Abstract
Disclosed are patch antennas, systems and methods for embedding a patch antenna between two layers, such as two layers of glass. The glass layers may be a vehicle windshield. An embedded portion of an antenna substrate supporting the patch antenna may be embedded between the two layers, and an exposed portion of the antenna substrate may extend outward from the two layers. The embedded portion of the antenna substrate may support the patch antenna, and the exposed portion of the antenna substrate may support a coplanar waveguide and a connector.
