On prediction of MIMO capacity performance with antenna magnitude patterns

På svenska

Author

Summary, in English

This paper considers the impact of phaseless (or magnitude only) output antenna patterns on the performance of multiple antenna systems which employ impedance matching networks. In particular, correlation and capacity are used as performance metrics when the output patterns are with or without phase information. Two methods of synthesizing complex antenna patterns are also discussed and their performances are evaluated. Results show the significance of having phase information on output antenna patterns when evaluating MIMO performance. Adding random phases to phaseless output patterns tends to overestimate the capacity performance, whereas adding synthesized phases according to antenna spacings underestimates capacity.
