1. 3D Printed Modulated Geodesic Lens Antenna With Even Coverage in the Far-Field
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

2. Low-profile fully-metallic Luneburg lens antenna
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

3. Dual-polarized geodesic lens in sub-THz
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

4. Increasing the Crossover Levels of Beams in Geodesic Luneburg Lens Antennas
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

5. Active- integrated aperture lens antenna
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Luneburg lens antennas are gaining popularity in new communication systems, as increasingly higher frequencies are being used. Broadband fully- metallic implementations of Luneburg lenses, such as Rinehart- Luneburg lenses, constitute simple, cheap and efficient beamformers. READ MORE
