Title: **The Innovative Contributions of Inventor Takeshi Kijima**
Introduction
Takeshi Kijima is a notable inventor based in Tokyo, Japan. With an impressive portfolio of six patents, he has made significant contributions to the field of electronics, particularly in the development of advanced communication technologies.
Latest Patents
Kijima's latest innovations include a **Multilayer Balun** and a **Directional Coupler**. The Multilayer Balun features a unique design, comprising first to fourth lines and a stack. This invention incorporates a plurality of first conductor layers forming the first and third lines, strategically positioned in a first region within the stack. Additionally, second conductor layers for the second and fourth lines are organized in a second region, with a ground conductor layer placed closer to the second region. A significant aspect of this balun is the inclusion of a conductor layer pair, where the distance between the two layers is minimized.
The Directional Coupler introduced by Kijima includes multiple ports and a main line that connects the first and second ports. It is designed with a first and a second subline section, which are electromagnetically coupled to the main line, and also incorporates a phase shifter. The integration of these components allows for a unique arrangement where the phase shifter outputs a signal that is phase-delayed in relation to the input signal, with the delay amount increasing as the frequency of the input signal rises. Notably, a frequency that is twice as high as the input signal frequency, which provides a 90-degree phase delay, is lower than the frequency at which a 180-degree phase delay is observed.
