This research presents a miniaturized Hexangular radiator microstrip line patch at 2.45 and 6.9 GHz Wi-Fi bands for RF Ambient energy exploitation applications. In this research work, an original affordable 1.6 mm thick epoxy-FR4 substrate has been used for the antenna design in Ansys HFSS. The antenna is excited by using the Coplanar Waveguide (CPW) feeding technique. An Etched Ground Plane is used to tune the desired frequency at the backside of the radiating element. The impedance bandwidth can be improved by employing a notch in the ground lane. A rectifier circuit is used to harvest the electromagnetic energy designed to convert the DC output power. The Rectenna design uses a voltage multiplier circuit at the recipient end and output DC voltage is produced. Multisim software is used for designing the Rectenna circuit. The used microstrip patch antenna occupies a size of 80 × 80 × 1.6 mm3. Which provides a Gain of 5.45 dBi and a return loss of −33, and −23 dB respectively. From the source voltage, the result after rectification conversion efficiency is 53% which is quite efficient and they are suitable to overcome the litter bit power crisis for handheld devices.

摘要

This research presents a miniaturized Hexangular radiator microstrip line patch at 2.45 and 6.9 GHz Wi-Fi bands for RF Ambient energy exploitation applications. In this research work, an original affordable 1.6 mm thick epoxy-FR4 substrate has been used for the antenna design in Ansys HFSS. The antenna is excited by using the Coplanar Waveguide (CPW) feeding technique. An Etched Ground Plane is used to tune the desired frequency at the backside of the radiating element. The impedance bandwidth can be improved by employing a notch in the ground lane. A rectifier circuit is used to harvest the electromagnetic energy designed to convert the DC output power. The Rectenna design uses a voltage multiplier circuit at the recipient end and output DC voltage is produced. Multisim software is used for designing the Rectenna circuit. The used microstrip patch antenna occupies a size of 80 × 80 × 1.6 mm3. Which provides a Gain of 5.45 dBi and a return loss of −33, and −23 dB respectively. From the source voltage, the result after rectification conversion efficiency is 53% which is quite efficient and they are suitable to overcome the litter bit power crisis for handheld devices.
