140GHz Two-Dimensional 8×8 Phased Arrays for 6G MIMO Systems
We present the first 140GHz 8×8 phased array with two-dimensional/on-grid scanning capabilities, built using 45RFSOI. The array achieves unprecedented integration levels at 140GHz and shows that phased arrays can be built well at >100GHz using high volume commercial processes including low-cost laminates. RFIC design, system design and measurements will be presented.
