Latest Patents

One of Sakai's latest patents is a non-reciprocal circuit device and communication apparatus. This invention includes a first substrate with a magnetic plate featuring a circular surface and a dielectric ring with an annular surface. The circular and annular surfaces are designed to be substantially coplanar. The device also incorporates a second substrate, a center conductor positioned between the two substrates, and a permanent magnet that applies a magnetic field to the center conductor. The center conductor consists of a main conductor portion aligned along a straight line from the center of the circular surface to the outer periphery of the annular surface, along with a protrusion portion that has a smaller width than the main conductor portion.

Another patent by Sakai describes a similar non-reciprocal circuit device, which includes a substrate with a magnetic plate and a center conductor. This center conductor features a main conductor portion and a branched conductor portion that extends radially from the center of the circular surface. The branched conductor portion has both a wide section on the circular surface and a narrow section that crosses the boundary between the circular and annular surfaces.
