Folded Shorted Patch Antenna with Slots for RF Energy Harvesting in Wireless Sensor Network

There are various types of microstrip antenna that can be used for many applications in communication systems. This paper presents the design of a folded shorted patch antenna FSPA for the application of Radio Frequency RF energy harvesting system capable of receiving radio frequency of GSM 900 band 860MHz to 960MHz . The antenna is designed using microstrip technology on an FR 4 substrate with a dielectric constant of 4.4 and a thickness of 1.6. The antenna was designed and simulated using FEKO, the Electromagnetic solver software. One slot is incorporated into the upper patch of the FSPA. Simulated results show that this antenna can attain an impedance bandwidth of 32MHz from 884MHz to 916MHz at the center frequency of 900MHz with the slot. The results also reveal the good unidirectional radiation pattern and the stable gain over the operating frequency. This antenna is well compatible with using RF energy harvesting to receive the signal of the GSM 900 band.
