Correction of far-field measurements obtained in non-anechoic test site

The dataset contains raw and processed measurements of radiation pattern characteristics performed in non-anechoic regime for two geometrically small antenna structures: a spline-parameterized Vivaldi structure and a compact spline-based monopole. The responses have been obtained at the selected frequencies of interest as a function of mentioned structures rotation angle. The latter is understood as angular position of the antenna under test (i.e., one of the mentioned structures) w.r.t. the reference antenna (here, for all experiments, a Vivaldi structure has been used) in a selected plane of rotation. The dataset is supplemented with the models of the antennas used for measurements, as well as a schematic diagram of the non-anechoic test site. The measurements represent a part of the data used for post-processing in the paper published in IEEE Access Journal (https://doi.org/10.1109/ACCESS.2023.3268116).
