mmWave multibeam phased array antenna for 5G applications

S. Prasad et al.

Summary: This study presents a fully integrated 28 GHz, 5G mmWave microstrip phased array antenna on a multilayer substrate, providing independently steerable multiple beams and utilizing a computation method to generate these beams. The impacts of hardware impairments on the performance of the array are analyzed through simulation and measurements, with results comparing measurements and simulations for single, dual, and multiple beams over arbitrary angles. The proposed multibeam computation method is validated through measurements at 28 GHz for dual beam cases with equal and unequal power beams and a side lobe level of better than 17 dB.
