“…Syarat yang penting pada suatu sistem RF-Energy harvester yakni ukuran yang compact, mudah diintegrasikan, portable dan lainnya. Syarat lainnya yakni gain yang tinggi sehingga dapat menyerap gelombang elektromagnetik dengan maksimal dan efisiensi antena yang tinggi (Divakaran, 2017). Setelah proses simulasi dan fabrikasi antena mikrostrip patch double-T berbasis metamaterial CSRR, maka perlu dilakukan pengujian untuk menilai parameter performansi perancangan suatu antena.…”

Kemandirian energi dan long battery lifetime merupakan visi teknologi 5G salah satunya untuk perangkat cerdas IoT. Output dari metode hybrid energy harvester sebagai salah satu solusi dari kemandirian energi menggunakan gelombang frekuensi radio (RF) telah dioptimasi pada penelitian ini. Antena mikrostrip patch double-T berbasis metamaterial CSRR sebagai pemanen energi RF bekerja pada frekuensi ISM band 2.45 GHz memiliki nilai return loss, gain dan bandwitdh yang sudah sesuai untuk konsep sistem RF-Energy harvester. Antena ini mampu menyerap energi menggunakan rangkaian konverter DC pada jarak terdekat maksimum sebesar 6.79 V menggunakan 2 buah access point pada posisi antena pemancar saling berhadapan satu sama lain dengan efisiensi konversi 6.68%. Salah satu metode untuk memaksimalkan output energy harvester juga dilakukan pada penelitian ini dengan melakukan hybrid dengan mini solar cell, yang mampu menyuplai tegangan secara konstant dan dapat melakukan charging terhadap beban berupa handphone. Sistem hybrid RF-Energy harvester yang dirancang pada penelitian ini sudah dapat berfungsi sebagamana tujuan dari penelitian dilakukan yakni untuk sumber energi perangkat cerdas dengan kebutuhan daya kecil.

“…Furthermore, the antenna must possess high gain in order to enable the reception of available energy, and it must also possess high efficiency so that losses can be minimized [8]. Several studies have reported the harvesting of RF power from a single frequency band [8][9][10]. If the usable power range is low, a minimum output capacity is provided.…”

The investigation into new sources of energy with the highest efficiency which are derived from existing energy sources is a significant research area and is attracting a great deal of interest. Radio frequency (RF) energy harvesting is a promising alternative for obtaining energy for wireless devices directly from RF energy sources in the environment. An overview of the energy harvesting concept will be discussed in detail in this paper. Energy harvesting is a very promising method for the development of self-powered electronics. Many applications, such as the Internet of Things (IoT), smart environments, the military or agricultural monitoring depend on the use of sensor networks which require a large variety of small and scattered devices. The low-power operation of such distributed devices requires wireless energy to be obtained from their surroundings in order to achieve safe, self-sufficient and maintenance-free systems. The energy harvesting circuit is known to be an interface between piezoelectric and electro-strictive loads. A modern view of circuitry for energy harvesting is based on power conditioning principles that also involve AC-to-DC conversion and voltage regulation. Throughout the field of energy conversion, energy harvesting circuits often impose electric boundaries for devices, which are important for maximizing the energy that is harvested. The power conversion efficiency (PCE) is described as the ratio between the rectifier’s output DC power and the antenna-based RF-input power (before its passage through the corresponding network).
