  5. 3. Gap Waveguide Technology- Electromagnetic Packaging and Transitions

    Author : Astrid Algaba Brazalez; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rectangular waveguide; packaging; transition; coplanar waveguide; microstrip; millimeter waves; gap waveguide; perfect magnetic conductor;

    Abstract : 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.
