Title:
LOOP ANTENNA AND DESIGN METHOD FOR LOOP ANTENNA
Document Type and Number:
WIPO Patent Application WO/2018/235631
Kind Code:
A1
Abstract:
In the present invention, even if a capacitor C1 connected to a main loop 1 and/or a capacitor C2 connected to an amplification loop 2 cannot be set to an optimal capacitance value, it is possible to make the value of current I2 flowing through the amplification loop sufficiently large by setting the capacitors C1, C2 on the basis of a best C2 curve, a best C1 curve, or a best C1 line that, in the drawing showing the relationship between the capacitance values of the capacitors C1, C2 and the magnitude of current I2, traces the ridge of a contour line that connects points of equal magnitude of current I2, while passing through optimal points (C1 opt, C2 opt) of the capacitors C1, C2.
