Wireless Power Transmission (WPT), Electromagnetic Energy Harvesting (EEH), and Passive Radio Frequency Identification (RFID) are the concurrent technologies in the Internet of Things era. In the idea to preserve the totally passive devices, EEH is the best solution where the Rectenna can convert this electromagnetic energy for the battery-less devices and its attached sensors. Most of the Rectenna are designed at ISM, GSM and UMTS band frequencies. The objective is to wirelessly gather energy from one RF source and convert it into usable DC power that is further applied to a set of low power electronic devices. Radio Frequency Identification (RFID) tag system could also be improved using this method. RF-to-DC conversion is accomplished by designing and characterizing an element commonly known as a Rectenna, which consists of an antenna and an associated rectification circuitry. This work presented here explains the step by step approach for the Energy harvesting for RFID working in ISM 2.4 GHz and a rectifier circuit. Thus, the main objective is to the design an antenna, to harvest the electromagnetic energy at the desired frequency thereby increasing the gain of the antenna and the overall conversion efficiency. In the first phase, single band single patch rectangular microstrip antenna and broadside array of 4 elements are designed that operate in 2.45 GHz band. They are a single band single feed antenna that provide excellent frequency response and fairly omni-directional radiation pattern. In the second phase, rectenna design is carried out to convert received RF power into DC voltage. Impedance matching and power combining included in the circuit here ensures maximum power transfer to the passive RFID chip and the rectifying circuitry. Non-linear effects of the rectifier element are also studied and included in the co-simulation. Third phase consists of co-simulation to mitigate any integration issues of first and second phase. The sufficient isolation is provided at the frequency to support harvesting from the 2.45 GHz band.
