Abstract:
This paper presents a miniaturized Radio Frequency (RF) and microwave energy harvesting system adapted to GSM-900 Network (Global System for Mobile Communication). Most researchers have worked in this domain by trying to harvest an enough DC output voltage to feed different electronic devices to ensure their energy autonomy. The matter with these systems lies in the antenna size. The proposed system is realized on Teflon hybrid technology. The size of the proposed multiband antenna is of 20x30x0.67 mm3, and that of the rectifier matched to the antenna is of 10x15x0.67 mm3. The measurement shows that the antenna is able to cover GSM-900 (935 – 960) MHz, (1470 – 1550) MHz, GSM-1900 (1935 – 1989) MHz and (3 – 3.2) GHz, bands. The output DC (Direct Current) harvested voltage measured is of 0.3 V for 2 kΩ resistance load. This result is sufficient for feeding low power consumption WSNs (Wireless Sensor Networks). In this paper, the selected temperature sensor operates for 0.2 V and 23 nW power supply. The equivalent resistor of this sensor is 2 kΩ. The DC output voltage can reach 0.8 V for the open load.
