1. Antenna Arrays for Dual-Frequency Harmonic Radar Application
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. READ MORE

2. Simulation of the field generated by an array antenna with misplaced radiators
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : An array antenna is designed and commanded assuming a perfect positioning of the radiators. However, it is technically impossible to actually place each element in the exact position (mechanical, assembly errors and thermodynamic efforts), which generates errors in aim, amplitude and shape of the main beam while increasing the sidelobes.

3. Beam-Forming-Aware Link-Adaptation for Differential Beam-Forming in an LTE FDD System
University essay from Linköpings universitet/KommunikationssystemAbstract : The ability for base stations to be able to beam-form their signals, directing the signal energy to specific users, is a topic of research that has been heavily studied during the last decades. The beam-forming technique aims to increase the signal-to-interference-and-noise-ratio of the user and, consequently, increase the capacity and coverage of the communication system. READ MORE

4. Impact of Mutual Coupling among Antenna Arrays on the Performance of the Multipath Simulator System
University essay from Avdelningen för elektronik, matematik och naturvetenskapAbstract : This thesis work presents a study on the impact of mutual coupling among antenna arrays on the performance of the multipath simulator (MPS) system. In MIMO systems, it is a wellknown fact that the mutual coupling significantly affects their system performance. READ MORE

5. Design and Implementation of Quasi Planar K-Band Array Antenna Based on Travelling Wave Structures
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : Designing antenna arrays based on travelling wave structures has been studied extensively during the past couple of decades and literature on several array topologies is present. It has been an active area of research as constant improvement of antenna arrays is desired for different communication systems developed. READ MORE
