Zitat:
Beginning their work in 1924, Professor Hidetsugu Yagi and his assistant, Shintaro Uda, designed and constructed an antenna which was sensitive and highly-directional. It utilized a driven element with closely-coupled parasitic elements which made it effective in the higher-frequency ranges. Therefore, it has been important for radar, television, and amateur radio. Yagi speer-headed the research effort and Uda published the English version of the work so both
scientists take credit for its development, but this antenna is better known as the Yagi antenna.

Herr Yagi erhielt dafür auch 1932 ein Patent in den USA.
