N2  - Radio Frequency Identification (RFID) is a wireless communication technology that enables users to uniquely identify tagged objects or people via radio frequency waves. Active RFID tag has an onboard battery to power the tag which allows greater capability compared to passive tags. However, onboard batteries have limited lifespan and replacement of batteries can be time-consuming and costly. A solution to battery replacement would be to harvest ambient RF energy to prolong the battery life of the active RFID tag. The aim of this research is to harvest energy from WiFi signals using rectenna architecture which consists of a receiving antenna attached to a rectifying circuit that efficiently converts RF energy to DC current. Harvested power will be in the order of microwatt range and utilization of harvested power has to be specific for applications with low power consumption. © 2012 IFSA.
