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

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Natachai Terawatsakul; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Efficient High-level Synthesis Implementation of massive MIMO Processing on RFSoC

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sijia Cheng; [2022]
    Keywords : Technology and Engineering;

    Abstract : Massive multiple-input multiple-output (MIMO) refers to a wireless access technology that equips base station (BS) with hundreds to thousands of antennas to serve tens of user equipment (UE) in the same time-frequency resource. These extensive antennas improve spectral and energy efficiency, but the detection algorithms tend to be more complex with operations, multiplications, and inversions on larger size matrix.

  6. 5. Measurement of the surface resistivity with a cavity resonator

    University essay from Uppsala universitet/FREIA

    Author : Mathis Martin; [2021]
    Keywords : ;

    Abstract : The phenomena of radio-frequency vacuum breakdowns is an actual and concrete problem in the physics of particle accelerator since it causes damages in expensive devices. The surface resistivity of materials can be studied in order to better understand this event. READ MORE
