  - IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT - Year 2024

  Power transformers and gas-insulated switchgear (GIS) play crucial roles in electrical power grids. However, they may suffer from degradation of insulation material due to wear and tear, leading to their imminent failure. Partial discharges (PDs) are an initial sign of insulation materials degradation which emit signals spanning various physical domains, including electromagnetic. PDs are temporally narrow, high-frequency, stochastic...

• Transmission measurements between two geometrically small Vivaldi antennas performed in non-anechoic propagation conditions

  Open Research Data

  open access

  • M. Dzwonkowski
  • V. Waladi
  • A. Bekasiewicz

  The dataset contains unprocessed measurements of complex transmission (and reflection) characteristics obtained in non-anechoic regime for a geometrically small, broadband spline-parameterized Vivaldi structure. The measurement setup comprises two Vivaldi antennas with the same topology where one is used as a reference structure, and another one as...

• Measurements of electrically small antenna radiation patterns in non-anechoic environments using TGM

  Open Research Data

  open access

  • A. Bekasiewicz

  The dataset contains raw and processed measurements of radiation pattern characteristics performed in non-anechoic regime for four antenna structures: a spline-parameterized Vivaldi structure, a compact spline-based monopole, super-ultrawideband antenna, and a quasi-Yagi component. The responses have been obtained at the selected frequencies of interest...

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

  Open Research Data

  open access

  • A. Bekasiewicz
  • V. Waladi

  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...

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

  Open Research Data

  open access

  • V. Waladi
  • A. Bekasiewicz

  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...
