1. Near Field millimeter Wave Antenna Measurements
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. LÄS MER
2. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
3. Geodesic Lens Antenna for sub-THz Imaging
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Millimiter Wave (mmW) frequency band, characterized by a high atmospheric attenuation and wide available bandwidth has become of big interest for high accuracy radar imaging applications. The continuous development of the Monolithic Microwave Integrated Circuit (MMIC) technology yields to the appearance of different commercial-off-the-shelf (COTS) radar transceivers at that frequency band, where the antennas are fully integrated into the chip.

4. Near-Field Measurement System for 5G Advanced Antenna System at mm-Wavelength
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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. LÄS MER
5. Designing a Hyperbolic Lens Antenna using 3D Printing Technology
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : To increase capacity, lower latency, and boostdata rates, new higher gain antennas that can transmitmillimeter-waves are needed. Dielectric lens antennas arean attractive potential solution. LÄS MER
