1. Characterization of Terminal Antennas for Diversity and MIMO Systems by Theory, Simulations and Measurements in Reverberation Chamber
Sammanfattning : This thesis is based on the work of designing and building a small reverberation chamber, and to use this chamber for characterization of antennas on mobile terminals such as phones. The characterization is done in terms of radiation efficiency, diversity gain and maximum available capacity. LÄS MER
2. Embedded Element Patterns in Combination with Circuit Simulations for Multi-Port Antenna Analysis
Sammanfattning : This thesis is a result from work on two different subjects, electromagnetic simulations of reverberation chambers and a methodology for the analysis of multi-port antennas. The subjects can be linked together by their contribution to knowledge in electromagnetic simulations and characterization of antennas. LÄS MER
3. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems
Sammanfattning : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure. LÄS MER
4. Phased array calibration and beamforming using signal processing
Sammanfattning : Array antennas have a wide range of applications which includesground and airborne radar, weather radar and anti-collision radar.In addition, equally important applications exist forcommunications, both on earth and to satellites in space, as wellas for medical applications such as the detection and treatment oftumors.

5. Change and Legitimation : Social Democratic Governments and Higher Education Policies in Sweden and Germany
Sammanfattning : Higher education has become a mega-topic in both political and scientific debate. Developments in systems of higher education and changes in the governance of such systems have been discussed in the literature. Such changes are brought about by collective actors within institutional settings. LÄS MER
