| Summary: | The concept of wireless power transmission was first proposed by Nikola Tesla. He suggested that he could transfer power through the air. The radio waves and microwaves in the air are captured by the antenna and transferred to the destination. The receiver antenna receives the input energy and powers up the system. However, the first rectifying antennas (rectennas) were developed, enabling the conversion of microwave energy into DC power. Rectennas have undergone significant modifications, pushed by the growing demand for Wireless Power transmission and energy generation in many applications, including IoT devices & bio-medical implants. This paper presents the novelty of rectenna design that leverages a planar antenna topology and a high-efficiency rectifier circuit. The design is optimized using a combination of simulation and experimental techniques, significantly improving power conversion efficiency (PCE) and power obtained. The effects of various design parameters, such as antenna geometry, rectifier topology and input power levels, were investigated and optimized for maximum performance. This enhanced rectenna system has a peak power conversion efficiency (PCE) of 70% and a power output of 100 mW, making it compatible for powering low-power electronic devices.
