Shintaro Uda assisted Hidetsugu Yagi with the invention of a wireless antenna that would prove to be valuable as a radar antenna and a television receiver.

Yagi was an engineering professor at Tohoku Imperial University who had trained with European and American scientists. He and Uda developed an antenna for receiving ultrashort waves, publishing their first report in 1926 and receiving patents in Japan and the United States (Number 1,860,123).

This technology was not widely received in Japan, but became prevalent among the Allies, who depended on these antennas for radar during World War II. After the war, this antenna was used to receive television signals.
