The coupling asymmetry characteristics of an ion cyclotron resonance heating (ICRH) antenna consisting of two poloidal aligned straps are studied for a JET‐type tokamak. The model used combines a three‐dimensional (3‐D) planar, cold‐plasma, single pass antenna‐plasma coupling code with any phase difference between the current straps, which takes into account the feeders' current and phase difference effects. The result shows that the asymmetry of radiated energy in poloidal direction can be controlled through changing the phase difference of the antenna straps, and when the phase difference equals to π, the asymmetry tends to become most pronounced (© 2011 WILEY‐VCH Verlag GmbH & Co.
