1. 3D Printed Modulated Geodesic Lens Antenna With Even Coverage in the Far-Field
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The development of 5G and 6G entails new demandson antennas. This includes fast and reliable connections to a largenumber of devices. A wider area of coverage, and thus moreantennas are also expected, which is problematic for the expensiveantennas used today. To meet those demands, a geodesic lensantenna has been proposed. LÄS MER
2. Low-profile fully-metallic Luneburg lens antenna
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Modern communication systems face new technological challenges, such as the narrowness and overload of the conventional frequency bands employed for these applications. Nowadays, communication systems are expected to operate at higher frequencies, such as the mm-wave band. 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
4. Increasing the Crossover Levels of Beams in Geodesic Luneburg Lens Antennas
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The new and forthcoming generation of mobile networks intend to operate at considerably higher frequencies than the previous systems. This lift in frequency of operation alleviates today’s communication systems’ crowded bandwidth and allows for faster data rates than previously possible. LÄS MER
5. 3D-Printed Geodesic Reflective Luneburg Lens Antenna for X-Band
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : With the rise of 5G and the increasing number ofdevices, novel antenna designs are needed to meet the demandof the future. In this report, the authors present a design andexperimental verification of a 3D-printed Geodesic ModulatedReflective Luneburg lens antenna working at the X-Band, 8-12GHz. LÄS MER
