| 總結: | 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. |
