Abstract

Abstract

For the analysis problem of large antenna arrays with radomes, based on the equivalence principle and mode matching theory, the wave port model of Multilevel Fast Multipole Algorithm (MLFMA) is established, and the accurate electromagnetic modeling of antenna excitation source and matching load is realized. Moreover, a parallel strategy of MLFMA for calculating metal-dielectric antenna models is proposed. By establishing multiple octree structures, the communication in processes during the calculation is reduced, and the accurate and efficient analysis of large antenna-array-and-radome-integration system is realized. A comparison of the antenna pattern and S parameters calculated by the proposed algorithm, the higher order method of moments and the finite element-boundary integral is given, validating accuracy and efficiency of the proposed method.
