A survey is presented of the microwave transmission system and antenna technology that has been developed for electron cyclotron heating (ECH) experiments using gyrotron and FEL sources. The development of these sources make the bulk heating of a fusion reactor a realistic possibility. Utilization of these sources, with their high unit output power and higher order output modes, has required the development of novel transmission and launching systems. Many examples of such systems applied to tokamaks will be given.
