A Study of a Probe-Based Millimeter-Wave Far-Field Antenna Measurement Setup [Measurements Corner]

This article presents a finite difference time domain (FDTD) analysis of a probe-based millimeter-wave (mm-wave) far-field antenna measurement setup. First, it is found that a full-wave simulation of the entire setup requires formidable computational resources, and thus a reasonable simplification of the setup model is made. Then, an electric dipole antenna operating at 28 GHz is placed in the setup, and the reflected/scattered/refracted/absorbed/diffracted/obstructed field distribution and distortion on radiation patterns by equipment are simulated. Finally, a quiet zone assessment is conducted.
