Abstract
Perkembangan teknologi nirkabel yang pesat menghasilkan kelimpahan sinyal Radio Frequency (RF) di lingkungan, khususnya pada pita frekuensi Radio Local Area Network (RLAN) 2,45 GHz dan 5 GHz, yang energinya seringkali tidak termanfaatkan. Penelitian ini bertujuan untuk mengimplementasikan RF Energy Harvesting pada frekuensi RLAN khususnya dalam merancang dan membuat rectifier antena yang dapat digunakan untuk mendukung perangkat berdaya rendah seperti Light Emitting Diode (LED). Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model V-Model yang mencakup tahap perancangan dan simulasi rangkaian rectifier pengganda tegangan menggunakan software Advanced Design System (ADS), fabrikasi dilakukan pada substrat Printed Circuit Board (PCB) FR-4 dengan konstanta dielektrik (εr) = 4,4, ketebalan (h) = 1,6 mm, dan loss tangent (tan δ) = 0,022, serta pengujian. Hasil simulasi menunjukkan rangkaian berhasil mencapai tegangan keluaran 2,302 V pada daya masukan 7 dBm dengan return loss sebesar -17,01 dB pada frekuensi 2,45 GHz dan -14,56 dB pada frekuensi 5 GHz. Pada tahap pengujian, prototipe yang telah difabrikasi mampu menghasilkan tegangan maksimum 1,93 V saat berada pada jarak 0 cm dari sumber perangkat yang memancarkan sinyal RF pada frekuensi 2,45 GHz dan 5 GHz yaitu access point Wireless Fidelity (Wi-Fi), yang energinya kemudian dipanen oleh prototipe, yang terbukti berhasil menyalakan LED. Kesimpulannya prototipe ini berhasil memanen energi RF untuk aplikasi berdaya rendah, meskipun terdapat perbedaan signifikan antara hasil simulasi dan pengukuran yang disebabkan oleh faktor non-ideal seperti toleransi komponen, ketidaksempurnaan fabrikasi, dan kerugian pada saat pengukuran. ***** The rapid development of wireless technology has led to an abundance of Radio Frequency (RF) signals in the environment, particularly in the Radio Local Area Network (RLAN) frequency bands (2.45 GHz and 5 GHz), whose energy often goes unutilized. This research aims to design, build, and test an RF Energy Harvesting prototype capable of converting energy from RF signals into electrical power to supply low-power devices such as a Light Emitting Diode (LED). The research method used is Research and Development (R&D) with a V-model, which includes the design and simulation of a voltage doubler rectifier circuit using Advanced Design System (ADS) software, Fabrication was performed on an FR-4 Printed Circuit Board (PCB) substrate with a dielectric constant (εr) of 4.4, a thickness (h) of 1.6 mm, and a loss tangent (tan δ) of 0.022, and empirical testing. Simulation results show that the circuit successfully achieved an output voltage of 2.302 V at an input power of 7 dBm, with a return loss of -17.01 dB at 2.45 GHz and -14.56 dB at 5 GHz. During testing, the fabricated prototype successfully harvested energy from a Wireless Fidelity (Wi-Fi) access point, which was emitting RF signals at 2.45 GHz and 5 GHz. When placed at a contact distance (0 cm) from the source, the prototype generated a maximum voltage of 1.93 V, which was sufficient to power an LED. In conclusion this prototype successfully harvests RF energy for low-power applications, although there is a significant discrepancy between the simulation and measurement results due to non-ideal factors such as component tolerances, fabrication imperfections, and measurement losses.
