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 (20-85MHz). A new concept of the traditional short-circuited strip-line antenna is presented in which a long strap is connected in parallel with a very short section. The latter acts as a matching clement 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 feed-line central conductor. This allows to dispense with the need of a ceramic support in the immediate vicinity of the antenna that will be subjected to a harsh neutron environment in a reactor.
