Efficient analysis of arrays of compact metallic elements devoted to satellite SAR
conference paper
A fully metallic monopole element is proposed for satellite SAR antennas. This element has significant gain in the broadside direction thanks to its curved arm. This element is then studied in a large sparse array. A fast analysis technique is presented in order to solve for the currents of few hundreds elements, which correspond approximately to one millon basis functions. This method is based on macro basis functions coupled with an iterative solver accelerated with a multipole decomposion. This combination reduces drastically the memory requirements and shrinks the execution time. Good comparison between the proposed method and a commercial software solution is provided. © 2019 European Association on Antennas and Propagation.
