MILLIMETER WAVE DIELECTRIC RESONATOR AND METHOD OF MAKING

摘要

Low cost millimeter wave dielectric resonators are made by imbedding a two terminal negative resistance device in a plastic waveguide loaded with a high dielectric constant material. The material of the waveguide may be polytetraflouroethylene, polyethylene, styrene copolymer, epoxy resin or acrylic resin. The high dielectric constant material may be aluminum oxide, silicon, gallium arsenide, boron nitride or quartz. The waveguide is easily machinable, has a high dielectric constant and is much less expensive than a metal walled cavity.
