Nuclear fusion has the potential to be a nearly unlimited, safe and CO2-free friendly energy source which would allow coping with the increasing demand in energy consumption, currently heavily based on the fast depleting fossil fuels (over 80%). Fusion devices are ring-shaped metal vessels provided with numerous openings for diagnostic systems and additional heating systems. One of the most important one is the Electron Cyclotron Heating and Current Drive system (ECH&CD), that aims to provide high power (several MW) in the rage of hundreds of GHz into the plasma, a hot gas composed by Deuterium and Tritium nuclei. In this paper we present the possible configurations of ECH&CD systems required by future fusion power plants. The focus will be on launching antenna systems without movable parts close to the plasma (i.e. remote steering concepts and truncated waveguides) and chemical vapor deposition (CVD) diamond windows. The latter are crucial to ensure flexibility in operation of Radio Frequency source (Gyrotrons), when the latter are capable to tune the beam frequency to the desired resonance.
