  1. 1. A Novel and an Efficient Design of an Inverted F-Antenna for Bluetooth Low Energy Communications

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Amer Khatib; [2019]
    Nyckelord :Antenna; Communication; design; testing; Wireless communications; bluetooth.;

    Sammanfattning : Constantly, antenna plays an important role in expanding the wireless communication systems in different technology applications for example, but not limited to, IoT communications and automotive radar systems. On the other hand, the Bluetooth-Low-Energy (BLE) benefits different sorts of applications, as it offers (i) a very low power consumption, (ii) a very fast data transfer, (iii) and an inexpensive/efficient solution as well.

  2. 2. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Richard Hedlund; [2019]
    Nyckelord :Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

    Sammanfattning : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.

    Sammanfattning : Antennas are one of the most sensitive elements in any wireless communication equipment. Designing small-profile, multiband and wideband internal antennas with a simple structure has become a necessary challenge. LÄS MER

  5. 5. Low-dispersive Leaky-wave Antennas: A Viable Approach for Fifth Generation (5G) mmWave Base Station Antennas

    Master-uppsats, KTH/Elektroteknisk teori och konstruktion

    Författare :Oskar Dahlberg; [2019]
    Nyckelord :;

    Sammanfattning : In this work, a method to achieve reduced beam-squint in fully metallic leaky-wave antennas is proposed and its applicability for high frequency, high gain, base station antennas in future communication networks is indicated. The antenna is built in gap waveguide technology, where the fundamental mode is allowed to leak by removal of one of the waveguide walls. LÄS MER
