Abstract

Limited life span of the battery usually limits the operating time of the devices in wireless sensor network (WSN). Although solar energy harvesting could be one of the ways to solve the problem, but due to the blackout period and weather problem, it becomes not practical. Therefore, Radio Frequency (RF) energy harvesting can be an alternative to solve this problem. Nowadays, there are a lot of wireless communication network exists in the world such as mobile network, WiFi and satellite communication network. RF energy is one of the energy sources where it is essentially inexhaustible. It is time independent and a kind of easily obtained energy source. RF energy harvesting system can be used to convert the RF energy to an amount of electrical energy that is possible to power up an application in wireless sensor network. RF energy harvesting system makes wireless sensor network becomes more practical in cost, size and lifespan. In this project, an RF energy harvesting system that is operating at 915MHz is designed. With the use of direct RF input, 50.42% of power conversion efficiency at -5dBm is achieved. On the other hand, with the use of receiving antenna, 23.06% of the power conversion efficiency at -5dBm is achieved as well. The RF energy harvesting system is designed by using the Advanced Design System (ADS) software. Then, the layout design of the RF energy harvesting system is design by using the Momentum Software. The process is followed by developing the harvester by using off the shelf components. Lastly, the overall simulation result and the experimental result has been recorded, analyzed and discussed clearly as well.
