SPECIFICATIONS AND DELIVERABLES OF THE PROJECT
BLOCK DIAGRAM
To develop a device that can charge mobile devices wirelessly up to a range of
2-3m
, irrespective of their power requirements
METHODOLOGY
SCOPE
APPLICATIONS

1. Designing of Antennas
2. Transmitter and Receiver system designing
3. Hardware Implementation
4. Testing
5. End Product

The device will be charged even if it is in the hand or pocket of a person. We are increasing the distance of charging from a few millimeters as done in the past to meters range.

The transmitter will remain fixed while the receiver will be attached to the mobile device.

Radio frequency communication in the microwave S-band.

It can be placed in homes.

It can be placed inside restaurants and cafes.

It can be used in offices and organizations.

It can be used in a car to charge devices.

The deliverables will include a transmitter which can be mounted on the wall of the room, just like a wifi router. It will transmit the electromagnetic waves. The receiver will be placed in between the battery and the back cover of the mobile device. It will receive the electromagnetic waves to charge the mobile device. The distance between the transmitter and the receiver will be within few meters giving the person freedom to place the mobile anywhere or use it while it is getting charged.
