More Information
Summary:The present invention provides a low cost microstrip line with low loss and a microwave device using the microstrip line. The microstrip line comprises (a) a dielectric substrate for general purpose use with relatively high loss in a microwave frequency, (b) a strip conductor foil disposed on the front surface of the substrate, (c) a metal plate for grounding disposed in contact with the back of the dielectric substrate, and (d) an air layer formed on a portion of the metal plate for grounding, the portion facing to the strip conductor foil.
