  - MICROWAVE AND OPTICAL TECHNOLOGY LETTERS - Rok 2011

  Two complementary miniaturization techniques have beenapplied to reduce the size of a rat-race hybrid coupler: (i) conventional microstrip sections have been replaced with their diminished lowimpedance counterparts as the first step of size reduction and (ii) novel fractal-shaped compact microstrip resonant cells dedicated to efficiently shorten low-impedance transmission line segments have been implemented as the second step of...

• A robust design of a numerically demanding compact rat-race coupler

  Publikacja

  • P. Kurgan
  • A. Bekasiewicz

  - MICROWAVE AND OPTICAL TECHNOLOGY LETTERS - Rok 2014

  A fast and accurate design procedure of a computationally expensive microwave circuit has been presented step-by-step and experimentally validated on the basis of a compact rat-race coupler (RRC) comprising slow-wave resonant structures (SWRSs). The final compact RRC solution has been obtained by means of a sequential optimization scheme exploiting the implicit space mapping (ISM) algorithm. A well-suited surrogate optimization...

  - INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING - Rok 2015

  In this article, a reliable and low-cost design methodology for simulation-driven optimization of miniaturized rat-race couplers (RRCs) is presented. We exploit a two-stage design approach, where a composite structure (a basic building block of the RRC structure) is first optimized using a pattern search algorithm, and, subsequently, the entire coupler is tuned by means of surrogate-based optimization (SBO) procedure. SBO is executed...

• A CMRC-based compact rat-race coupler with harmonic suppression

  Publikacja

  • A. Bekasiewicz
  • P. Kurgan

  - Rok 2013

  In this paper, an eective miniaturization technique exploiting compact microstrip resonant cells has been discussed and experimentally validated on the basis of a 3-dB microstrip rat-race coupler. The application of the method proposed has resulted in 91 % circuit area reduction in comparison to a conventional rat-race coupler. Experimental results show good agreement with theoretical characteristics, as well as an additional eect,...

  - Elektronika : konstrukcje, technologie, zastosowania - Rok 2009

  W referacie zaprezentowano projekt oraz wyniki eksperymentu podwójnie zminiaturyzowanego sprzęgacza pierścieniowego. Wstępny stopień miniaturyzacji uzyskano poprzez modyfikację impedancji charakterystycznych oraz długości elektrycznych odpowiednich sekcji linii mikropaskowych, natomiast dodatkową redukcję powierzchni osiągnięto poprzez implementację kaskad komórek PBG w odcinkach linii mikropaskowych. Wyniki eksperymentu potwierdzają...

• A compact microstrip rat-race coupler constituted by nonuniform transmission lines

  Publikacja

  • A. Bekasiewicz
  • P. Kurgan

  - MICROWAVE AND OPTICAL TECHNOLOGY LETTERS - Rok 2014

  In this work, a step-by-step development of a compact microstrip rat-race coupler (RRC) has been presented and discussed. A high degree of miniaturization has been obtained by substituting six quarter-wavelength uniform atomic building blocks of a RRC by their nonuniform counterparts. The miniaturization procedure has been realized in three progressive steps: (i) the first layout solution of a miniaturized RRC has been acquired...

• Inflation Forecast or Forecast(s) Targeting?

  Publikacja

  • K. Tura-Gawron

  - Romanian Journal of Economic Forecasting - Rok 2018

  The paper refers to L.E.O. Svensson’s concept of inflation forecast targeting (IFT) and its implementation by central banks of Sweden, Norway and the Czech Republic. The study focuses on (1) inflation forecasts published by selected central banks, i.e.headline inflation and core or monetary policy-relevant (MPR) inflation, which are made on the assumption of endogenous instrument rate, (2) one-year consumer...
