1. Beam Steering Antenna Based on Continuous Transverse Stub Array and Flat Risley Prism Metasurface Lens
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Satellite communication is an integral part of society in this day and era. Due tobandwidth limitations communication frequencies have moved into higher frequencybandwidths. With the advancements in communication comes the demand for more efficientantennas due to the high attenuation of millimeter wavelength frequencies. READ MORE

3. Ray Tracing Algorithm for Dielectric Domes
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

4. 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)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.

5. Arbitrary motion Synthetic Aperture Radar
University essay from Lunds universitet/Matematisk statistikAbstract : 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
