This invention relates to a method for testing intelligent antenna faults including: setting the TR switches of all antenna channels a receiving mode and that of the correcting channel a transmission mode, in which, the correcting antenna sends down-line signals to judge if the coupled network and feed lines connecting the array elements are normal by the tested emission signal power of the correcting antenna and the receiving signal power of the array element of the antennas, then to detect if the antenna element of the normal test state is disabled, which judges if the power defference of the measured receiving signal and emission signal is less than a throshld value designed by a fixed coupled relation to get the test result of the fault of intelligent antennas.
