Low-Profile Circularly Polarized Rectifying Antenna for Wireless Power Transmission at 5.8 GHz
Abstract
Portable devices operating without batteries aresometimes desired in wireless applications such as RFID (RadioFrequency Identification) and telemetry. A novel circularlypolarized shorted annular ring-slot rectenna (rectifying antenna)on a 0.5 mm thick flexible microwave laminate is proposed for thepowering of these devices. Output dc voltage of 1.3 V and axialratio of 1.5 dB were measured when 32 dBm microwave powerwas transmitted a ....etc

SMART ANTENNA DESIGN FOR WIRELESS COMMUNICATION USING ADAPTIVE BEAM-FORMING APPROACH




INTRODUCTION


The dramatic growth of the wireless communication industry has resulted in searches for new technologies to provide broader bandwidth per user channel, better quality, and new value-added services.
Due to drastical increase in wireless communication system, it is necessary to increase the Data Transmission Speed and Coverage Area.

Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc

Abstract

The main scope of the project is to control the Dish antenna from a remote area.
Stepper motors operate differently from normal DC motors, which rotate when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple toothed electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit, such as a microcontroller.
To make the motor shaft turn, first one electromagnet is given power, which makes the gear's teeth ....etc

ABSTRACT

This paper presents a scheme for designing a kind of wireless charging system aimed to provide power transmission for personal mobile devices such as cell phone. This scheme consists of three parts: wireless power transmission design, wireless signal transmission design and charging manage design. A circular array consisting of some antenna elements is employed in the scheme as transmit access of power and signal. In the supposed indoor condition, the transfer efficiency can up to 66%. The charging manage adopt a close-loop optimal ....etc
