Hidetsugu Yagi (八木 秀次, Yagi Hidetsugu; January 28, 1886 – January 19, 1976) was a Japanese electrical engineer from Osaka, Japan. When working at Tohoku Imperial University, he wrote several articles that introduced a new antenna designed by his assistant Shintaro Uda to the English-speaking world. The Yagi-Uda antenna, patented in 1926, allows directional transmission using radio waves, and is especially useful in the very high frequency and ultra high frequency radio bands . Antennas of this type were widely used for television and radio reception, and are still common in communication and radar systems. Yagi also tried, unsuccessfully, to introduce a wireless power transmission system. He participated in establishing the Chiba Institute of Technology. He was the fourth president of Osaka University from February 1946 to December 1946. In 1942, he became the President of Tokyo Institute of Technology, in 1944 he became the President of the Technical Institution, and in 1946 also the President of the Osaka Imperial University.
