  1. 1. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

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

    Author : Ashray Ugle; [2023]
    Keywords : Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

    Abstract : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.

  2. 2. Arbitrary motion Synthetic Aperture Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Alberius; Erik Rolander; [2023]
    Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

  3. 3. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

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

    Author : Vinodhini Mylai Chandrasekaran; Nikhila Chinnayanapalli Ravi; [2022]
    Keywords : Antenna Design; mmWave frequency; 5G; FEKO; Technology and Engineering;

    Abstract : The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and many more such applications.

  4. 4. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

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

    Author : Hamid Yadegar Amin; [2020]
    Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

    Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

  5. 5. Investigating the Effect of Antenna Polarization on the Performance of CoMP Systems based on Synchronous Multi-link Measurements

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

    Author : Sakib- Bin- Redhwan; Ahmad Shekhan; [2016]
    Keywords : CoMP; MU-MIMO; Sum-rate Capacity; Beamforming; Technology and Engineering;

    Abstract : In this master thesis work, the effect of polarization, at the Base Station (BS) side, on the performance of multi-user Coordinated Multipoint (CoMP) systems is studied. This study was performed using synchronous multi-link measurements that took place at the campus of the faculty of Engineering, LTH, Lund University, Lund, Sweden, where two different BS setups were studied.
