  • A. Rydlewska
  • W. Zieniutycz

  - Rok 2012

  The UWB monopole antenna with elliptical radiating slot end and microstrip feeding line terminated with radial stub have been designed, fabricated and measured. The antenna show return loss less than -12 dB in the whole UWB bandwidth. Linearity of the reflection coefficient phase product have also been achieved. Radiation patterns of the antenna measured at three selected frequency points indicated regular, approximately omni directional...

  - Rok 2019

  The article presents four concepts of the multi-zone voltage regulation (MZVR) system. It is a combination of a distribution transformer with an on-load tap-changer, for step voltage regulation, and a power electronic converter, dimensioned for a fraction of MZVR power, realizing continuous voltage regulation, supplemented by a special switch, the so-called bypass. This allows voltage regulation at high resolution, wide range and...

• Fast geometry scaling of UWB band-notch antennas

  Publikacja

  • S. Kozieł
  • A. Bekasiewicz

  - Rok 2016

  Implementation of band-notch capability plays an important role in the design of ultra-wideband (UWB) antennas. At the same time, appropriate sizing of antenna geometry parameters in order to precisely allocate the notch at the required frequency as well as to ensure sufficient reflection level is quite challenging and has to be based—for reliability reasons—on full-wave electromagnetic (EM) simulations of the structure. In this...

• Rapid dimension scaling of compact microwave couplers with power split correction

  Publikacja

  • S. Kozieł
  • A. Bekasiewicz
  • J. Bandler

  - Rok 2017

  In this paper, a technique for rapid re-design ofcompact microwave couplers with respect to operating frequency is discussed. Our methodology involves an inverse surrogate model setup using several reference designs optimized (at the level of equivalent circuit representation of the coupler) for a set of operating frequencies within a range of interest. The surrogate establishes the relationship between the operating frequency...

• Multiscalar Control Based Airgap Flux Optimization of Induction Motor for Loss Minimization

  Publikacja

  • T. Ayana
  • M. Morawiec
  • L. Wogi

  - IEEE Access - Rok 2024

  Based on the induction motor model, considering the core loss resistance that accounts for magnetic characteristic saturation, a speed control approach is devised with an adaptive full-order (AFO) speed observer. The induction motor model analysis is done sincerely in a stationary reference frame. The control approach incorporates a flux reference generator designed to meet optimal operational circumstances and a nonlinear speed...

• Multi-objective optimization of microwave couplers using corrected domain patching

  Publikacja

  • S. Kozieł
  • A. Bekasiewicz

  - Rok 2016

  Practical design of microwave components and circuits is a compromise between various, often conflicting objectives. In case of compact structures, the trade-offs are typically concerned with the circuit size and its electrical performance. Comprehensive information about the best possible trade-offs can be obtained by means of multi-objective optimization. In this paper, we propose a computationally efficient technique for identifying...
