A small-size printed antenna is proposed for the application of mobile phones. The antennacomprisesan outer strip, an inner strip, and a common section.It not only occupies a compact area of 25 × 20 mm² butalsosupports two wide bandswithinthe resonantmodes. Prototypes of the antenna had been constructed and experimentally verified. The measured results of the antenna show the bandwidth cover the existing service bands of GSM/DCS/PCS/UMTS within 6 dB return loss specification, and also have good radiation patterns and antenna gains.This antenna is well suitable to be used for mobile phone application.

The analysis and design of a small planar multiband antenna operating in the 4G frequency bands are presented. The numerical and experimental results demonstrated that the proposed antenna satisfies the requirement of 6 dB return loss for the impedance bandwidth of the LTE700/LTE2300/LTE2500 and WiMAX3500 bands. The gains at 750 MHz/2.3 GHz/2.6 GHz/3.5 GHz are 2.1 dBi/4.9 dBi/4.7 dBi/4.3 dBi, respectively. The measured radiation patterns verify the suitability of the antenna to be employed in mobile phones. The dimensions of the radiant patch are 49 × 10 mm2. The proposed antenna can be easily fabricated and customized to various 4G mobile phones as a compact internal antenna.

The new possibilities offered by mobile phones combined with their widespread dissemination among young people open new paradigms for teaching science. The wide adoption of the Java environment for mobile devices gives the opportunity to develop custom-made applications for educational purposes. The first mobile phone application for crystallography training,Escher Mobile, is now available at http://escher.epfl.ch/mobile/.

A compact size on-board printed antenna using capacitive coupled-fed excitation to generate multiple resonant modes for penta-band WWAN operation (GSM850/900/GSM1800/1900/UMTS2100) is presented in this paper. The proposed antenna occupies only a small footprint of 15 × 25 mm2on one corner of the circuit board and a protruded ground of 10 × 15 mm2is displaced with close proximity to the antenna portion. The proposed antenna has a very simple structure which is composed of two separate strips: a loop strip with an inserted chip inductor and an L-shaped feeding strip. The loop strip is shorted to the ground and generates a resonant mode at 890 MHz to cover the GSM850/900 band (824–960 MHz) while the feeding strip contributes to the GSM1800/1900/UMTS210 band (1710–2170 MHz) operation. With such a small size, the proposed antenna can achieve compact integration on the circuit board of the mobile phone, thus the proposed scheme is quite suitable for the slim mobile phone application. Good agreements between simulations and measurements are obtained. Details of proposed antenna are presented and some key parameters are studied.

AbstractWith the advancement in microprocessor technology, mobile phones are becoming more preferable in our day to day lives as compared to personal computers since most phones are capable of functionalities as sophisticated as our PC’s or laptops. Mobile phones nowadays have processor speeds as high as 1GHz and can have a storage capacity of about 32Gb and they also have long hours of battery life. In addition to these feature, there is the aspect of great portability. When all these are combined into one, the mobile phones can be viewed as a very powerful device that rivals PC’s. Advancements of hardware also had made mobile phones much smaller and more efficient whereas including an increasing of peripherals number. The scope of this paper is basically to make a mobile phone application and how to interface the mobile phone to the scanner. The mobile application is to be developed in the Linux-based Android platform. An algorithm based on the operation principles is also to be developed during the work.

A compact wideband printed antenna with deca-band 4G/5G/WLAN for mobile phone devices is proposed in this paper. The complete structure is composed of a monopole antenna and a coupling strip, occupying a small C-shape PCB area of 27 × 10.8 mm2. This antenna, which is printed on FR4 substrate with 0.8 mm thickness and fed by a coaxial cable, can provide three wide operating bandwidths that cover 685–1012 MHz, 1596–2837 MHz, and 3288–3613 MHz for 4G/5G/WLAN communication systems. The gains and total radiation efficiencies of the antenna in the low, middle, and high bands are 1.4 dBi–2.5 dBi and 38%–47%, respectively. Besides, the measured results are in good agreement with the simulated results. Further experiments demonstrate that the proposed antenna exhibits a good performance for mobile phones.

In the present study we link self-report-data on personality to behavior recorded on the mobile phone. This new approach from Psychoinformatics collects data from humans in everyday life. It demonstrates the fruitful collaboration between psychology and computer science, combining Big Data with psychological variables. Given the large number of variables, which can be tracked on a smartphone, the present study focuses on the traditional features of mobile phones – namely incoming and outgoing calls and SMS. We observed N = 49 participants with respect to the telephone/SMS usage via our custom developed mobile phone app for 5 weeks. Extraversion was positively associated with nearly all related telephone call variables. In particular, Extraverts directly reach out to their social network via voice calls.

The purpose of this study is to examine the effect of prestige sensitivity on mobile phone customer’s price acceptance in Vietnam and the mediating role of product knowledge and price mavenism on this relationship. We used the convenience sampling method for data collection via questionnaires with a sample of 605 consumers who purchased mobile phones. The collected data was analysed by applying a structural equation modelling method. The result indicates that prestige sensitivity has both direct and indirect effects on price acceptance via product knowledge and price mavenism. The findings suggest that prestige sensitivity can be used as a market segmentation criterion for mobile phones when making price decisions and providing customers with adequate information could improve price acceptance.
