22. Design of an Array of Patch-elements With a Band-pass Frequency Selective Surface Hybrid Radome : Analysis and characterisation of a frequency selective surface and a phased array antenna
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : A circular polarised phased array antenna and a frequency selective hybrid radome are designed and evaluated. The antenna system is well suited as a part of a communication link between platforms with a 600 MHz bandwidth and a centre frequency of 5 GHz. READ MORE

23. 3D Printed Modulated Geodesic Lens Antenna With Even Coverage in the Far-Field
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The development of 5G and 6G entails new demandson antennas. This includes fast and reliable connections to a largenumber of devices. A wider area of coverage, and thus moreantennas are also expected, which is problematic for the expensiveantennas used today. To meet those demands, a geodesic lensantenna has been proposed. READ MORE

24. Particle Simulation and Optimization of a Relativistic Magnetron for HPM Applications
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : A relativistic magnetron (RM) is a high-power microwave (HPM) source. The main objective of the RM is to generate directed electromagnetic pulses with high power, which can be used in e.g. HPM weapons and for electromagnetic compatibility testing. READ MORE

25. Design and Implementation of Cellular Network Hotspot Forecast Using Graph Convolutional Neural Networks
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : This project proposes a type of (Recurrent) Graph Neural Network (RGNN) to predict future hotspots in cellular network data. Current state-of-the-art algorithms process each antenna (celldata )’s in isolation, ignoring the performance of nearby cells and cell locations. READ MORE
