Title:
METALIZATION OF POLYMERIC CAVITY FILTERS
Document Type and Number:
WIPO Patent Application WO/2014/086844
Kind Code:
A3
Abstract:
A method for application of a metal on a cavity filter comprising contacting at least a part of said cavity filter base with a mixture, and inducing a polymerization reaction by exposure to at least one selected from heat and actinic radiation adapted to said at least one initiator to form polymers on at least the inner surface of said cavity filter base, said polymers comprising at least one charged group, and said polymers forming covalent bonds after reaction with at least one selected from an abstractable hydrogen atom and an unsaturation on said cavity filter base, and subsequently applying further metal. Advantages of the invention include that cavity filters can be metalized with superior adhesion and giving performance enhancement of the cavity filter compared to existing alumina cavity filters.
