RESONANT CIRCUIT AND FILTER
Document Type and Number:
WIPO Patent Application WO/2020/134000
Kind Code:
A1
Abstract:
A resonant circuit and a filter. The resonant circuit comprises: a multi-layer helically wound inductor element (100) consisting of at least two electrically connected planar helical coils (130, 140) and a first end portion (110) and a second end portion (120) at two ends thereof; and a capacitor element (200) comprising a first electrode (210) and a second electrode (220), wherein the second electrode comprises a first sub-electrode (221) and a second sub-electrode (222), the first end portion (110) is connected to the first sub-electrode (221), the second end portion (120) is connected to the second sub-electrode (222), and projections of the at least two planar helical coils (130, 140) vertically along an axial direction of the planar helical coil form a closed pattern.
