SYNOPSIS Title of the project: Wireless Mobile Charger Name of the Guide: Mr. Neeraj Jain

Summary Of Project 1.Introduction: Now a days a mobile phones becoming a basic part of our life .this is one of the most important medium for the communication, the mobile phone batteries has always been problem for recharging. Mobile have to be put to recharge after the batteries has drained out. In this paper the main purpose is shown to make the recharging of mobile phones anywhere you want without charger this is done only when there is a use of microwave, the microwave signal transmitted from transmitter using a special kind of antennas called slotted wave guide antennas at a frequency is 2.45GHZ. We have to add a sensor, rectenna circuit in our mobile phone to do this job successfully. This is one of the best technologies and for this purpose we are proposing wireless charging of mobile phones by using microwaves.

Spectrum of Electromagnetic Radiation

2.Methodology/Procedure/Components required:

2.1 Microwave generator The microwave generator is the one which generates the microwave of preferred frequency. It generates the microwave by the interaction of steam of electrons and magnetic field.

2.2 Transmitting Antenna

There are many types of slotted wave guide antenna available. An electrical current passes through the antenna, inducing a magnetic field, which oscillates at the given frequency. The variations in the current create slight variations in the radio frequency. These radio waves radiate outward from the antenna in a “beam” according to the antenna’s design.

2.3 Rectenna

A rectenna is a rectifying antenna, a special type of antenna that is used to convert microwave energy into direct current electricity. They are used in wireless power transmission system that transmits power by radio waves. In recent years interest has turned to using rectennas as power sources for small wireless microelectronic devices.
