Claim 9:
10. The semiconductor package of claim 1, wherein the antenna substrate comprises:
a core layer,
a first wiring layer and a second wiring layer disposed on a lower surface of the core layer and an upper surface of the core layer, respectively,
a plurality of first build-up insulating layers disposed on the lower surface of the core layer,
a plurality of third wiring layers, each disposed on a lower surface of each of the plurality of first build-up insulating layers,
a plurality of second build-up insulating layers disposed on the upper surface of the core layer,
a plurality of fourth wiring layers, each disposed on an upper surface of each of the plurality of second build-up insulating layers,
a first cover layer disposed on the lower surface of a lowermost first build-up insulating layer among the plurality of first build-up insulating layers, and covering at least portions of a lowermost third wiring layer among the plurality of third wiring layers,
a second cover layer disposed on the upper surface of an uppermost second build-up insulating layer among the plurality of second build-up insulating layers, and covering at least portions of an uppermost fourth wiring layer among the plurality of fourth wiring layers,
wherein the core layer is thicker than each of the plurality of first build-up insulating layers and the plurality of second build-up insulating layers.
