  3. 2. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Natachai Terawatsakul; [2023]
    Nyckelord :;

    Sammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER
