18. Near-Field Measurement System for 5G Advanced Antenna System at mm-Wavelength
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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

19. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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.
