  1. 1. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    University essay from Uppsala universitet/Signaler och system

    Author : Alexander Söderlund; [2023]
    Keywords : VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Abstract : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. READ MORE

  3. 2. Modelling and Control of the Steering in an Articulated Forklift using Rapid Control Prototyping

    University essay from Linköpings universitet/Reglerteknik

    Author : Alexander Lilja; Filip Leijonhufvud; [2023]
    Keywords : ;

    Abstract : This report focuses on the steering of a Very Narrow Aisle (VNA) forklift, which undergoes frequent transitions between manual and wire guidance modes. Manual operation is employed outside narrow aisles, while wire guidance mode is utilized within them. READ MORE

  4. 3. 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

  5. 4. 3D Coating of Interface Materials for High-Performance RF Passive Devices

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

    Author : Xiner Shen; [2023]
    Keywords : Ceramic coating; Dip coating; Radio frequency; Passive RF devices; Quality factor; Keramisk beläggning; Dip-beläggning; Radiofrekvens; Passiva RF-enheter; Kvalitetsfaktor;

    Abstract : The demand for high-performance Radio Frequency (RF) passive devices has been steadily increasing due to the growing complexity and sophistication of wireless communication systems. The Quality factor (Q-factor) is a key parameter for describing the signal losses and the energy efficiency of resonators. READ MORE

  6. 5. 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.
