Five-element inverted-F antenna array for MIMO communications and radio direction finding on mobile terminal
Azremi, Abdullah Al Hadi; Kyro, M.; Ilvonen, J.; Halopainen, J.; Ranvier, S.; Icheln, C.; Vainikainen, P. (Institute of Electrical and Electronics Engineering (IEEE), 2009-12-08)A five-element inverted-F antenna array on mobile terminal for both multiple input multiple output (MIMO) communications and radio direction finding (RDF) applications is presented. The multi-element antenna (MEA) system ... -
On diversity performance of two-element coupling element based antenna structure for mobile terminal
Azremi, Abdullah Al Hadi; Toivanen, J.; Laitinen, J.; Vainikainen, P.; Chen, X.; Jamaly, N.; Carlsson, J.; Kildal, P.-S. (Institute of Electrical and Electronics Engineers (IEEE), 2010-04-12)In wireless communication systems, multipath interference has a significant impact on system design and performance. Fast fading is caused by the coherent summation of one or more echoes from many reflection points reaching ... -
Site-specific evaluation of a MIMO channel capacity for multi-antenna mobile terminals in proximity to a human hand
Azremi, Abdullah Al Hadi; Haneda, K.; Vainikainen, P. (The European Association on Antennas and Propagation (EurAAP), 2011-04-10)This paper presents a comprehensive evaluation on the Multiple-Input Multiple-Output (MIMO) channel capacity performance of a coupling element -based multi-antenna structures on a mobile terminal at the 2000 MHz Universal ...
