  1. 1. Design and Fabrication of Ultra-Wideband Bandpass Filter Based on Liquid Crystal Polymer Substrates

    Författare :Xia Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bandpass filter; Automotive radar systems; Liquid crystal polymer substrate; Ring-resonator theory; Ultra-wideband; Millimeter wave;

    Sammanfattning : For millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and consequently higher constraints. From a material’s point of view, the selection of substrate material has recently drawn considerable attention in the design of the whole mm-wave system. LÄS MER

  3. 2. Some studies on metamaterial transmission lines and their applications

    Författare :Xin Hu; Sailing He; Ferran Martin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metamaterial; transmission line theory; composite right left-handed transmission line; diplexer; coupler; balun; interdigital capacitor; split ring resonator; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis focuses mostly on investigating different potential applications of meta-transmission line (TL), particularly composite right/left handed (CRLH) TL, and analyzing some new phenomena and applications of meta-TL, mostly left-handed (LH) TL. Realization principle will also be studied. LÄS MER

  4. 3. Design, Fabrication and Characterization of Microwave Passive Devices on Liquid Crystal Polymer Substrates

    Författare :Xia Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-planar waveguide; parallel-coupled line resonator; dual-mode ring resonator; millimeter wave; ultra-wideband; Bandpass filter; liquid crystal polymer substrate; printed monopole antenna;

    Sammanfattning : For microwave/millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and constraints. The materials presently used as mm-wave substrates are either expensive or show unsatisfactory performance. LÄS MER
