Document Type and Number:
WIPO Patent Application WO/2020/066804
Kind Code:
A1
Abstract:
The present invention comprises: a main line path (11) through which a main signal (31) flows; an auxiliary line path (12) through which an auxiliary signal (32) flows, the auxiliary signal (32) corresponding to the main signal (31) according to electromagnetic coupling with the main line path (11); and an inductor (13) which is connected in series to one of the main line path (11) and the auxiliary line path (12), and through which one of the main signal (31) and the auxiliary signal (32) flows. A first portion (41) of first wiring (21) constituting the inductor (13) and a second portion (42) of second wiring (22) constituting the other of the main line path (11) and the auxiliary line path (12) are electromagnetically coupled.
