In this paper, a 3D beamforming phased array with 2D stacked tunable Nolen matrix is presented. The fundamental building block - tunable Nolen matrix is proposed to relax phase tuning range of phased ...

A new multilevel Green's function interpolation method (MLGFIM) used for the analysis of microstrip antenna arrays is presented. Dyadic Green's function for a layered medium is used in this method as ...
