We present a computationally efficient method for detecting faulty elements in a small linear microstrip patch array from samples of the array's far‐field magnitude radiation pattern (here represented by realistic EM simulations). Regardless of the array size, our method requires only one expensive full‐wave entire‐array simulation—compared to, e.g., the 696 required by the previous best method (Patnaik...
A fast technique for fault detection in realistic, electromagnetic (EM)-simulated antenna arrays is proposed. In our approach, an auxiliary analytical array factor formula is enhanced using suitable response correction methods and utilized as a fast representation (or surrogate) of the accurate, EM-based array model. The surrogate is then used to detect faulty elements from amplitude-only data using...
