A Massive MIMO Panel Array at Ka-Band with Flexible Patterns and Beam Steering Performance

In this paper, we are presenting a software defined based massive multiple input multiple output (MIMO) panel array antenna with flexible radiation patterns and beam steering application. This design involves a Ka-band (31.7 GHz to 33.46 GHz) 4 x 4 microstrip patch planar array with dual linear polarizations and good isolation which is required for a massive MIMO antenna system. In this case, by controlling input excitations of the selected radiating elements in the array, we generate radiation patterns with variable beamwidths or directivity at the broadside angle. Further, by applying variable amplitude and phase excitations to the partial or full array, we generate beam steering radiation patterns. Additional analysis and measured performance results will be presented during the conference.
