Open the CIPO recordAbstract From the Canadian patent
A resonator element formed of a half or a quarter of dielectric cylinder contacts an electrically conductive plane via the resonator element's radially cut side which includes the axis of the cylinder and, accordingly, resonates in TE01.delta.-mode. On an opposite side of the electrically conductive plane there is provided an unbalanced transmission line for example, a, strip line type or a coaxial line type. An end of the transmission line is electromagnetically coupled via a dielectric material in the transmission line or directly with the radially cut side of the resonator element through an opening provided on the electrically conductive plane. The coupling circuit according to the …

Why it's free to use
- Filed March 13, 1990 and granted March 29, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 13, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 13, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
