Title: Innovations by Kazuro Kato
Introduction
Kazuro Kato is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of antenna technology, holding a total of 3 patents. His work focuses on improving the efficiency and accuracy of antenna systems, particularly in satellite tracking and attitude control.
Latest Patents
Kato's latest patents include an innovative antenna apparatus and an attitude control method. The attitude control method involves detecting the phase difference between signals received by at least two antennas. This allows for the detection of the angle of deflection between the direction of arrival of radio signals and the antenna beams. By utilizing antennas that are separately driven within the plane of rotation, the phase of the received signals can be shifted equivalently to when the antennas are driven as a consolidated unit. Furthermore, when at least three antennas are arranged orthogonally, the antennas can be divided into two groups for individual driving. This design reduces the inertia of moving parts and minimizes the size and weight of the drive mechanisms. Additionally, Kato's method employs two orthogonal functions to represent the phase of the deflection angle, enabling precise control and error elimination.
Another significant patent is his satellite tracking antenna system, which comprises three or four plane antennas arranged on a single plane. The system detects phase differences between signals received by antennas positioned in both azimuth and elevation directions. This allows for accurate determination of the declination of the antenna unit with respect to the satellite. The antenna unit is then driven to minimize these declinations, ensuring optimal tracking performance.
