Abstract
A textured dielectric patch antenna is fabricated by applying a first mask pattern () to a first side of a solid panel made of a first material that is a ceramic dielectric and then sandblasting the solid panel through the first mask pattern from the first side to at least partially generate a shaped cavity (). The shaped cavity of the solid panel may be filled with a second material (). The first and second materials have substantially differing dielectric constants. The first side and second side of the solid panel are metallized (), forming a patch antenna. The shaped cavities can be made more complex by using additional masking and/or sandblasting steps.
