Abstract: In today’s modern era, mobile phones have become a basic need for people all over the world. The charging of mobile phone has become an arduous task. It is a hectic task to carry everywhere the charger of mobile phones or any electronic gadget while travelling or it is very cruel when your mobile phone getting off by the time you urgently need it. It is the major problem in today’s electronic gadgets. Though the world is leading with the developments in technology, but this technology is still incomplete because of certain limitations. Today’s world requires the complete technology and this purpose is solved using a technique called ‘Wireless Charging of Mobile Phones Using Microwaves’.
INTRODUCTION
BASIC CONCEPTS:-
The technique mentioned has two basic concepts. They are:-
Electromagnetic spectrum
Microwave region
ELECTROMAGNETIC SPECTRUM:-
When white light is shone through a prism it is separated out into all the colors of the rainbow this is called the visible spectrum. According to some physicians light consists of tiny particles called photons. Photons are bundle of energy. The speed of light is about 300,000,000 meters per second as light hit something that means it may be bounce off, go right through or get absorbed. If they bounce off something and then go into your eye you will see the thing they have bounced off. This is the cause of vision.
MICROWAVE REGION:-
Microwaves are a form of electromagnetic radiation with wavelengths ranging from as long as one meter to as short as one millimeter, or equivalently, with frequencies between 300 MHz (0.3 GHz) and 300 GHz. Microwave technology is extensively used for point-to-point telecommunications (i.e., non broadcast uses). Microwaves are especially suitable for this use since they are more easily focused into narrower beams than radio waves, allowing frequency reuse; their comparatively higher frequencies allow
