Abstract
An integrated fan out (InFO) antenna includes a reflector on a surface of a substrate; and a package. The package includes a redistribution layer (RDL) arranged to form an antenna ground, and a patch antenna over the RDL, wherein the RDL is between the patch antenna and the reflector. The InFO antenna further includes a plurality of connecting elements bonding the package to the reflector. Each connecting element of the plurality of connecting elements is located inside an outer perimeter of the reflector. The InFO antenna is configured to output a signal having a wavelength.
