During this time he developed early forms of the chart which was later to become generally known as the “Smith Chart. ” From 1935 to the outbreak of World War II, Mr. Smith was engaged in the design of directional antenna equipment for commercial AM radio broadcasting, During the war his experience with directional antennas was utilized in the design and development of RADARantennas where his numerous contributions placed him on the Reserved List of War Manpower Commiss~on’s Committee of Scientific and Research Personnel. Following the war, Mr. Smith turned his attention to commercial FM radio broadcasting antenna design and subsequently invented the “Cloverleaf’t antenna. More recently he has been involved in Military weapon systems studies and design, and has supervised groups responsible for the electrical design of the DEWline, SAGE systems, NIKE-ZEUS, and NIKE-X radar antennas.
