A dual polarization massive MIMO panel array antenna at Ka-band with beamforming capability

In this paper, we are presenting a dual polarization massive multiple input multiple output (MIMO) panel array antenna with beam steering capability. This design includes a Ka band (31.8 GHz to 33.46 GHz) 4×8 microstrip patch planar array with good isolation between the polarizations which is a desired parameter for a massive MIMO antenna systems. We are controlling input excitations and phases of the individual radiating elements in an array to generate adaptive beamforming characteristics which includes variable gain radiation patterns and beam steering performance. This can be implemented using digital beam forming (DBF) or software defined radio (SDR) technique.
