1. 1. Antenna Options for High Altitude IMT Base Stations (HIBS) in Cellular Networks

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Harald Magnusson; [2022]
   Keywords : High altitude IMT Base Station HIBS ; High Altitude Platform Station HAPS ; Link Feasibility; Coverage Feasibility; Phased Array Antenna; Parabolic Reflector Antenna;

   Abstract : This thesis is the result of a collaboration between Ericsson AB and Luleå University of Technology. A feasibility study has been conducted to investigate antenna options for the HIBS access link. The study contains two parts. Firstly, a link budget investigating the gain required from the antenna.

3. 2. Electromagnetic Phase Engineering With Metamaterials

   University essay from KTH/Tillämpad fysik

   Author : Olof Sjödin; [2021]
   Keywords : Applied Physics; Electromagnetism; Metamaterials; MIM; Plasmonics; FEM; Reflector design; Phase engineering; Tillämpad fysik; Elektromagnetism; Metamaterial; MIM; Plasmonics; FEM; Reflektor design; Fasdesign;

   Abstract : Metamaterials are artificially designed materials with desired electromagneticresponses for advanced wave manipulation. Their key constituent is often somenoble metal, thanks to its well localized plasmonic effects with highextinction cross section. READ MORE

4. 3. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Akila Wajirakumara; [2021]
   Keywords : ;

   Abstract : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.

5. 4. Analysis of the Solarus C-PVT solar collector and design of a new prototype : Market review and Production process guideline

   University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

   Author : Xabier Saizar Zubeldia; Gerard Vila Montagut; [2016]
   Keywords : Solar Collector; Photovoltaic Thermal Hybrid; MaReCo; Concentrating PVT;

   Abstract : Finding cleaner and sustainable energy resources is one of the most important concerns for the development of humanity. Solar energy is taking an essential role in this matter as the production cost of solar collectors is decreasing and more solar installations are being set up every year throughout the world.

6. 5. Physical Structures for Signal Separation

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Albin Nordsjö; [2016]
   Keywords : Signal separation; physical; parabolic reflector; reflector; signal processing; Technology and Engineering;

   Abstract : This master’s thesis studies the use of physical structures for signal source separation. A parabolic reflector was used to alter the directional properties of one microphone in a two-microphone array. A method to estimate the mixing channels from measured data is presented, as well as a method to find the optimal separating channels. READ MORE
