1. Integrated Antennas : Monolithic and Hybrid Approaches
Sammanfattning : This thesis considers integration of antennas and active electronics manufactured on the same substrate. The main topic is on-chip antennas for commercial silicon processes, but hybrid integration using printed circuit board technology is also addressed. LÄS MER
2. Analysis and Design of Base Station Antennas for Mobile Communications
Sammanfattning : The thesis deals with base station antennas and the environment they work in. Polarization diversity, dual band operation, and adaptive antenna systems are discussed with emphasis on how antennas for these applications should be designed. We compare the polarization diversity performance of different types of dual polarized antenna elements. LÄS MER
3. Direction finding, beamforming and mutual coupling in base station antenna arrays
Sammanfattning : .... LÄS MER
4. Polarization diversity and array signal processing in base station antennas
Sammanfattning : .... LÄS MER
5. High-End Performance with Low-End Hardware : Analysis of Massive MIMO Base Station Transceivers
Sammanfattning : Massive MIMO (multiple-input–multiple-output) is a multi-antenna technology for cellular wireless communication, where the base station uses a large number of individually controllable antennas to multiplex users spatially. This technology can provide a high spectral efficiency. LÄS MER
