  1. 1. Magnetically tunable microwave resonator/filter

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE
