Radiation pattern measurements of geometrically small antennas performed in non-anechoic environments

The dataset contains unprocessed measurements of radiation pattern characteristics performed in non-anechoic regime for three geometrically small antenna structures: a spline-parameterized Vivaldi structure, a compact spline-based monopole, and a quasi-Yagi geometry with enhanced bandwidth. The responses have been obtained over broad frequency ranges (several GHz) 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 Measurement Journal (https://doi.org/10.1016/j.measurement.2023.113705).
