mmWave Beamforming systems

User and Vehicle Blockage of mmWave Beamforming Systems

Researchers from Qualcomm, Amazon, and collaborators focused on understanding the signal-disrupting effects as millimeter waves pass through vehicles and the human hand and body. Measurements with a 28-GHz prototype and simulation studies suggested models of these effects. Analysis showed that disruptions stem from physical movements at time scales of a few 100 ms or more, which can be compensated for via network densification, subarray switching in user equipment, and fallback mechanisms.

Low-Leakage

Low-Leakage, Digitally Modulated mmWave Phased Array

A new method for suppressing undesired spatial leakage of phased arrays is uses antenna elements with digitally modulated quadrature phase shift keying (QPSK) and on-off keying (OOK) elements Fine-grain magnitude and phase control is not required. Simulation and tests show that the leakage power can be suppressed to -25 dBc for most zenith angles between 10º and 50º.
