A low cost substrate material is reported using a polypropylene and nano-clay powder composite. The material characteristics, such as dielectric constant, loss tangent, lamination and thermalproperties have been determined. A patch antenna has beenfabricated using the developed substrate material and its performance has been characterized.
IntroductionPatch antennas are used in mobile communications and, broadband wireless access, where product cost, process yield and manufacturability are critical parameters.
