  1. 1. A Comparison Between Applied Square and Ring CSRR on SIW Using the HOM Method

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carl Nordengren; Johan Bellbrant; [2022]
    Nyckelord :Split-ring resonators; bandgap-filter; higher order modes method; substrate integrated waveguide; periodic structures;

    Sammanfattning : The rise of connected devices and the internet of things has increased the need for systems capable of transmitting high frequency signals wirelessly. An important part of these systems are the filters. Filters remove signals within unwanted frequency ranges. These filters can be implemented using e. LÄS MER

  3. 2. Magnetically tunable microwave resonator/filter

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Zhi Ye; [2022]
    Nyckelord :Magnetic tuning; Ferrite; Substrate integrated waveguide resonator; Substrate integrated waveguide filter; Magnetisk inställning; Ferrit; Substratintegrerad vågledarresonator; Substratintegrerad vågledarfilter;

    Sammanfattning : The magnetic tunability of ferrites has been studied and applied on many electric components for working in various frequency bands. Filters or resonators loaded by ferrites can thus work for different frequency requirements by tunning external biasing field. However, filters or resonators built by traditional waveguides are large in size. LÄS MER

  4. 3. Analysis and Design of Microwave Reconfigurable Filters in ESIW Technology

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Juan Rafael Sánchez Marín; María Trinidad Juliá Morte; [2015]
    Nyckelord :Reconfigurable; Microwave; Filters; ESIW; Empty; Substrate; Integrated; Waveguide;

    Sammanfattning : Microwave filters are essential components in high frequency communication systems. The features required for these devices are increasing due to the increase in frequency, caused by the saturation of the electromagnetic spectrum. LÄS MER

  5. 4. Compact and Integrated Broadband Antennas : for wireless applications

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Muhammad Afzal Sadiq; [2012]
