  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. III-V Nanowire MOSFETs for mm-Wave Switch Applications

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

    Author : Marcus Sandberg; [2020]
    Keywords : III-V Nanowire MOSFET; millimeter wave mmW ; millimeter-wave integrated circuit MMIC ; single-pole double-throw SPDT ; Technology and Engineering;

    Abstract : RF-switches are key components in many electronic devices as they enable routing of higher frequency signals. Increasing demands on device performance requires new technologies as well as new approaches to designs of circuits. III-V nanowire MOSFETs are a promising device technology well suited for implementation of switches. READ MORE

  6. 5. High Performance Reference Crystal Oscillator for 5G mmW Communications

    University essay from Linköpings universitet/Elektroniska komponenter; Linköpings universitet/Tekniska högskolan

    Author : Tahmineh Torabian Esfahani; Stefanos Stefanidis; [2014]
    Keywords : Crystal Oscillator; 5G; mmW Communications; Oscillator Desing;

    Abstract : Future wireless communications (often referred to as 5G) are expected to operate at much higher frequencies compared to today’s wireless systems. During this thesis, we have investigated the option to use high frequency crystal oscillators, which along with a PLL, will generate the RF LO signal in the mmW range. READ MORE
