Abstract :
An algorithm has been used to detect defective elements errors in array antennas. It has been applied to an X band slot array antenna and good results have been obtained. These have enabled the detection of errors in the manufacture process. We have used spherical near field measurements of the radiated field of the antenna. Then, once the equivalent currents are be obtained, an analysis of these results will be made in order to detect possible mistakes.
