George Harold Brown

George Harold Brown ( born October 14, 1908 in Milwaukee, † 11 December 1987 in Princeton ( New Jersey)) was an American electrical engineer.

Life

George Harold Brown's father, a worker on the railroad, was of Scottish descent, while his mother's family came from Germany. After attending high school in Portage (Wisconsin ), where he already experimented with crystal detectors, he studied at the University of Wisconsin -Madison and earned in 1930 his Bachelor of Science in 1931 his master's degree and in 1933 his Ph.D. for his work on radio antennas.

Brown then went to RCA in Camden (New Jersey), where he conducted research on AM radio antenna that has been a worldwide standard.

In 1936, Brown was commissioned to build an omnidirectional antenna, and developed the Turnstile Antenna ( turnstile antenna, because it looks like a turnstile, turnstile ). It provided a high gain and wide bandwidth, making it possible to transmit FM and TV signals on large distances. A later added absorption resistance increased bandwidth and allowed the radiation of TV images and sound from the same antenna.

In 1936 he developed his Vestigial side band filter (see vestigial sideband modulation).

In 1942, Brown went to the new research laboratory of the RCA, where he developed radio and radar antennas for the military.

He and his colleagues developed a method for the production of penicillin to speed by heating with RF radiation.
