6. Design and Test of: Wide Band and Highly Polarized Antenna for 60GHz
Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : In this work high gain antennas are investigated for the 60 GHz frequency. The goal is to produce a high bandwidth point-to-point wireless network that could enable improved and new features in embedded systems used to detect particles in high energy physics. A literature study was performed aiming at simple, high gain, highly polarised antennas. LÄS MER
7. Millimetre-Wave Spectrum Sharing in Future Mobile Networks : Techno-Economic Analysis
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Mobile operators passed through many phases in the market over the last several years, since the beginning of mobile broadband services. When the first smart phone was introduced in 2007, it caused a huge increase in the traffic and the users demand kept on increasing. LÄS MER
8. The application of D2D communication in 60 GHz millimeter wave transmissions
Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)Sammanfattning : Motivated by the increase of traffic load in cellular network and the associated increase of traffic through the network, device-to-device (D2D) communication with 60GHz millimeter wave (mmWave) is a possible solution to manage this future task. In this research project, our investigation focuses on the benefits of combining D2D links and conventional links with 60 GHz mmWave. LÄS MER
9. Automated scan station for 3D measurements of millimetre wave antennas
Uppsats för yrkesexamina på grundnivå, Mikrovågs- och terahertzteknikSammanfattning : As the importance of high frequency antennas increase in the world so does the needfor accurate measurements of the antenna performance.This project has endeavoured to create an automated scan station that can measurethe antenna performance from an EHF (extremely high frequency) antenna.These points are measured spherically around the antenna.

10. MPD-vågformer för helikopterradar
Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknikSammanfattning : A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). LÄS MER
