Polarimetric analysis of mm-wave propagation for advanced beamforming applications

Pencil-beam forming techniques based on large antenna arrays are becoming a crucial asset to cope with the very high throughput density requirements and high path-loss constraints of future millimeter-wave gigabit-wireless applications. Directional, polarimetric 60 GHz indoor measurements are used in the present work to modify and calibrate a 3D ray tracing model and in particular to tune the embedded effective-roughness diffuse scattering model. The potential of polarimetric beamforming is then evaluated through system simulation in simple, reference cases using the ray tracing model as a propagation-prediction engine.
