in this paper, a design of a new E-shape fractal antenna for multistandard application is proposed. Fractal geometry is best suited for its self similarity and space filling characteristics. An optimized design of fourth iteration of E-shape fractal is designed to satisfy the higher multistandard mobile terminal application. Various mobile standards are obtained at the end of iteration in parti...

A novel monopole internal antenna for mobile handsets is presented. The antenna, called the MB antenna, is a modified monopole whose radiating element is implemented in parallel proximity of a ground plane hence allowing for use as an internal antenna in handset applications. Simulation studies indicate that the proposed MB antenna has superior performance over PIFA antennas commonly used in mo...

Mobile Ad hoc Networks (MANETs) have drawn considerable attentions of the researchers for the last few years. MANETs, consisting of mobile nodes, are self-organizing and self-configuring and hence can be deployed without any infrastructure support. MANETs also have some limitations including short-life, unreliability, scalability, latency, high interference, and limited resources. In order to o...

Introduction: In recent years, the rapidly increasing use of mobile phone operating nearby the human head has caused public concern for its effects on human health. The FDTD methodology is widely used for calculation of the effects of electromagnetic fields on human body. Methods and Materials: In this paper, first a dual band patch antenna structure (GSM-900 and DCS 1800), which is located i...

A planar, printed multiple-input multiple-output (MIMO) antenna for slim mobile handset is presented. The dual-antenna system, comprises two symmetric antenna elements, is printed on a printed circuit board (PCB) of mobile phone. Each antenna element consists of coupled-fed loop antenna. The loop antenna is formed by a quarter wavelength (at 762MHz) meandered loop strip with end terminal short-...

Yoshiki Okano and Keizo Cho We have developed an antenna measurement system for mobile terminals that can efficiently evaluate both the performance of the mobile terminal antenna itself and the overall radio performance of the mobile terminal. We provide an overview of that measurement system and describe the technology applied for faster and more accurate measurement as well as the effectivene...
