1. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. Scann Loss Reduction on Phased Array Antenna
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. LÄS MER
3. Dual-polarized geodesic lens in sub-THz
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the sub-THz frequency range, the geodesic lens can realize low losses and beam scanning capability with high gain and high aperture efficiency due to its fully metallic property and rotational symmetry. Therefore, in high-frequency applications, a geodesic lens is considered a more promising solution in comparison to phased arrays or other beamforming techniques. LÄS MER
