Final Year Project
Chapter 1 Introduction
1.1 Problem
It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use, you need an efficient way of charging the battery in the phone. But, like most people, you probably don’t like being dependent on the main supply for charging your cell phone battery or you don’t have the time to recharge your cell phone battery. As technology has advanced and made our phones smaller and easier to use, we still have one of the original problems: we must plug the phone into the wall in order to recharge the battery. Most people accept this as something that will never change, so they might as well accept it and carry around either extra batteries with them or a charger. Imagine a system where your cellular phone battery is always charged. No more worrying about forgetting to charge the battery. Sound’s Impossible?
1.2 Objective
The objective of this project is to increase the mobility of cell phones by charging them using the energy present in a part of electromagnetic spectrum, which is present everywhere in the free space, and solar energy without using external AC power source.

1.3 Intended Approach
We have partitioned our project into three phases on the basis of energy types used for charging purpose:
Phase 1 Charging Using Solar Energy In this phase we will design and test the design of solar energy charger, once successfully tested it will be implemented
Phase 2 Charging Using EM Waves In this phase we will design and test the design of EM Wave energy charger, once successfully tested it will be implemented.
Phase 3 Combinations of the Two Charging Systems After successful completion of phase1 and phase2, both systems will be incorporated in a single unit to build an efficient and powerful charger.

Background
This project is based on a very simple concept, capture RF energy using an antenna, input it into a RF Transformer and use this energy to power
