  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.
