US Patent 11587916 Package structure and manufacturing method thereof

A package structure includes a semiconductor die, an antenna substrate structure, and a redistribution layer. The semiconductor die is laterally wrapped by a first encapsulant. The antenna substrate structure is disposed over the semiconductor die, wherein the antenna substrate structure includes a circuit substrate and at least one antenna element inlaid in the circuit substrate. The redistribution layer is disposed between the semiconductor die and the antenna substrate structure, wherein the at least one antenna element is electrically connected with the semiconductor die through the circuit substrate and the redistribution layer. The at least one antenna element includes patch antennas.
