2. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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

3. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE

4. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE
