  1. 1. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ossian Kynman; [2023]
    Keywords : MIMO; Diversity Gain; Capacity; Correlation; Fading;

    Abstract : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. READ MORE

  3. 2. Dataset based on volunteer campaign to optimize novel sensor for muscle quality

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Sophia Holmqvist; [2022]
    Keywords : sarcopenia; microwaves; medical imaging;

    Abstract : This project had its primary focus on running a campaign to recruit healthy volunteers for a test study involving the utilization of a microwave sensor and ultrasound measurements. The key system used was the Muscle Analyzer System (MAS), which consisted of the Bandstop Filter Sensor (BFS), a microwave sensor transmitting microwaves into the selected medium through transmission and a FieldFox Vector Network Analyzer which was used to transmit these microwaves.

  4. 3. Graphene-based Crack-Free Ceramic Coatings for High-Performance Passive RF Devices

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

    Author : Haomin Liu; [2021]
    Keywords : ;

    Abstract : Dielectric resonators coated with highly conductive metallic layers are widely used in radio frequency (RF) applications. The quality factor (Q-factor) of resonators is a key figure-of-merit that describes the loss and the energy efficiency of the resonators. READ MORE

  5. 4. Analysis of RISE's VIRC for Automotive EMC Immunity Testing

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Andreas Lundberg; [2021]
    Keywords : Electromagnetic Compatibility EMC ; Reverberation Chamber RC ; Vibrating Intrinsic Reverberation Chamber VIRC ; Cumulative Distribution Function CDF ; Rayleigh Distribution; Vector Network Analyzer VNA ; Immunity testing;

    Abstract : RCs (Reverberation Chambers) has historically been used mainly for aerospace and military purposes in EMC (Electromagnetic Compatibility) testing, but the interest also seems to increase in the automotive industry (the development of an international standard for vehicles is in progress). The vehicles of the future will most likely be electrified, wirelessly connected and autonomous, i. READ MORE

  6. 5. 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
