Optimization of planar subarray structure based on random search method for large active electronically scanned array antenna

Abstract

In this paper, the planar subarray structure to be optimized by using random search method for large active array antenna is presented. Although MPSL of the optimized subarray structure is 1.09 dB higher, G/T of the optimized subarray structure is 2.07 dB higher than the reference subarray structure.
