  1. 1. Wideband Dielectric Resonator Antenna Array for Autonomous Vehicles

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Andreas Johansson; Luke Müller; [2023]
    Keywords : DRA; dielectric resonator antenna; 5G; FR2; 28GHz; NR; antenna; circular polarization; autonomous vehicles;

    Abstract : With the rapid advancement of autonomous vehicles, reliable and efficient wireless communication systems with high data rates have become essential for their safe and efficient operation and further evolution. High data rates are found in the higher frequency bands where conductive antennas lack radiation efficiency. READ MORE

  3. 2. 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.

  6. 5. Enhancement of SAR Image Resolution with Implementation of Circular GB-SAR System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Dheeraj Nehru Neravati; [2013]
    Keywords : Synthetic Aperture Radar; UWB; GB-SAR; Circular SAR; Circular Aperture; Resolution; Enhancement; Radar; GBP;

    Abstract : Radars were used for surveillance and remote sensing but nowadays they handle a vast range of applications, radar imagery being one of them. The need for high resolution images was inevitable which lead to Synthetic Aperture Radar (SAR) systems. SAR plays a prominent role in remote sensing applications and geophysical studies. READ MORE
