An ANN Application for Fault Finding in Antenna Arrays

A very flexible approach of locating fault elements in antenna arrays is proposed using artificial neural networks (ANN). The network takes samples of radiation pattern of the array with fault elements and maps it to the location of the faulty element in that array. The developed methodology is tested for a linear array and the same can easily be extended for planar arrays also. The developed network can be used at the base stations to find out the number and location of the fault elements in the array in space platforms
