Wi-Fi sources can be found in almost all establishments nowadays, even on transportation vehicles, malls, houses. Your phones and laptops can detect Wi-Fi sources almost everywhere. The researchers maximized this opportunity to contribute to the already existing body of knowledge about harvesting energy and convert it to other forms of useable energy. In this case, the researchers focused on harvesting a frequency in the range of 2.4GHz. This thesis paper is about how the researchers designed and experimented using two antennas (one omnidirectional and one unidirectional antenna) and a rectifier with a 3pF capacitor and two different diodes (HSMS 2820 and HSMS 2860) to harvest a signal from a Wi-Fi source (router), and convert this signal to a DC voltage. The researchers also experimented to know how large or how small the voltage their rectenna device will be able to produce to know which applications this study can be applied on. Through the researchers experiment, it can be concluded that it is possible to harvest a Wi-Fi signal, although the voltage converted was small. Hence, this thesis can be applied to low power or low voltage applications.
