Abstract
A device and method for making a capacitor and other high frequency and/or microwave components. In particular, an air dielectric capacitor has a first electrode and a second electrode that are spaced apart, planar and each of a different size or area. The first electrode is a smaller, planar electrode that is sealed along its edge with a sealant having a constant dielectric to the second electrode, a larger planar electrode. The dielectric constant of the sealant along the edges of the first electrode is substantially uniform. In addition, an epoxy cover extends around the periphery of the smaller first electrode and is supported along the surface of the larger second electrode.
Claims8
A method for making a device comprising:
- separating a first electrode and second electrode with spacers to establish a predetermined spacing d between said electrodes;
- applying a sealant to a plurality of opposite edges of said first electrode to fix spacing between the first electrode and second electrode provide by said spacers;
- removing said spacers once said first electrode and second electrode are fixed with respect to each other;
- sealing the remaining plurality of edges of the first electrode to said second electrode with said sealant such that said space d and common area A between the first electrode and second electrode remains free from contamination;
- and
- forming an epoxy cover around the periphery of the first electrode and above an exposed surface of the second electrode.
A method for making a device comprising:
