ABSTRACT:
A resistively terminated antenna and method of fabricating a resistively terminated antenna comprising providing a resistor-conductor laminate, selectively removing portions of the resistive and conductive layers to produce an antenna design and mounting the resistor-conductor laminate on the dielectric substrate. Etching selectively removes portions of the conductive and resistive layers, and mounting is accomplished using a spacer, film resistor, and ground plane, where the resistor-conductor laminate is fixed to the surface of the dielectric substrate opposite the film resistor. The film resistor may have a central aperture.
