Efficient analysis and design of finite phased arrays of printed dipoles using fast algorithm: Some case studies

Abstract

This paper presents an accurate and efficient method of moments (MoM) analysis for characterizing a large-scaled phased dipole array. In this method, the mixed potential integral equation (MPIE) is utilized and solved iteratively using the generalized conjugate residual method. The precorrected fast Fourier transform (pFFT) method is employed to accelerate the entire computational process so as to reduce significantly both the memory requirement and the computational time for designing large arrays. Numerical results of an example, which had to be solved using approximate approach due to the large number of elements, are presented to demonstrate the efficiency and accuracy of the present method. © 2007 VSP.
