A novel method for the diagnosis of array antennas is proposed in this paper. The current distribution of the array antennas is reconstructed by the proposed method, which is based on the eigenmode currents over the entire array antennas and its near-field data. The eigenmode currents over the entire array antennas are numerically obtained via the method of moments. Only the dominant eigenmode currents are used for the reconstruction of the current distribution of the array antennas to alleviate the ill-posed nature of an inverse problem. The current distribution of the array antennas is reconstructed using the proposed method, and the optimum parameters for the proposed method, i.e., the number of dominant eigenmode currents and the length of a cylindrical scanning surface, are clarified. Finally, the proposed method is applied to the diagnosis of array antennas with abnormal excitations.
