1. 1. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27

   University essay from Umeå universitet/Institutionen för fysik

   Author : Oskar Hellström; [2023]
   Keywords : ;

   Abstract : Base stations (BSs) are the cornerstone that enables wireless communications. In order for a new BS variant to be imported and sold in the US they are required to undergo electromagnetic compatibility (EMC) testing. This testing is necessary to obtain their Federal Communications Commission (FCC) certification. READ MORE

3. 2. Assessment of Exposure to Electromagnetic Fields from Distributed MIMO Antennas

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

   Author : Frans Nyberg Zou; [2022]
   Keywords : 6G; Distributed MIMO; Electromagnetic field exposure; Hybrid simulations; 6G; Distribuerad MIMO; Exponering av elektromagnetiska fält; Hybridsimueringar;

   Abstract : Research on 6G telecommunication networks has been initiated. Among all potential technology components, the distributed multi-input multioutput (D-MIMO) technology is one of the promising enablers. Due to the new technology solutions, additional methodologies for assessment of electromagnetic field (EMF) exposure need to be developed. READ MORE

4. 3. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

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

   Author : Vinodhini Mylai Chandrasekaran; Nikhila Chinnayanapalli Ravi; [2022]
   Keywords : Antenna Design; mmWave frequency; 5G; FEKO; Technology and Engineering;

   Abstract : The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and many more such applications.

5. 4. 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

6. 5. Simulating flow-noise for after-treatment systems

   University essay from KTH/Teknisk mekanik

   Author : Adam Sandström; [2020]
   Keywords : Flow-noise; CAA; DES; non-refelctive boundary conditions; stretched grid; Menter SST;

   Abstract : Modern silencers for heavy vehicle applications are designed to cancel out the sound generated by the effects of combustion and propagation of exhaust gases through the engine after-treatment system. The complex geometry within the compact silencer give rise to self generated (or flow-) noise that contribute to the total sound power radiated at the exhaust outlet. READ MORE
