6. Microstrip Antennas for 60 GHz Band Application
Sammanfattning : The next generation of mobile networks will exploit frequencies above 5 GHz and will use a wide available bandwidth for high speed data communication. At the time of writing this thesis work is ongoing to launch into the market a communication system operating between 25 GHz and 30 GHz. LÄS MER
7. Investigation of GaAs structures for microstrip detectors
Sammanfattning : The performance of Gallium Arsenide p-i-n detectors afterneutron irradiation has been studied. The detectors have beenirradiated with » 6 MeV neutrons at various neutronfluences up to approximately 6 ¢ 1014 n/cm2, protons andmixed beam up to 1015 p/cm2. LÄS MER
8. Slot Array Antennas at V-band based on Inverted Microstrip Gap Waveguide
Sammanfattning : Recently, gap waveguide technology is introduced as a proper guiding structure for millimeter-systems. The conception of gap waveguide technology can be modeled for theoretical analysis by two parallel plates, a top perfect electric conductor layer and a bottom perfect magnetic conductor layer.

9. Characterization of losses in ridge, groove and microstrip gap waveguides
Sammanfattning : The gap waveguide is a new technology that recently has been presented as an attractive candidate for applications at millimeter and sub millimeter waves. The waveguide is generated in the gap between a smooth upper metal plate and a ridge (or a groove) in a textured lower metal plate. LÄS MER
10. Gap Waveguide Technology for Millimeter Wave Applications and Integration with Antennas
Sammanfattning : The increasing advance of short range wireless communications requiring high data rates and the lack of available spectrum have driven researchers and industry to move towards higher frequencies, in particular to the millimeter wave range. The opening of this wide portion of free spectrum has risen a large interest in developing mm-wave communication systems for commercial applications. LÄS MER
