  1. 1. Design and Evaluation of V/UHF Satellite Communication Antennas for Naval Applications

    Master-uppsats, KTH/Elektroteknisk teori och konstruktion

    Författare :Hampus Bäckström; [2018]
    Nyckelord :Antenna design; Antenna simulations; QHA; Submarine communication; SatCom; MUOS; Legacy; Antenndesign; Antennsimulering; QHA; Ubatskommunikation; Satellitkommunikation; MUOS; Legacy;

    Sammanfattning : In this master thesis, compact antenna design aimed towards naval applicationshave been designed, analyzed and evaluated. There is a recentinterest in the development of compact antennas to be used for smallersubmarine models, and with a smaller hull on a submarine, communicationand antenna systems must be adapted and minimized, which limitsantenna design.

  5. 5. Towards Long-Range Backscatter Communication with Tunnel Diode Reflection Amplifiers

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Gustav Eriksson; [2018]
    Nyckelord :Amplified backscatter tag; Reflection amplifier; Battery-free; Long-range communication; Tunnel diode; Ultra-low power consumption; RFID; Frequency shift;

    Sammanfattning : Backscatter communication enables wireless communication at a power consumption orders of magnitude lower than conventional wireless communication. Instead of generating new RF-signals backscatter communication leverages ambient signals, such as WiFi-, Bluetooth- or TV-signals, and reflects them by changing the impedance of the antenna. LÄS MER
