Abstract
In this paper, we analyzed the frequency characteristics of hexagonal spiral thin-film inductor based on non-contact AC coupling for wireless signal transmission. We compared and analyzed the frequency characteristics of the rectangular spiral inductor and the hexagonal spiral inductor according to the number of turns, the line width and the line spacing of the conductor. Hexagonal spiral inductor has more number of turns to has the same inductance as rectangular spiral inductor, but the overall length of the conductors is shortened. This reduces the self inductance and increases the mutual inductance so that the overall inductance can have the same value. Also, since the overall length of the conductor is shortened and the magnetic resistance is reduced, the quality factor and the self-resonant frequency performance can be secured. The proposed hexagonal spiral thin-film inductor has the inductance of 3.54nH at 2GHz, the quality factor of max 14.00 at 5.0GHz and the self-resonant frequency at about 11.3GHz.
