Novel optimized U-slot Folded Shorted Patch Antenna (FSPA) is proposed and designed in this paper for the application of Radio Frequency ( RF )-harvesting antenna capable of receiving radio frequency of GSM-900 band (860MHz – 960 MHz) . The antenna simulation software, Computer Simulation Technology (CST) microwave studio 2012 is used for designing and performing the simulation of the proposed antenna. One U-slot is incorporated into the upper patch of the FSPA. Simulated results show that this antenna can attain an impedance bandwidth of 17.73% from 839 MHz to 995 MHz at the centre frequency of 880MHz. The results also reveal the good unidirectional radiation pattern and the stable gain over the operating frequencies. It is attained from the simulation outcome that this antenna is well compatible for using in RF energy harvesting to receive signal of GSM-900 band.
