Design of a dual band rectifier circuit for drone powering applications

Abstract

Wireless Power Transmission has seen a significant amount of growth in the previous decade. One of the significant application scenarios is the powering of multicopter flying devices. The main reason behind this utility is the ability of the modern circuits to transmit power content at high frequencies. In the proposed design a Dual-Band Rectifier has been developed for 2.1 GHz and 2.45 GHz frequencies. The circuit uses Schottky Diode HSMS-285C as the rectification diode. The rectifier circuit used here is a Greinacher Voltage Doubler. Impedance Matching of the rectifier has been carried out to improve its performance. Results consisting of the output voltages and conversion efficiencies have been plotted for both the frequencies from 0 to 10 dBm of input power. At 2.1 GHz, maximum conversion efficiency of 67.263 % is obtained whereas for 2.45 GHz, maximum value of 51.471 % is observed. All Simulations have been carried out on the Advanced Design System (ADS) Software and final circuit has been fabricated on Proteus Design Suite. The purpose of this design is to fulfill drone powering requirements with enhanced efficiencies and commercial viability in comparison to the contemporary circuits. It can be used in the form of a rectenna circuit in order to provide an efficient multiplying system for drone simulation and improve the device's performance.
