  1. 1. Ultra-wideband Antenna and Radio Front-end Systems

    Författare :Magnus Karlsson; Anders Rydberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communication; ultra-wideband; radio communication; UWB bandwidth; antenna parallelism; Electrical engineering; Elektroteknik;

    Sammanfattning : The number of wireless communication applications increase steadily, leading to the competition for currently allocated frequency bands. Pressure on authorities around the world to permit communications in higher and wider frequency ranges to achieve higher wireless capacity than those existed in the past has resulted in several new specifications.

  2. 2. 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
