  1. 11. mm Wave Near Field Spot Focus Technique in Free Space Dielectric  Properties Evaluation Method

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yanhan Liu; [2021]
    Keywords : Permittivity; near-field-focused NFF antenna; genetic algorithm; Permittivitet; närfältsfokuserad antenn; genetisk algoritm.;

    Abstract : Radomes were invented to protect sensitive antenna systems from the disturbing environment. Estimation of their permittivity is a vital step for their design. This project studies the free- space method to measure the permittivity of radome materials. READ MORE

    Abstract : There are more connected wireless devices than everbefore and with the rise of new smart systems such as self-drivingcars and smart cities new antenna solutions for transmittingsignals are needed. One important part of these systems is thefilters which filter out all the unwanted signals. READ MORE

  5. 14. Millimeter-Wave Radar data processing

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jonas Tran; [2020]
    Keywords : millimeter wave; radar; pulsed coherent radar; Technology and Engineering;

    Abstract : Based on the feasibility study [4], the goal of this master thesis is to compile custom firmware for the XM112 Pulsed Coherent Radar Module, which features a state of the art radar sensor integrated with a microcontroller unit (MCU). This allows the use of custom firmware to check the plausibility of real-time data processing on the radar signals and will lay some of the groundwork for further development of detection algorithms.

  6. 15. Beamforming in 5G mm-wave radionetworks : Importance of frequency multiplexing for users in urban macro environments

    University essay from Uppsala universitet/Signaler och system

    Author : Carl Lutnaes; [2020]
    Keywords : ;

    Abstract : 5G brings a few key technological improvements compared to previous generations in telecommunications. These include, but are not limited to, greater speeds, increased capacity and lower latency. These improvements are in part due to using high band frequencies, where increased capacity is found.
