Effects of inter element spacing on large antenna array characteristics

Large-scale antenna arrays have been the current interest in the study of massive MIMO as a promising technology for 5G. Planar arrays have become the suitable antenna array configurations for massive MIMO since they provide directive beams. In this paper, planar array is proposed with square and re...
