Classification: CPC H | IPC H

Claim 10:
11. A package structure, comprising:
a first redistribution circuit structure, having a first side and a second side opposite to the first side along a first direction;
a semiconductor die, disposed over the first side of the first redistribution circuit structure through a conductive connecting material, the conductive connecting material covering a backside and a sidewall of the semiconductor die;
a second redistribution circuit structure, disposed over the semiconductor die;
an insulating encapsulation, laterally encapsulating the semiconductor die and disposed between the first redistribution circuit structure and the second redistribution circuit structure;
at least one waveguide structure, next to and electrically coupled to the semiconductor die, wherein the at least one waveguide structure comprises:
a part of the first redistribution circuit structure;
a part of the second redistribution circuit structure; and
a plurality of first conductive pillars, each connecting to the part of the first redistribution circuit structure and the part of the second redistribution circuit structure;

a plurality of antennas, disposed over the second side of the first redistribution circuit structure, wherein the plurality of antennas are electrically communicated with the semiconductor die through the at least one waveguide structure; and
an encapsulant, disposed between the first redistribution circuit structure and the plurality of antennas.
