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. Estimation of Parabolic Microwave Antenna Movements Using Sensor Fusion
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : Wireless communication has seamlessly integrated itself into our daily lives, with Ericsson pioneering the development of comprehensive mobile ecosystems. As the demand for data traffic continues to surge, the enhancement of both cellular radio systems and backhaul infrastructure remains paramount. LÄS MER
3. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER
4. Comparative Analysis and Development of Receivers for Drone Remote Identification
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Similar to a car’s license plate, the European Union Aviation Safety Agency (EASA) has released new regulations imposing the registration of drone operators and the broadcasting of the drone’s “digital license plate”, i.e., the drone Remote Identification (RID) in flight, which gives a new opportunity in drone surveillance.

5. 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
