Site-specific evaluation of a MIMO channel capacity for multi-antenna mobile terminals in proximity to a human hand
(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 ...
Ambiguity analysis of isolation - Based multi-antenna structures on mobile terminal
(Institute of Electrical and Electronics Engineering (IEEE), 2011-04-10)
This paper presents a comprehensive numerical study on the ambiguities for different isolation-based multi-antenna structures. The focus is on four-element planar inverted-F antennas (PIFA) array on a typical 100mm 40mm ...
Parametric studies of the pyramidal microwave absorber using rice husk
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Agriculture waste has potential to be used as an alternative material for the microwave absorber used in the anechoic chamber. Compared to the current materials used, such as polystyrene and polyurethane, agricultural waste ...
Reflection loss performance of hexagonal base pyramid microwave absorber using different agricultural waste material
(Institute of Electrical and Electronics Engineers (IEEE), 2010-11-08)
Hexagonal base pyramid microwave absorber is the new design of microwave absorber. In this work, two sub-shapes are considered to compare it reflection loss performance. The shapes are hexagonal and truncated hexagonal ...
Microwave wedge absorber design using rice husk - An evaluation on placement variation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-04-12)
Placement variation is one example of parameters
that critically affects the performance of RF absorbers. In this
work, four designed variation patterns - W, X, Y, and Z were
discussed to compare the reflectivity (Sll) ...
Rubber tire dust-rice husk pyramidal microwave absorber
(EMW Publishing, 2011)
Rubber tire dust-rice husk is an innovation in improving the design of pyramidal microwave absorbers to be used in radio frequency (RF) anechoic chambers. An RF anechoic chamber is a shielded room covered with absorbers ...
Influence of the user's hand on mutual coupling of dual-antenna structures on mobile terminal
(Institute of Electrical and Electronics Engineers (IEEE), 2012-03-26)
This paper studies the influence of the user's hand on the mutual coupling of dual-antenna structures on a mobile terminal. The terminal consists of two planar inverted-F antennas (PIFA) on a typical 100 × 40 mm 2 mobile ...
On diversity performance of two-element coupling element based antenna structure for mobile terminal
(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 ...
Multi-antenna mobile terminal diversity performance in proximity to human hands under different propagation environment conditions
(The Institution of Engineering and Technology, 2011-10-27)
The effective diversity gain (EDG) of a four-element planar inverted-F antenna array, which operates at 3500MHz in the proximity to one hand in data-mode grip and two hands in browsing-mode grip, is predicted using a ...
