A method of fabricating a microwave waveguide component wherein a plurality of joinable thermoplastic members are first formed. The members when joined, com-, prise a microwave waveguide component having an internal surface that is adapted to be plated. The thermoplastic members are then bonded together. Then the internal, surface is plated to form the finished microwave waveguide component. The present method forms microwave components from plated injection molded thermoplastic and, reaction injection molded thermosetting plastics. In particular the plastic components, made using the present invention exhibit comparable electrical performance as measur-, ed by voltage standing wave ration …

Why it's free to use
- Filed May 6, 1993 and granted March 25, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 6, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 6, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
