Mobile Handset Performance Evaluation Using Spherical Measurements
The mean effective gain (MEG) is an attractive performance measure of mobile handsets, since it incorporates both directional and polarization properties of the handset and environment. In this work the MEG is computed from measured spherical radiation patterns of five different mobile handsets, both in free space and including a human head & shoulder phantom. Different models of the environmen...
متن کاملModified CPW Fed Monopole Antenna with Suitable Radiation Pattern for Mobile Handset
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...
متن کاملInfluence of Spherical Radiation Pattern Measurement Uncertainty on Handset Performance Measures
An important characteristic of a mobile handset is its ability to receive and transmit power. One way to characterize the performance of a handset in this respect is to use measurements of the spherical radiation pattern from which the total radiated power (TRP), total isotropic sensitivity (TIS), and mean effective gain (MEG) can be computed. Often this kind of measurements are made with a pha...
متن کاملFast Measurement of Radiation Efficiency of Mobile Handset Antennas
A simultaneous measurement method using parallel modulated probe array has been proposed to measure the electromagnetic radiation rapidly. Each modulated probe is excited by a local signal with individual frequency, so that the received IF signal contains different frequency components which indicate the relative magnitude of the RF signal at positions of the probes, and all the IF components a...
متن کاملFactors Affecting Mobile Handset (MH) Buying Decision: An Empirical Study
Mobile technology is getting changed very fast in commensurate with other technological hyper changes. Buyers’ expectation from a new cellular phone is also changing over time. Producers, thereby, have to keep themselves abreast of changes in customer taste and preferences to attract, capture, grow, and retain both existing and potential customers. This study is set to measure factors affecting...
