Latest Patents
Maria Carvalho holds a patent for an impedance-matching coupler. This invention comprises a dielectric substrate onto which a conducting strip is disposed. A dielectric layer, preferably a dielectric film, is formed on top of the conducting strip and the first dielectric layer to encircle the conducting strip. A metallic layer is finally provided on top of the dielectric layer. The dielectric layer has a dielectric constant that is substantially higher than that of the dielectric substrate, preferably more than ten times higher. The dielectric film has a thickness of less than 100 μm, ideally between 5 and 100 μm, and even more preferably between 10 and 70 μm. The thickness of the dielectric substrate is preferably larger than that of the dielectric film, ideally more than ten times larger. The conducting strip has a constant width, and the dielectric film thickness is preferably larger than 10% of the conducting strip width.
