on to find the best feeding techniques for these antennas. This report aims to study and analyze these antenna miniaturization & feeding techniques. Theory:The most popular technique in reducing the size of a printed antenna is to use a high dielectric constant material for its substrate. In doing so‚ the guided-wavelength underneath the patch is reduced &‚ hence the resonating patch size is also reduced.[1] To further reduce the size‚ slots can be introduced onto the resonating patch.

Mie resonances in dielectric particles can increase the local optical density of states (LDOS) associated with either electric or magnetic transition rates in nearby quantum emitters without ohmic losses. Their rather large quality factors compensate their low field confinement as compared to the plasmon resonances of metallic nanostructures for which nonradiative decay channels dominate. We show theoretically that near-infrared quadrupolar magnetic resonances in silicon particles can preferentially

RENEWABLE ENERGY RESOURCES ABSTRACT The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e.‚ coal‚ petroleum and natural gas) and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy

INTRODUCTION RedTacton is a new Human Area Networking technology that uses the surface of the human body as a safe‚ high speed network transmission path. RedTacton involves initiating communication with a touch that could result in a wide range of actions in response. RedTacton uses the minute electric field emitted on the surface of the human body. Technically‚ it is completely distinct from wireless and infrared. Name of this technology consist of two parts. “Tacton”

The dielectric may be solid or perforated with air spaces. Connections to the ends of coaxial cables are usually made with RF connectors. Radio-grade flexible coaxial cable.

Influences of Fiber Optics Introduction: People have been trying to improve communications over the centuries. Communication plays a very important role in everyday life. The advancement of the world mostly depends on how we share the information with the rest of the world. Fiber optics is making this task easier and quicker. It is currently the fastest internet technology. Fiber optic is a technology of transmitting light through very thin flexible glass or plastic fibers. It is one of the fastest
