摘要： In this research, the design and optimization of a novel leaf-shaped antenna inspired by natural leaf structures for radio frequency energy transfer is presented. The objectives of this study are to develop a bio-inspired antenna, optimize its performance through impedance matching for the 915 MHz frequency band, and evaluate its efficiency in capturing RF energy. The design process involves selecting an appropriate leaf shape, modeling the antenna using AutoCAD and HFSS software, and fabricating a printed circuit board (PCB) prototype. Simulations and physical tests are conducted to optimize the antennas performance, achieving an S11 parameter of nearly -20 dB at 915 MHz, indicating effective energy capture. Experimental results demonstrate the antennas ability to power a device at distances up to 200 cm, with charging times reflecting its efficiency. The study concludes that the bio-inspired design of the proposed antenna improves RF energy transfer. Future work should focus on testing the antennas penetration through concrete and developing a feedback system for autonomous alignment.
