This article presents a thorough study of spherical probe-corrected phaseless near-field measurements with the two-scans technique. Such technique is based on retrieving the antenna under test radiation pattern from the measurement of the near-field

Fast Spherical Near-Field to Far-Field Transformation for Offset-Mounted Antenna Measurements

Autor: Manuel Sierra Castañer, Belen Galocha Iraguen, Fernando Rodriguez Varela

In spherical near-field measurements, the number of measured samples grows with the radius of the minimum sphere enclosing the antenna under test (AUT). This leads to unnecessary long acquisition times for antennas mounted in offset positions with re

Publikováno v: IEEE Transactions on Antennas and Propagation. 68:7571-7579

This article investigates on the use of nonuniform fast Fourier transform (NUFFT) to solve spherical near-field transformation problems. Traditional postprocessing algorithms make use of conventional FFT for the transformation of measured grids with

Under-Sampled Spherical Near-Field Antenna Measurements With Error Estimation

Autor: Belen Galocha Iraguen, Fernando Rodriguez Varela, Manuel Sierra-Castaner

Publikováno v: IEEE Transactions on Antennas and Propagation. 68:6364-6371

This article proposes an under-sampling scheme in $\boldsymbol {\varphi }$ for spherical near-field antenna measurements. Reducing the number of samples along one of the spherical coordinates allows to decrease the number of positioner steps. Therefo
