  1. 1. Gap waveguide for packaging microstrip filters & investigation of transitions from planar technologies to ridge gap waveguide

    Författare :Astrid Algaba Brazalez; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel plate mode; coupled line filter; microstrip circuit; packaging; Artificial magnetic conductor AMC ; perfect magnetic conductor PMC ; gap waveguide; transition.; coplanar waveguide CPW ;

    Sammanfattning : Gap waveguide technology has proved to constitute an effective alternative for the design of microwave passive components, due to its advantages with respect to traditional planar technologies and standard waveguides. There is no requirement for conductive contact between the two different metal pieces making up a gap waveguide prototype, since one of these pieces makes use of a textured surface that eliminates any possible leakage of the field through the gap to the surface of the other metal piece above it.

    Nyckelord :rectangular waveguide; packaging; transition; coplanar waveguide; microstrip; millimeter waves; gap waveguide; perfect magnetic conductor;

    Sammanfattning : The scarcity of available frequency bands for new wireless communication systems, as well as the growing need for higher capacity, motivates the current interest in moving upwards in frequency. The millimeter wave frequencyrange is very attractive to allocate potential commercial opportunities such as short range wireless communications that allow high-speed data/video transmission, and automotive radars for both driver assistance and increasedsafety.
