Abstract
A microwave antenna and receiver assembly is described for use at gigaherz frequencies wherein the antenna is a microstrip antenna and the receiver includes a stripline filter circuit which is integrated in a layered configuration with both the microstrip antenna and the amplifier so as to achieve a very low noise figure, a low SWR and preserve good receiver characteristics, while being easily assembled inside a common radome housing. An inexpensive substrate material formed of alternating layers of polypropylene and woven glass is described for use with the microstrip antenna and other microwave structures.
