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 ...
Design and measurement-based evaluation of multi-antenna mobile terminals for LTE 3500MHz band
(EMW Publishing, 2013)
Design of multi-element antennas (MA) for small mobile terminals operating at higher frequencies remains challenging despite smaller antenna dimension and possibility of achieving electrically large separation between them. ...
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 ...
