Abstract: A composite electronic component includes a multilayer stack, a filter, and an antenna. The filter is located within the multilayer stack and interposed between a first ground conductor layer and a second ground conductor layer. The antenna includes a radiation element. The radiation element is located on a side of the second ground conductor layer opposite from the first ground conductor layer. When viewed in a direction parallel to the stacking direction of the multilayer stack, the radiation element entirely lies inside the perimeter of the second ground conductor layer. The multilayer stack includes a plurality of connection conductor sections arranged around the filter and connecting the first ground conductor layer and the second ground conductor layer.

Abstract: Disclosed herein is an antenna device that includes: a substrate having a plurality of insulating layers laminated in a z-direction; a first ground pattern formed on a first insulating layer; a first radiating conductor pattern formed on a second insulating layer; a second ground pattern constituted by a first via conductor provided so as to penetrate at least two insulating layers; and a second radiating conductor pattern constituted by a second via conductor provided so as to penetrate at least one insulating layer. The first radiating conductor pattern overlaps the first ground pattern in the z-direction. The second radiating conductor pattern overlaps the second ground pattern in a y-direction.
