Millimeter Wave Dielectric Resonator and Method of Making.

The general object of this invention is to provide a method of making low cost millimeter wave resonators. A more specific object is to provide such a method using an easily machined organic type binder for the dielectric resonator. A specific object of the invention is to provide such a method of making low cost millimeter wave oscillators. It has now been found that the aforementioned objectives can be attained by replacing the metal walled cavities by dielectric resonators made of plastic and heavily loaded with a higher dielectric constant powder of above 3.5. The dielectric resonator so produced is easily machined due to its organic type binder and also has a higher dielectric constant when loaded with a higher dielectric silicon, gallium arsenide, boron nitride, or quartz. The combination of low dielectric constant plastic plus higher dielectric constant material has the property of being easily machinable, while at the same time havng the electromagnetic properties of the refractory higher dielectric constant material.
