Document Type and Number:
WIPO Patent Application WO/2021/111761
Kind Code:
A1
Abstract:
A layered filter (1) is provided with a first ground electrode (111), a second ground electrode (112), a first LC resonator (LC1) and a second LC resonator (LC2). The first LC resonator (LC1) includes a first line electrode (101), a first capacitor electrode (102), a first via conductor (V11) and a second via conductor (V12). The second via conductor (V12) extends from the first line electrode (101) to the side where the first capacitor electrode (102) is disposed, and connects the first line electrode (101) and the first ground electrode (111). The second LC resonator (LC2) includes a second line electrode (201), a second capacitor electrode (202), a third via conductor (V21), and a fourth via conductor (V22). The fourth via conductor (V22) extends from the second line electrode (201) to the side where the second capacitor electrode (202) is disposed, and connects the second line electrode (201) and the second ground electrode (112).
