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.

Abstract: Disclosed herein is an antenna device that includes a filter layer, an antenna layer, a divider layer, and ground patterns. The antenna layer has first and second radiation conductors and first and second ground pillars that surround the first and second radiation conductors, respectively. Each of the first and second ground patterns has a first area that overlaps a first space surrounded by the first ground pillars, a second area that overlaps a second space surrounded by the plurality of second ground pillars, and a third area that connects the first and second areas. A width of the third area in a width direction perpendicular to an arrangement direction of the first and second areas is smaller than a width of each of the first and second areas in the width direction.
