Title: Takaaki Ooi: Innovator in Antenna and Noise Filter Technology
Introduction
Takaaki Ooi, an accomplished inventor based in Takefu, Japan, holds an impressive portfolio of 13 patents. His innovations primarily focus on advanced antenna coils and noise filter technologies, contributing significantly to modern communication systems.
Latest Patents
Among his latest patents, Takaaki Ooi has developed an innovative antenna coil that includes a wound body featuring a magnetic core, a surrounding bobbin, and a coil wound around the bobbin. This design incorporates a case to house the wound body and foam material positioned in the gap between them. Notably, the foam is compressed by about 45% to 65% when in a non-load state, thus preventing breakage of the magnetic core and making it optimal for use in short-distance communication systems within the LF-band.
Another notable invention is a noise filter that integrates filter components fitted into depressions within a base member. In this design, an input side of a signal-line lead is inserted into a first cylindrical ferrite bead, with an output side in a second ferrite bead. Additionally, a ground lead is connected to a third ferrite bead, with a feedthrough capacitor placed adjacent to the output side of the second bead. A multilayer capacitor further connects the signal-line lead and ground lead, ensuring efficient noise filtering capabilities.
