroidal coil (220) extends on the top surface (110) of the circuit board (100) and is connected to the bottom surface (120) of the circuit board (100) through a through-hole (222), then extends on the bottom surface (120) and is connected to the top surface (110) through the through-hole (222), and again extends on the top surface (110), which are similarly repeated thereafter between the top surface (110) and bottom surface (120). Consequently, the toroidal coil (220), while straddling the top surface (110) and the bottom surface (120), goes around and makes a round as a whole like drawing a circle on the circuit board (100). In addition, at the midpoint of the round on the circuit board (100), the toroidal coil (220) reverses the revolving direction straddling the top surface (110) and the bottom surface (120).
