  - Elektronika : konstrukcje, technologie, zastosowania - Rok 2009

  W artykule omówiono koncepcję miniaturyzacji sekcji linii mikropaskowej poprzez modyfikację brzegu linii oraz warstwy metalizacji masy. W pracy zaprezentowano projekt oraz wyniki eksperymentu sprzęgacza gałęziowego skonstruowanego w oparciu o linię meandrową z zaburzoną warstwą metalizacji masy. Pomierzone charakterystyki transmisyjne potwierdzają atrakcyjność zastosowanych metod redukcji zajmowanej przez układ powierzchni. Osiągnięto...

• Resonant Frequencies in the Open Microstrip Structures Placed on Curved Surfaces

  Publikacja

  • R. Lech
  • A. Kusiek

  - Rok 2016

  The paper presents the research on open microstrip structures placed on curved surfaces such as cylindrical, elliptical or spherical. The numerical analysis of investigated structures is based on expansion of electric and magnetic fields into suitable function series. Utilizing the continuity conditions the boundary problem is formulated which is solved with the use of method of moments. The investigated structures find application...

• Resonance Frequency Calculation of Spherical Microstrip Structure Using Hybrid Technique

  Publikacja

  • A. Kusiek
  • R. Lech
  • P. Kowalczyk
  • W. Marynowski

  - Rok 2015

  In this paper the spherical microstrip structure is considered. The structure is composed of a metallic patch with an arbitrary shape placed on a dielectric coated metallic sphere. In the analysis the hybrid technique is utilized. In this approach the finite-difference technique is applied in a cavity model to determine the current basis functions on the patch. Next, using method of moments, the resonance frequency of the structure...

• Novel structure and EM-driven design of miniaturized microstrip rat-race coupler

  Publikacja

  • A. Bekasiewicz
  • S. Kozieł

  - Rok 2018

  In this paper, a novel structure and design procedure of a miniaturized microstrip rat-race coupler (RRC) is described. Small size of the RRC is achieved by folding the transmission lines of the conventional circuit into its interior, as well as by implementation of the structure on three layers. The final size of the coupler realized for the operating frequency of 1 GHz is only 220 mm2, which gives over 95% footprint reduction...

• Novel microstrip low-pass filters with fractal defected ground structures

  Publikacja

  • P. Kurgan
  • M. Kitliński

  - MICROWAVE AND OPTICAL TECHNOLOGY LETTERS - Rok 2009

  In this study, three microstrip low-pass filters (LPFs) containing fractal-shaped defected ground structures have been designed and manufactured. To improve the performance of microstrip LPF, cascades of inductively coupled fractal resonators have been applied. Simultaneously, to achieve relatively constant microstrip impedance resulting in essentially low reflection losses, a modification of the strip geometry has been introduced....
