Bundling of handset and subscription is already a widely used concept. This is being done by the mobile operators because they believe that it increase the appeal to the potential end-users. Another concept that is closely related to bundling of handset and subscription is the subsidization of handsets. A handset subsidy allows the end-users to get their handsets at deep discount, or even for f...

In this work numerical simulation and measurements of three-dimensional radiation patterns of a mobile handset model in the presence of a human head phantom were performed at 1800 MHz. Based on theoretical and experimental results, the influence of the human head on the radiation efficiency of the handset has been investigated as a function of the handset size and the distance between the head ...

Abstract—In this paper, the interaction of a planar inverted-F antennas array, mounted on a mobile handset, with a human hand-head phantom is investigated in the 1.9GHz band. The hybrid approach involving the particle swarm optimization (PSO) and Nelder-Mead (NM) algorithm is considered to optimize the complex excitations of the adaptive array elements in a mutual coupling environment for diffe...

A coplanar wave guide (CPW) fed printed monopole antenna with reduced radiation hazard for mobile handset is presented. The antenna offers a bandwidth of 150MHz when printed on a substrate of dielectric constant (εr) 4.4 and thickness 1.6mm with an overall dimension of 0.41λg X 0.31λg.The printed metal strip in the back side of the monopole modifies the radiation pattern suitable for mobile han...

Mobile proximity payment has been discussed for more than a decade, but now it seems close to the maturity and it seems that its mass diffusion has now started. Expectation for Mobile Payment diffusion worldwide is justified by the fact that in 2010 more than three billion people owned a mobile handset [1]. Mobile commerce is a natural successor to electronic commerce. The capability to pay ele...

We are reporting investigations into the interference rejection capabilities of a dual antenna system on a mobile handset prototype for the 1800 MHz band. The performance evaluation is done by using a simulated incoming eld on the handset antennas and by downlink measurements in an indoor environment. Complex signal samples are used in order to investigate the interference rejection gain with d...
