A semiconductor device package is provided that includes a substrate, a first support structure disposed on the substrate and a first antenna. The first support structure includes a first surface spaced apart from the substrate by a first distance. The first antenna is disposed above the first surface of the first support structure. The first antenna has a first surface, a second surface opposite the first surface and a third surface extending from the first surface to the second surface, wherein the first surface and the second surface of the first antenna are exposed.
