1. 16. Anti-Reflective Coatings for 3D Printed Quasi-Optical Lenses: Experiments, Simulations, Verification, and Optimization

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Christina Ashok; [2022]
   Keywords : ;

   Abstract : 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. READ MORE

3. 17. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

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

   Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
   Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

   Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

4. 18. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jens Eilers Bischoff; [2022]
   Keywords : Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

   Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE

5. 19. Radar Based Solutions for Crushing andScreening Applications

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Emma Ehrlin; [2022]
   Keywords : Millimeter-wave radar; material mo Kalman filter; mass flow; volume flow; scanning; distance measurements; conveyor belt; Millimeter-wave radar; Kalman filter; massflöde; volymflöde; distansmätingar; transportband;

   Abstract : This project was carried out for a Company in the mining and construction business, and focused on the development of a radar based material monitoring solution for conveyor belts. A minor prestudy showed that there are possible customer values related to material monitoring solutions for equipment relevant for the Company, and that such solutions using radar possibly can fulfil the application requirements.
