1. 21. Lean Beam Management for New Radio

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

   Author : Nawanit Kumar; [2020]
   Keywords : 5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

   Abstract : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. READ MORE

3. 22. Dual-polarized feed for mmWave lens antennas

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

   Author : Juan Luis Albadalejo Lijarcio; [2020]
   Keywords : ;

   Abstract : The fact of being bulky and not very cost-efficient made lens antennas not to be takenmuch into account in the past. Nowadays, this kind of antennas has attracted moreattention due to the increasing demand of higher frequencies in 5G, where lensesbecome considerably smaller. READ MORE

4. 23. Near-Field Measurement System for 5G Advanced Antenna System at mm-Wavelength

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

   Author : Bofei Wang; [2020]
   Keywords : Near-field; Measurement system; 5G; mm-wave length; antenna; Technology and Engineering;

   Abstract : An antenna is one of the most fundamental elements of wireless communication systems. The radiation behavior of antennas is characterized with the aid of the farfield radiation pattern. In this thesis, a near-field antenna measurement system is designed to predict the far-field pattern of antenna operational frequency 28 GHz and 39 GHz. READ MORE

5. 24. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

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

   Author : Hamid Yadegar Amin; [2020]
   Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

   Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

6. 25. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

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

   Author : David Anguiano Sanjurjo; [2020]
   Keywords : 5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

   Abstract : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.
