Keating & Bennett, LLP
Multilayer coil device, antenna module, and wireless communication module
A multilayer coil device includes a multilayer body including first and second coil conductors each having a winding planar shape and a magnetic shield member having a planar shape. Winding regions of the first and second coil conductors partially overlap each other as seen in a direction in which the winding axes extend. The magnetic shield member is between the first and second coil conductors in the direction in which the winding axes extend and overlaps a first region where the first and second coil conductors overlap each other and does not overlap at least a portion of a second region where the first and second coil conductors do not overlap each other.
