Abstract
A dielectric sheet (500, 600, 1621) includes a photodielectric support layer (505, 1630) that may be glass reinforced and a dielectric laminate (510, 605). The dielectric laminate includes first and second metal foil layers (415, 660; 210, 665, 1605, 1610), and a dielectric layer (405, 655, 1620) disposed between the first and second metal foil layers. The first metal foil layer is adhered to the photodielectric support layer. In a printed circuit and patch antenna that includes the dielectric sheet, the first metal layer is patterned by removal of metal according to a circuit pattern and the photodielectric support layer is patterned by removal of dielectric material according to the circuit pattern.
