[en] The structure of the straps on new type of ICRH antenna for EAST tokamak was introduced. Based on the calculation of the condition in which straps would work, the work temperature distribution of the straps could be obtained. Using this result, the straps resistance to thermal load and its influent on the strap structure under the operation condition are simulated. It is demonstrated that the radiation surface temperature and overall structure strength of the straps under the real thermal load (0.2 MW) satisfy the design requirements. (authors)
