I am a radio boy who was born and raised in the famous electronics town Akihabara. I grew up playing here, using my allowance to buy electronic components and building my own radios and amplifiers based on magazine articles. I was licensed my amateur radio station JE1BQE in middle school, and throughout my student years, I spent almost my time building my own radios and antennas, and having communications with my amateur radio friends.
After graduating from the university, I worked primarily in design at automotive and electronics manufacturers, but as I had been wanting to bring my vision of the ideal radio and antenna to life, I founded a wireless communication equipment design company (AMPLET, Inc.) in 1987.
Currently, I work as a consultant on wireless communication technology and antenna design at the AMPLET Communications Laboratory, and I teach a course on "Advanced Science and Technology" at Graduate School of Science and Technology, Nihon University.
I am a very active Ham Radio Operator. My operations are mainly Morse Code Communication (CW) without a PC. I look forward to meeting you on the air.

I invented the Spiral Ring Antenna, and received Doctorate Degree in Electronics Engineering.
The Spiral Ring Antenna which is a small antenna having a toroidal coil shape consisting of a fixed length wire is proposed. The antenna has a size of 1/15 ~ 1/5 wavelength, and this antenna has a relatively high gain (+2.0dBi at 1/10 wavelength), and can easily be matched to a coaxial line without Balun.
