Abstract

The solar energy received by the solar cells satellite in space produced electricity. Then the electricity will be converted into microwave signal. The microwave signal will be transmitted by the satellite's transmitter, wirelessly and received by the rectifying antenna or known as 'rectenna' on the Earth. Rectenna acts as microwave receiver and a converter of microwave signal into DC power. This system is known as Wireless Power Transmission system (WPT). The frequency for the rectenna element is 2.45 GHz. Nevertheless, the simulations and analysis concentrate only on power rectangular microstrip patch antenna (RMPA) and Schottky diode using Microwave Office 2004 simulation. In reality the achieved of the transmitted power is merely at 0.9% bandwidth. Thus, to improve it to more than 0.9% of bandwidth, a research on dielectric substrate is required. The design of the rectenna is also crucial so that the 0.9% of bandwidth or more can be achieved. By using this simulator, the performances of these two elements can be obtained. Based on the results, the PTFE/Glass mix dielectric substrate offered better performance than the other dielectric substrate, producing 1.84% of antenna bandwidth. For the Schottky diode, the total power that has been successfully analyzed is at 1769923.5 mW. The diode conversion efficiency has been evaluated as 44.375%. This project covers chapter 1, for introduction, chapter 2 for literature review, chapter 3 for methodology, chapter 4 for results and discussions and chapter 5 for conclusion and recommendation. Overall, the simulations have been successful, thus the objectives of the project are achieved.
