Title: Innovations of Yoshihiko Kuwahara
Introduction
Yoshihiko Kuwahara is a notable inventor based in Hamamatsu, Japan. He has made significant contributions to the field of technology, particularly in antenna design and radar systems. With a total of six patents to his name, Kuwahara's work reflects a deep understanding of both theoretical and practical applications in his areas of expertise.
Latest Patents
One of his latest innovations is a directional antenna. This antenna includes a substrate, a power-supply radiating element, paired non-power-supply radiating elements, and a metal plate. The power-supply radiating element is formed on the front surface of the substrate and is aligned vertically. It receives electric power from the power-supplying portion. The paired non-power-supply radiating elements are positioned vertically and oppose each other across the power-supply radiating element in a horizontal direction. A part of the metal plate is located behind a section of the power-supply radiating element, while it is absent behind the paired non-power-supply radiating elements. The 3 dB beam width of this directional antenna on the horizontal plane is equal to or greater than 180 degrees, including the range forward of the antenna.
Another significant patent is a neural network-based radar system. This system features an array antenna with antenna elements that output reception signals in response to one or more arriving waves. The signal processing circuit incorporates a learned neural network. This circuit receives the reception signals, inputs them or a secondary signal generated from them into the neural network, and performs computations using the learned data. The output indicates the number of arriving waves detected by the system.
