Abstract
An antenna package according to an exemplary embodiment of the present invention includes a first antenna device which includes a first antenna unit including a first radiator, a second antenna device which includes a second antenna unit including a second radiator whose polarization direction is perpendicular to the first radiator, a first circuit board electrically connected with the first antenna unit, a second circuit board electrically connected with the second antenna unit, and a third circuit board on which at least one antenna driving integrated circuit (IC) chip electrically and independently connected to the first circuit board and the second circuit board is mounted. By supplying power to two antenna devices having different polarization directions, respectively, signal interference and signal loss may be prevented, and dual polarization may be implemented.
