=Introduction=

Wireless charging technology is becoming increasingly popular and is often used to charge batteries in smart phones, smart watches and other devices. A wireless charging system uses a rectenna system along with a power management circuit. A rectenna system consists of a receiving antenna and a rectifier circuit that is used to convert microwave or RF energy from ambient sources into useful DC power.

=Problem Description=

In this project you will design, fabricate and test a rectenna system that would be useful to charge lithium-ion batteries in old flip type cellular phones (Nokia, Motorola, etc).

=Conceive=

The CL-158 laboratory room may have a WiFi router or similar equipment that may broadcast or transmit RF power and use it as RF power source for rectenna system.

=Design=

As a starting point for your project, you may use a mono-pole antenna such as a "whip" antenna as receiving antenna. You may develop with the help of class instructor a Schottky diode rectifier circuit or a charge pump circuit (Schottky diode voltage doubler circuit) that can be used with a "whip" antenna in the rectenna system. The rectenna system will convert RF power into DC power needed for charging lithium-ion batteries of cellular phones.

=Implement=
 * 1) /Develop a block diagram for rectenna system and determine the scope of the project/
 * 2) /Develop a list of tasks/
 * 3) /Assign tasks among team members of project/
 * 4) /Parts list, Equipment list and Budget/
 * 5) /Prepare a schedule for hardware and software development and testing/
 * 6) /Milestones and Deliverables/
 * 7) /Develop a short proposal with an abstract for the project should cover the six items listed above/
 * 8) /Prepare a design review documents (preliminary design review - PDR presentation on Oct 14; critical design review - CDR presentation on Nov 11)/

=Operate= Complete the tasks assigned to each team member of the project as per schedule decided between team members and class instructor. Record project work details in project notebook and prepare weekly progress report of the project and submit to class instructor. Evaluate progress on project with class instructor. Work systematically on project deliverables and achieving milestones of project.

=Demo= Each team is expected to prepare a presentation and demonstration of the project to general public who will attend the project day. =Next Steps=
