A series fed planar microstrip patch array antenna with 1D beam steering for 5G spectrum massive MIMO applications

A 1 dimensional (D) beam steering planar microstrip patch array antenna with through element technology at 28 GHz is designed. The frequency spectrum chosen is one of the Federal Communications Commission (FCC) released 5G bands - 27.5 GHz to 28.35 GHz. The proposed antenna shows good isolation between the antenna ports of the array, flexible radiation patterns and beam steering capabilities. Thus, it can be employed for the multiuser massive multiple input multiple output (MU-MIMO) applications by exploiting the features of digital beamforming technique.
