Shintaro Uda (宇田 新太郎 Uda Shintarō, June 1, 1896 - August 18, 1976) Japanese inventor. Assistant professor (equivalent position) under professor Hidetsugu Yagi at Tohoku University, where they invented the Yagi-Uda antenna in 1926. 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.
