1. Millimeter-Wave Impulse Radio
Sammanfattning : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. LÄS MER
2. Micro- and Millimeter Wave CMOS Beamforming Receivers
Sammanfattning : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. LÄS MER
3. Microwave and millimeter wave CMOS Characterization, modeling, and design
Sammanfattning : The use of CMOS technologies for microwave and millimeter wave applications has recently been made possible as a result of increased transistor performance. The fT and fmax have, for example, passed 100 GHz at the 130 nm node and 200 GHz at the 65 nm node. LÄS MER
4. Millimeter Wave Imaging and Phased Array Antennas for 5G and Aerospace Applications
Sammanfattning : Phased array antennas are cornerstones in many proposed antenna solutions concerning the next generation of both airborne radar systems and wireless communication systems (5G). Additionally, millimeter wave (mm-wave) frequencies are expected to play an integral role in 5G, and are deemed well-suited for inspecting structural components used in the aerospace industry.
