Title: Kazuo Matsubara and His Radio Equipment Patent.
Introduction
Kazuo Matsubara is an inventor associated with Sanyo Electric Co., Ltd. His work includes a patent for radio equipment designed to improve wireless performance, particularly when grounding is not available.
Latest Patents
Matsubara is credited with 1 patent, titled “Radio equipment.” The invention uses an antenna and a ground part formed as substrate members, each incorporating a folded copper-foil pattern. When the patterns are configured to a length of λ/4, they can form a pseudo-antenna with an effective length of λ/2. The patent describes an antenna gain of about 2 dB, along with improved radio-wave radiation, noise resistance, and transmission range. This design aims to support stable radio transmission without grounding and to maintain good performance at low transmission output.
Career Highlights
Matsubara’s patent reflects an engineering approach to addressing practical constraints in radio equipment. By integrating folded patterns into the antenna and ground structure, the design seeks to improve performance in conditions that can limit conventional wireless devices.
Collaborations
Matsubara is associated with Sanyo Electric Co., Ltd. His listed coworkers include Shigekazu Kawai and Tsutomu Ishikura.
Conclusion
Kazuo Matsubara’s radio equipment patent focuses on improving wireless performance through a compact antenna-and-ground design, with the goal of enabling reliable communication even under challenging operating conditions.
