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 ...

Effect of heat treatment on Ni-P-Cg(Graphite)-SiC composite coated cast AlSi alloy
(Trans Tech Publications, 2013)
The study presents the effect of heat treatment on electroless N-P-Cg-SiC composite coated cast AlSi (ADC12) alloy. No significant changes are noted on the average surface roughness and surface morphology of the coating ...
Design of a Flexible Minkowski-Like Pre-Fractal (MLPF) antenna with different ground planes for VHF LMR
(City University of Hong Kong, 2011-03-07)
This work investigates the suitability of a flexible Minkowski-like pre-fractal antenna (MLPF) for
application in the Very High Frequency (VHF) Land and Mobile Radio (LMR) frequency bands (136-174 MHz). The
proposed ...
Design and fabrication of a flexible Minkowski fractal antenna for VHF applications
(Institute of Electrical and Electronics Engineers (IEEE), 2011-04-10)
