1. 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
2. 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
3. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. LÄS MER
4. Scanning range extension by combining arrays with lenses
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Array antennas, and more specifically phased array antennas, are widely used in radar detection and communication systems because of their excellent beam scanning ability and simple control. Generally speaking, the scanning function can be realized in two ways: mechanically or electronically. LÄS MER
5. Anti-Reflective Coatings for 3D Printed Quasi-Optical Lenses: Experiments, Simulations, Verification, and Optimization
Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhetSammanfattning : This thesis aims to see how well anti-reflective coatings created for dense material millimeter wave integrated lens work and to validate observations using electromagnetic simulation. The dielectric material was chosen for lens fabrication because it allows for high power transfer capability via the lens and allows the production of affordable and compact-size lenses. LÄS MER
