The failure of antenna array elements leads to inaccurate far-field radiation patterns. When failed elements are present in an antenna array used for sensitive applications, it will compromise the measured data, which may severely affect the end-resu

In this work, a machine learning technique is used to detect and locate failed elements in an antenna array. The approach allows for detection and location of up to two simultaneous failures. The far-field pattern is sampled in different ways to form
