  • Zespół Inżynierii Mikrofalowej i Antenowej

    Specjalność badawcza KIMiA wiąże się z techniką b.w.cz. i dotyczy zakresu częstotliwości od setek megaherców do kilkudziesięciu gigaherców. Przedmiotem badań teoretycznych (analiza, synteza, symulacja i modelowanie komputerowe,) oraz eksperymentalnych są elementy (prowadnice, sprzęgacze, rozgałęzienia) oraz układy pasywne (cyrkulatory, przesuwniki fazy, obciążenia, tłumiki) i aktywne (wzmacniacze, mieszacze, powielacze, modulatory),...

  • Millimeter Wave Retrodirective Van Atta Arrays in LTCC Technology

    Publication

    The millimeter wave Van Atta arrays, intended for chipless RFID applications and fabricated in LTCC technology, are presented in this paper. The arrays are designed for 24 GHz and 60 GHz bands. The method for an easy modification of the RCS characteristic by increasing the number of single-dimensional arrays, intended for increasing the RCS level, is also presented. The LTCC manufacturing process is described in detail. The fabricated...

  • Simple Millimeter Wave Identification System Based on 60 GHz Van Atta Arrays

    The paper presents a proof-of-concept of a millimeter-wave identification system based on Van Atta array tags in the 60 GHz band. For interrogation of the tags, a vector network analyzer and a measurement transceiver were employed in alternative test configurations. The design, fabrication and measurements of co- and cross-polarized Van Atta arrays are presented in the paper. They can be treated as simple chipless RFID tags with...
