Direction-of-Arrival (DOA) estimation capability of sensor arrays is greatly influenced by geometric configuration of arrays. We proposed a new type 2-D planar array, improved Archimedean spiral array ...

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 ...
