Antenna radiation patterns derived from phaseless measurements performed in uncontrolled indoor environments

The dataset contains unprocessed measurements of radiation pattern characteristics performed within a non-anechoic regime for a spline-parameterized Vivaldi structure. The responses have been obtained for two configurations concerning distributed spatially-distinct positions of the measurement gear (also referred to as setups), as well as for its distribution along a line. Measurements are performed over a broad frequency ranges (several GHz) as a function of rotation angle. The latter is understood as angular position of the antenna under test w.r.t. the reference antenna (here, for all experiments, a Vivaldi structure is used as both) in a selected plane of rotation. The dataset is supplemented with the antenna model, as well as a schematic diagram of the non-anechoic test site configuration with highlight on utilized setups. The measurements represent a part of the data used for post-processing in the paper published in IEEE Antennas and Wireless Propagation Letters (https://doi.org/10.1109/LAWP.2025.3596814).
