Abstract
A method of forming an antenna reflector having a predetermined curved surface by forcing a plate of metal or plastic upon an array of die members of different heights protruding from a die base, for example, coaxially arranged cylinders of proper height with proper spacing on the die base. This process makes the manufacture of the antenna reflector extremely rapid and easy.
