Open the CIPO recordAbstract From the Canadian patent
A planar dielectric integrated circuit is provided such that energy conversion loss between a planar dielectric line and electronic components is small and that impedance matching between them can be easily obtained. A planar dielectric line is provided by causing two slots to oppose each other with a dielectric plate interposed in between a slot line and, line-conversion conductor patterns are provided in the end portions of the planar dielectric line and an FET is disposed, in such a manner as to be extended over the slot line.

Why it's free to use
- Filed February 25, 1998 and granted September 25, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 25, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 25, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
