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

    Author : Eduardo Salvador Lopez; [2023]
    Keywords : Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

    Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

  3. 2. Antenna Arrays for Dual-Frequency Harmonic Radar Application

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Venkatesh Raja; Mohammad Zafar Mohammad; [2023]
    Keywords : Technology and Engineering;

    Abstract : The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. READ MORE

  4. 3. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

    Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

  5. 4. Measurements, Estimations and Calibration with a Fully Digital Array

    University essay from Uppsala universitet/Signaler och system

    Author : Oscar Magnér; [2023]
    Keywords : WiDAR; signal processing; digital array; broadband antenna; array antenna; antenna; calibration; direct sampling; antenn; bredbandig; digital array; array antenn; direktsampling; signalbehandling; kalibrering; WiDAR; Saab AB; SAAB;

    Abstract : In modern digital communication, transmission and reception of information through electromagnetic signals requires digital devices that can process high data rates accurately despite being located in information heavy environments. One type of antenna receiver is the digital antenna array, which can steer its lobes electronically to increase or decrease sensitivity in specific directions. READ MORE

  6. 5. 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
