Abstract

Pengoperasian sistem Wireless Sensor Network (WSN) yang masih bergantung pada baterai menimbulkan permasalahan efisiensi energi, biaya operasional tinggi, dan kebutuhan perawatan rutin. Salah satu solusi alternatif yang menjanjikan adalah Radio Frequency Energy Harvesting (RFEH), karena ketersediaan sumber daya RF yang melimpah dan selalu tersedia, seperti sinyal seluler LTE1800 MHz, LTE2100 MHz, dan WiFi 2400 MHz. Namun, RFEH memiliki tantangan pada rendahnya daya yang dihasilkan.Penelitian ini bertujuan untuk merancang sistem rectenna yang terdiri dari antena dual-log periodic dan multiband rectifier untuk meningkatkan penerimaan daya dari berbagai sumber frekuensi RF. Antena dirancang agar bersifat omnidireksional dan memiliki karakteristik wideband, sehingga mampu menerima sinyal dari berbagai arah dalam rentang frekuensi 1700–2400 MHz. Pengujian dilakukan dengan mengintegrasikan antena dengan rangkaian voltage doubler rectifier multiband yang dioptimalkan pada frekuensi 1700 MHz, 1900 MHz, dan 2400 MHz menyesuaikan hasil daya frekuensi yang tersedia di sekitar antena.Hasil pengujian menunjukkan bahwa desain rectenna mampu menerima sinyal RF pada ketiga frekuensi tersebut dengan daya keluaran sebesar 4,4 pW dan tegangan sebesar 36 µV. Dengan demikian, sistem ini menunjukkan potensi untuk diaplikasikan sebagai solusi penyedia daya alternatif pada WSN berbasis RFEH.

The operation of Wireless Sensor Networks (WSNs) still heavily relies on batteries, leading to high operational costs and maintenance requirements. One promising alternative is Radio Frequency Energy Harvesting (RFEH), which utilizes the abundant and continuously available RF energy sources such as cellular signals at LTE1800 MHz, LTE2100 MHz, dan WiFi 2400 MHz. However, RFEH faces a major limitation in the form of low power output.
This research aims to design a rectenna system consisting of a dual-log periodic antenna and a multiband rectifier to improve power reception from multiple RF sources. The antenna is designed to be omnidirectional and wideband, enabling it to receive signals from various directions within the 1700–2400 MHz frequency range. Testing was conducted by integrating the antenna with a multiband voltage doubler rectifier circuit optimized for 1700 MHz, 1900 MHz, and 2400 MHz consider the harvested energy from the antenna.
The experimental results show that the rectenna design successfully received RF signals at the specified frequencies, producing an output power of 4.4 pW and a voltage of 36 µV. These results indicate that the proposed system has potential as an alternative power source solution for WSNs based on RFEH technology.
