  - Year 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...

  - Year 2015

  The resonance frequency problem of an ellipticalrectangular patch mounted on multilayered dielectric coated elliptic conducting cylinder, is investigated in this paper. A fullwave analysis and a moment-method calculation are employed. The analysis is carried out considering the expansion of the field as a series of Mathieu functions. An additional theorem for Mathieu functions is utilized to investigate the non-confocal ellipse...

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Year 2015

  Artykuł prezentuje wyniki badań otwartych struktur mikropaskowych umieszczonych na powierzchniach cylindrycznych, eliptycznych lub sferycznych. Analiza numeryczna badanych struktur oparta jest na rozwinięciu pól elektrycznych i magnetycznych w odpowiednie szeregi funkcyjne. Korzystając z warunków ciągłości pól formułowane jest zagadnienie brzegowe, które rozwiązywane jest przy wykorzystaniu metody momentów. Badane struktury mają...

  • A. Kusiek

  - Year 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...
