Victor H. Rumsey

Dr. Victor H. Rumsey (November 22, ? - ) is an electrical engineer, best known for his studies of frequency-independent antennas.

Rumsey was born in Devizes, Wiltshire, England, on Saint Cecilia's day, and received his BA in mathematics (1941) and Sc.D. in physics from Cambridge University. From 1941-1945 he performed radar research at the Telecommunications Research Establishment in England and the Naval Research Laboratory, Washington, DC. After three years at the Canadian Atomic Research Laboratory he became director of the Antenna Laboratory at Ohio State University. In 1954 he moved to the University of Illinois, in 1957 to the University of California, Berkeley, and in 1966 to the University of California, San Diego where he is now Professor Emeritus.

Starting in the 1950s, Rumsey suggested basic principles for developing frequency-independent antennas. In 1999, Nathan Cohen showed that these principles were incomplete, and later article by Robert Hohlfeld and Cohen proved that self-similarity was required, i.e., a fractal antenna. Conditions for frequency invariance are called now "Hohlfeld-Cohen-Rumsey" (HCR) conditions.

Rumsey is a member of the National Academy of Engineering, and has received an honorary Doctor of Engineering degree from Tohoku University, Japan, the 1962 IEEE Morris N. Liebmann Memorial Award, and the 2004 John Kraus Antenna Award.
