ABSTRACT:
Method and structure are disclosed for production of a thick-film antenna. A thick-film microwave patch element (26) is patterned onto one surface of a dielectric substrate (32) and a thick-film reference surface (24) disposed onto the opposite surface. The patch element may be placed in different locations on the substrate relative to the feed hole to adjust the impedance and resonant frequency of the antenna before it has been dried and fired while tuning tabs (30) may abut the patch element for use in adjusting the impedance and resonant frequency of the antenna (20) after it has been dried and fired. In one embodiment, the substrate (24) is a ceramic material having an alumina content of about 96%. A multiple-frequency antenna can be created by stacking patch elements and dielectric layers above the reference surface.
