An antenna substrate includes: a first insulating layer surrounding a cavity; a second insulating layer of which at least a portion is disposed in the cavity and containing an insulating material different from an insulating material of the first insulating layer; a first patch antenna having one surface facing the first insulating layer by an amount greater than half of an area of the first patch antenna; and a second patch antenna having one surface facing the cavity by an amount greater than half of an area of the second patch antenna.

Antenna substrate and electronic device including the same

An antenna substrate includes a body in which a plurality of insulating layers are stacked, a first antenna layer including a plurality of first pattern layers disposed on the plurality of insulating layers and a plurality of first conductive via layer penetrating through the plurality of insulating layers to connect the plurality of first pattern layers in a stacking direction of the plurality of insulating layers and having a bar shape, and a second antenna layer extending from at least one of an uppermost portion or a lowermost portion of the first antenna layer on the insulating layer of the body.

Antenna substrate

An antenna substrate includes: a body having a first surface and a second surface opposing each other and a side surface connecting the first surface and the second surface to each other; an antenna portion disposed on the first surface of the body; and a pad portion disposed in the body, exposed to the side surface of the body, and including a plurality of pad layers connected to each other in a first direction from the second surface of the body toward the first surface of the body. At least one of the plurality of pad layers has a greater width in a second direction than in a third direction perpendicular to the second direction when viewed in the first direction.

An antenna substrate includes a body including an insulating material, a plurality of wiring layers stacked with each other in a first vertical direction in the body, and a plurality of first antenna layers stacked with each other in a third horizontal direction in the body. Each of the plurality of first antenna layers includes a plurality of conductive structures, each having a length in a second horizontal direction greater than a length in the third horizontal direction perpendicular to the second horizontal direction, that are stacked in the first vertical direction.

A printed circuit board includes a core layer having a first surface and a second surface opposing the first surface; a first built-up structure disposed on the first surface of the core layer; a second built-up structure disposed on the second surface of the core layer; and a first penetration portion penetrating the first built-up structure and the core layer and penetrating a portion of the second built-up structure. The first penetration portion has a step portion on at least a portion of a wall of the first penetration portion in the region of the first penetration portion penetrating the second built-up structure, and a region including the first penetration portion on a plane is configured as a flexible region.
