Dr. Nathan Cohen

Chief Executive Officer

Dr. Nathan Cohen is the founder and technology visionary behind Fractal Antenna Systems, Inc. An accomplished academic and astrophysicist, Dr. Cohen is widely recognized as the “father” of fractal element antenna technology.

Dr. Cohen began his academic career studying under some of the world’s foremost scientists, including Jack Pierce and Irwin Shapiro at Harvard and Frank Drake at Cornell. He has spent three decades as an active radio astronomer, with special emphasis on antenna and array techniques.

In 1988, Dr. Cohen built the world’s first fractal element antenna and, after working to perfect his methodology, founded Fractal Antenna in 1995 to commercialize his research. He has since become recognized as one of the world’s most innovative antenna designers, with fractal element antennas proving to be far more compact, versatile and powerful than traditional antenna designs.

Dr. Cohen holds a bachelor’s degree in physics from Brandeis University, and a master’s degree and Ph.D. in astrophysics from Cornell University. He retired as a professor from Boston University in 2002. He is the inventor on over two dozen patents to date; has published over 80 articles, and two books. His innovation has been widely recognized in Scientific American; Discover; CNN; Business Week; Wireless Week; and many other publications. He is widely sought as a speaker at technical and business conferences.
