  1. 1. Investigation of Antenna Radomes in Low Earth Orbits

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Mathias Manohar Gren; [2023]
    Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Sammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

    Sammanfattning : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. LÄS MER

  4. 3. mm Wave Near Field Spot Focus Technique in Free Space Dielectric  Properties Evaluation Method

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Elektronisk utrustning som är placerade utomhus behöver väderskyddas. Detta kan göras med hjälp av antennskydd så kallade radomer som monteras på den elektroniska utrustningen. LÄS MER

  7. 5. Investigation of Wide Band mm-Wave Radome

    Master-uppsats, KTH/Elektroteknisk teori och konstruktion

    Författare :Shreyasi Bhowmik; [2017]
    Nyckelord :;

    Sammanfattning : “Radome” is a necessary shield for any type of antenna. Itsshape, thickness, mechanical and electrical properties defineits application. This thesis mainly revolves around thetechniques, used for radome analysis in W-band with thehelp of electromagnetic solvers of High Frequency StructureSimulator (HFSS) and CST Microwave Studio.
