mm-Wave Experimental Scanning System to Determine the Complete Field by Near-to-Near Field and Near-to-Far Field Transformation

A novel measurement system and a 3D field reconstruction method with near-to-near field and near-to-far field forward transformation are described for wireless transmitters operating at frequencies from 6 – 110 GHz. Measurements are taken as close as $\lambda /6$ and the reconstructed 3D field distributions are compared against simulated results. The uncertainty in the measurement plane is better than 1.4 dB. The uncertainty budget at arbitrary observation points will be developed and validated by simulations and far-field measurement systems.
