Purpose: This study seeks to enhance voltage multipliers for Radio Frequency (RF) energy harvesting, with an emphasis on increasing the efficiency of harvested energy. improvement is vital sustainable applications and reducing environmental pollution caused by fossil fuels. Theoretical reference: RF harvesting technology gaining recognition as a viable method capturing ambient energy, earlier research primarily focused antenna circuit design. Nonetheless, effectiveness still constrained inadequate power output. expands prior directly comparing two commonly utilized multipliers, Cockcroft Walton Dickson in context harvesting. Method: The were optimally designed using Multisim their performance was analysed MATLAB. comparison conducted at input 1V within frequency ranges: 85 MHz – 110 (FM band) 1.8 GHz 3.0 (4G band). Output voltages both recorded compared across these bands. Results Conclusion: At FM band (85 MHz), multiplier outperformed multiplier, delivering output 11.1V 6.6V. However, 4G (1.8 GHz), more effective, providing maximum 5.2V against Dickson's 4.1V. concludes that suitable from band, while better Implications research: findings suggest different may benefit distinct depending question. could guide design efficient circuits future technologies aimed solutions. Originality/value: offers direct under conditions, valuable insights into optimizing green applications. results help advance understanding specific bands, contributing development effective systems.
