  1. 21. Compact Ku-band Microwave Filters Realised using Suspended Integrated Stripline Technology

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

    Author : Henrik Åkerberg; [2023]
    Keywords : Suspended Substrate Stripline; Microwave filter; Low Profile; Quasi-Planar; Bandpass Filter; Hängande-Substrat-Stripline; Mikrovågsfilter; Låg profil; Kvasi-planar; Bandpassfilter;

    Abstract : As the fifth generation of telecommunications is deployed, and the number of devices transmitting in the microwave bands grows, effective filtering technologies are becoming ever more important. When a filter is designed, some performance trade-offs have to be made, and one of them is the trade-off between filter size and electrical performance. READ MORE
