Antenna substrate

An antenna substrate comprising:

• a body including a plurality of insulating layers stacked in a stacking direction;
• a first antenna layer including a plurality of first pattern layers disposed on the plurality of insulating layers, respectively, and a plurality of first conductive via layers respectively penetrating through the plurality of insulating layers to connect the plurality of first pattern layers in the stacking direction, each of the plurality of first conductive via layers having a bar shape of which a length in a horizontal direction perpendicular to the stacking direction is larger than a length in a width direction perpendicular to the stacking direction and the horizontal direction;
• and
• a second antenna layer extending in at least one of an uppermost portion or a lowermost portion of the first antenna layer on the insulating layers of the body, wherein each first pattern layer has a length larger than each first conductive via layer in the horizontal direction and the width direction in which the second antenna layer extends.

• wherein the plurality of first pattern layers are connected to each other via the plurality of first conductive via layers in all of cross-sections of the first antenna layer that is cut in the stacking direction and a horizontal direction along a width direction in which the second antenna layer extends, the horizontal direction being perpendicular to the stacking direction and the width direction.
