Abstract: The coupling efficiency of antenna in tokamak for ion cyclotron resonance heating frequency range, depends mainly on the system and size of the antenna. Based on the difference of plasma absorption performance to different spectrum component,and on whether the antenna current spectrum matches the spectrum of plasma absorption, the problem of antenna design of fast wave heating is discussed in detail.

Key words: fast wave heating, resonance absorption, spectrum match
