Title: Yoshihide Yamada and His Aperture Antenna Patent.
Introduction
Yoshihide Yamada is an inventor associated with Yokosuka, Japan, and Nippon Telegraph and Telephone Public Corporation. His patent work includes an antenna design intended to improve the phase performance of radiated co- and cross-polarization.
Latest Patents
Yamada is associated with 1 patent: “Aperture Antenna Having the Improved Cross-Polarization Performance.” The invention uses a horn to radiate an electromagnetic wave and a focusing element, implemented as either a reflector or a dielectric lens. The focusing element is designed to produce a specified phase distribution across its aperture plane, with the aim of improving the phase performance of both co-polarized and cross-polarized radiation.
Career Highlights
Yamada’s documented patent contribution concerns antenna design and electromagnetic-wave focusing. The patent describes a phase-distribution approach for shaping the field across an aperture.
Collaborations
Yamada’s listed coworkers include Takashi Yamada and Tadashi Takano. The available information identifies them as colleagues but does not specify their roles in the patent.
Conclusion
Yoshihide Yamada’s recorded invention focuses on improving aperture-antenna polarization performance through carefully designed phase distribution.
