1. An antenna package, comprising:
an antenna device comprising:
a dielectric layer;
a first antenna unit arranged on the dielectric layer;
a second antenna unit arranged on the dielectric layer to be physically and electrically separated from the first antenna unit; and
an antenna ground layer disposed on a bottom surface of the dielectric layer; and
a printed circuit board coupled to the antenna device to be electrically connected to the first antenna unit, and electrically separated from the second antenna unit,
wherein the first antenna unit comprises a first radiator, a first transmission line extending from the first radiator and a first signal pad connected to one end portion of the first transmission line,
the first radiator, the first transmission line and the first signal pad are disposed at the same layer,
the second antenna unit comprises a second radiator, a second transmission line extending from the second radiator and a second signal pad connected to one end portion of the second transmission line,
the second radiator, the second transmission line and the second signal pad are disposed at the same layer, and
the antenna ground layer overlaps the first radiator and the second radiator in a planar view, and does not overlap the first signal pad and the second signal pad in the planar view.
