  1. 1. Millimeter Wave Imaging and Phased Array Antennas for 5G and Aerospace Applications

    Författare :Jakob Helander; Teoretisk elektroteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; phased array; Millimeter wave antenna arrays; millimeter wave imaging; Computational Electromagnetics; Non-destructive testing NDT ; compressive sensing;

    Sammanfattning : Phased array antennas are cornerstones in many proposed antenna solutions concerning the next generation of both airborne radar systems and wireless communication systems (5G). Additionally, millimeter wave (mm-wave) frequencies are expected to play an integral role in 5G, and are deemed well-suited for inspecting structural components used in the aerospace industry.
