    Sammanfattning : Antenna is a key component in wireless devices such as cell phones, laptops and smartwatches. With the new generation of Wi-Fi technology: Wi-Fi 6E coming out, 1200MHz bandwidth from 5.925GHz to 7.125GHz is freed for use. LÄS MER

  3. 2. 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.

    Sammanfattning : Developed for avalanche rescue, the RECCO Rescue System is used by more than 700 rescue organizations around the world to find buried avalanche victims and missing people. The RECCO system consists of two parts: a passive reflector integrated into clothing, boots, helmets, and body protection worn by skiers and riders; and an active detector used by organized rescue teams.

  5. 4. Optimering av antenndesign utifrån experimentella data

    Uppsats för yrkesexamina på grundnivå, Institutionen för teknik och naturvetenskap

    Författare :Antoinette Malki; [2003]
    Nyckelord :Datavetenskap; Optimering av antenndesign; Datavetenskap;

    Sammanfattning : During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. LÄS MER
