1. Beam Steering Antenna Based on Continuous Transverse Stub Array and Flat Risley Prism Metasurface Lens
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
2. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
3. Ray Tracing Algorithm for Dielectric Domes
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
4. Beam-steered Modulation in Advanced Antenna System
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. LÄS MER
5. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknikSammanfattning : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. LÄS MER
