Shintaro Uda

Shintaro Uda (宇田新太郎, Uda Shintarō, June 1, 1896 – August 18, 1976) was a Japanese inventor, and assistant professor to Hidetsugu Yagi at Tohoku University, where together they invented the Yagi–Uda antenna in 1926.

Yagi-Uda antenna design for communication at a wavelength of λ.

In February 1926, Yagi and Uda published their first report on the wave projector antenna in a Japanese publication.[1] Yagi applied for patents on the new antenna both in Japan and the United States. His U.S. Patent 1,860,123 ("Variable Directional Electric Wave Generating Device") was issued in May 1932 and assigned to the Radio Corporation of America.
