The flexibility provided by a variety of ion cyclotron resonance heating (ICRH) and current drive (CD) scenarios for ITER requires that the antenna should operate at a number of frequencies spread over a wide frequency range (20-85 MHz). A short circuited strip-line antenna in which a long strap is connected in parallel with a very short section is shown to provide the frequency range of operation required for ITER. The short section acts as a matching element located within the antenna and improves the power coupling capability especially at low frequencies where the plasma coupling is generally poor. The short section also supports the feeder-line central conductor. This means there is no longer a need for a ceramic support in the immediate vicinity of the antenna that will be subjected to a harsh neutron environment in a reactor
