Abstract: An electronic component includes a filter, a first phase-shift circuit, a second phase-shift circuit, and a stack. The first phase-shift circuit includes a first inductor provided in a first path connecting an unbalanced terminal and a first balanced terminal, and a first capacitor provided between the first path and a ground in a circuit configuration. The second phase-shift circuit includes a second capacitor provided in a second path connecting the unbalanced terminal and a second balanced terminal, and a second inductor provided between the second path and the ground in the circuit configuration. The first inductor and the second inductor are arranged in a direction parallel to a stacking direction.

Abstract: In a multilayer filter, first to fourth resonant circuits are connected to an input/output portion. The input/output portion includes an input/output port group including an unbalanced port and a pair of balanced ports or an input/output port group including two pairs of balanced ports. Each of the first to fourth resonant circuits includes an inductor conductor and first and second capacitor conductors. The inductor conductor includes first and second ends. The first capacitor conductor is connected to the first end. The second capacitor conductor is connected to the second end. The second and third resonant circuits are magnetically coupled to each other. The second and third resonant circuits are arranged between the first resonant circuit and the fourth resonant circuit in a first direction. Each of first and second electrodes of a jump capacitor conductor is connected to the inductor conductors of the first and fourth resonant circuits.

Abstract: A filter device includes a ground conductor layer, at least one through hole electrically connected to the ground conductor layer, a first resonator conductor layer and a second resonator conductor layer arranged to sandwich the at least one through hole, and a stack. The first resonator conductor layer extends in a first direction becoming away from the at least one through hole, i.e., the −X direction. The second resonator conductor layer extends in a second direction becoming away from the at least one through hole, i.e., the X direction.

Abstract: The auxiliary ground layer is a part in which the main line and the sub line do not overlap in the lamination direction and is disposed to face a part in which a distance from the first ground layer and a distance from the second ground layer are different in the lamination direction. When a longer distance is set as a first distance a and a shorter distance is set as a second distance b between a distance between the non-overlapping part and the first ground layer and a distance between the non-overlapping part and the second ground layer, and a third distance between the non-overlapping part and the auxiliary ground layer is set as c, the relationship of a>c≥b is satisfied.

Abstract: An antenna device 1 has a capacitive coupling element 10 mounted on a printed circuit board 20. Strip patterns 21 to 23 are provided in a grand clearance region 20A defined on one principal surface of the printed circuit board 20. The strip pattern 21 is connected to a feeding line 29 after extending in a first direction from the connecting point with the capacitive coupling element 10. The strip pattern 22 is connected to a feeding line 30 after extending in a second direction, that is an opposite to the first direction, from the connecting point. The strip pattern 23 is connected to a ground pattern 24 after extending in a third direction from the connecting point. The capacitive coupling element 10 is disposed with an offset toward the first direction. The strip pattern 21 is shorter in length than the strip pattern 22.
