  1. 21. TUNABLE ANTENNAS FOR CLOSED-LOOP SYSTEMS

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : ManiChandana Chowki; Shrutha Keerthi Reddy Nagaiahgari; [2023]
    Keywords : Closed-loop Systems; Tunable Antennas; Radio Frequency RF ; MCU in closed-loop Systems; Adaptable Tuning; Antenna Impedance Matching Adaptive Antennas.;

    Abstract : Tunable antennas have emerged as a promising technology to address the challenges of achieving optimal performance across a wide range of frequencies. This abstract presents a study focused on designing and implementing an ideal antenna system design within a closed-loop system. Background. READ MORE

  2. 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)

    Author : Curt-Herman Normark Frisk; [2022]
    Keywords : Frequency Selective Surface; Microstrip Patch Element; Circular Polarisation; Phased Array Antenna; Single Feed; Frekvensselektiv Yta; Mikrostrip Patchelement; Cirkulär Polarisering; Fasstyrd Gruppantenn; Single-matad;

    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

  3. 23. 3D Printed Modulated Geodesic Lens Antenna With Even Coverage in the Far-Field

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

    Author : Harald Lindohf; Marcus Wikner; [2022]
    Keywords : 3D-printed; geodesic; modulated; Luneburg; beamforming; lens antenna;

    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.

  4. 24. Particle Simulation and Optimization of a Relativistic Magnetron for HPM Applications

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Wilhelm Thunberg; [2022]
    Keywords : Relativistic Magnetron; FOI Magnetron; TE11; HPM; High Power Microwaves; Particle in cell; MAgic3d;

    Abstract : 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

  5. 25. Design and Implementation of Cellular Network Hotspot Forecast Using Graph Convolutional Neural Networks

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Adrià Correas I Grifoll; [2022]
    Keywords : ;

    Abstract : 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
