On the Practical Design of Small Terminal Antennas for Mobile Applications

Mobile communication have become an important part of telecommunications. Original applications like paging, mobile phones or GPS have shown a tremendous growth, and new applications are emerging every day: tagging, wireless computer links, wireless microphones, remote control, wireless multimedia links, satellite mobile phones, wireless internet. Mobile means light, small, with low energy cons...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Evaluation of Performance of Mobile Terminal Antennas

“the effect of risk aversion on the demand for life insurance: the case of iranian life insurance market”

abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...

Analysis of Mobile Terminal Diversity Antennas

Abstract Antenna diversity has for many years been deployed at the base station to provide significant diversity gain. More recently diversity has also been implemented at the mobile and it has been observed through measurement that antennas still give low correlation even when closely spaced. This paper analyses why de-correlation exists mainly due to angular diversity effects from the two ant...
