Latest Patents
Katayama's latest patents include a thin-film multilayered electrode and a high-frequency resonator. The first patent describes an inexpensive and reliable thin-film multilayered electrode that can be formed on a dielectric substrate, such as a ceramic substrate. This innovation features thin-film conductors and dielectrics that are alternately layered to achieve a predetermined dielectric constant. The design ensures that the electromagnetic fields created in the dielectric substrate and the thin-film dielectrics are substantially in phase at a specific frequency. The film thickness of the dielectrics ranges from 0.2 µm to 2 µm, while the conductors are thinner than the skin depth at the predetermined frequency.
The second patent focuses on a thin-film multilayered electrode of a high-frequency electromagnetic field coupled type. This invention comprises thin-film conductors and dielectric thin films that are alternately stacked on a dielectric substrate. The film thickness of the dielectric thin films is set to ensure that the phase velocities of TEM waves propagating through the transmission lines are substantially equal. Additionally, the thin-film conductors include an adhesive layer that provides strong adhesion at the interfaces.
