UWB Tightly Coupled Array Optimization and Design of Unequal Power Divider

In order to meet the requirements of ultra-wideband (UWB), low peak side lobe level (PSLL) and high gain of tightly coupled array antennas, this paper adopts the covariance matrix adaptive ES algorithm based on MOEA/D (MOEA/D-CMA-ES) to optimize the interval of different elements, and uses the aggressive space mapping (ASM) algorithm compensates for the coupling between the array elements, and finally a 1:32 ultra-wideband unequal power divider is designed as the feeder network.
