  1. 1. Near Field millimeter Wave Antenna Measurements

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Bharath Manjunatha; [2023]
    Keywords : Antenna Pattern; Near field to far field; Planar Scanning; Probe Compensation; Active Antenna; Technology and Engineering;

    Abstract : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. READ MORE

  3. 2. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

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

    Author : Jens Eilers Bischoff; [2022]
    Keywords : Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

    Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE

  4. 3. Geodesic Lens Antenna for sub-THz Imaging

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

    Author : Joan Mitjans i Blasco; [2021]
    Keywords : ;

    Abstract : The Millimiter Wave (mmW) frequency band, characterized by a high atmospheric attenuation and wide available bandwidth has become of big interest for high accuracy radar imaging applications. The continuous development of the Monolithic Microwave Integrated Circuit (MMIC) technology yields to the appearance of different commercial-off-the-shelf (COTS) radar transceivers at that frequency band, where the antennas are fully integrated into the chip.

  5. 4. Near-Field Measurement System for 5G Advanced Antenna System at mm-Wavelength

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Bofei Wang; [2020]
    Keywords : Near-field; Measurement system; 5G; mm-wave length; antenna; Technology and Engineering;

    Abstract : An antenna is one of the most fundamental elements of wireless communication systems. The radiation behavior of antennas is characterized with the aid of the farfield radiation pattern. In this thesis, a near-field antenna measurement system is designed to predict the far-field pattern of antenna operational frequency 28 GHz and 39 GHz. READ MORE

  6. 5. Designing a Hyperbolic Lens Antenna using 3D Printing Technology

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

    Author : Alexander Thorell; Jonas Cederberg; [2020]
    Keywords : 3D printing; Lens antennas; Hyperboliclenses; Permittivity measurement; Telecommunication;

    Abstract : To increase capacity, lower latency, and boostdata rates, new higher gain antennas that can transmitmillimeter-waves are needed. Dielectric lens antennas arean attractive potential solution. READ MORE
