1. 1. Multiport Antenna Systems for Space-Time Wireless Communications

   Författare :Nima Jamaly; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spatial Correlation; Multiport Matching Efficiency; Multiport Antennas; Uncorrelated Multipath.; Richness Threshold; Multiport Effective Length; Pattern Overlap Matrix; Multiport Effective Area; Non-rich Multipath; Covariance Matrix; Predictor Antenna System; Correlated Multipath;

   Sammanfattning : Multiport antenna systems are indispensable part of modern wireless communication systems. Their crucial impact on the overall performance requires sufficient regard and dedication to a precise design and characterisation. This concern has been to a considerable extent addressed in the frame of the current thesis. LÄS MER

3. 2. Optimal Near-field Antenna Apertures in Lossy Media

   Författare :Aidin Razavi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal near-field aperture; near-field focusing; near-field antennas; near-field power transfer; array signal processing.; maximum penetration;

   Sammanfattning : Antennas are traditionally designed for far-field applications such as wireless communications, radar, etc., where the antenna systems interact with other systems and objects which are located in the far-field zone of the antennas. LÄS MER
