| Summary: | Wireless technology is going through expansive research and development. Thus the antenna design should be further innovated as it is the fundamental of wireless system. The integration between the antennas with other element are needed to create more functional variation of the antenna. Antenna with Light Emitting Diode (LED) is introduced to create dual functional antenna, where antenna itself which can transmit and receive signal and as light source at the same time. As government has launched Green Building Index which is a subset of National Green Technology Policy, LED is a part of transforming to more efficient lighting source in energy utilisation category. Thus, this creates opportunity to present LED integrated antenna as'. a further innovation of antenna and lighting and as one of the solution for a green technology. The research described in this thesis focuses on the development of the integration between Monopole Microstrip Patch Antenna with Light Emitting Diode (LED) and to investigate the effect of Light Emitting Diode to the antenna performance. In this project, two designs of the integration between antennas with LED were proposed. Design 1 is the starting point to understand the effects of adding LED to the antenna. In Design 1, the monopole antenna at 3.6GHz and 5 LED is added in series circuit to increase the length of the antenna. The fabrication results shows that, when there is no LED is added into the antenna structure, the frequency is at 3.693 GHz with the value of Sl 1 is -27.95 dB. After 5 LED is integrated with the monopole, the frequency change to 1.608 GHz with Sl 1 is -16.32 dB. The result shows that as the length of the antenna increase, the frequency will go inversely proportional. |
