Design of Multiband Fractal Antenna for Energy Harvesting Applications

currently, significant efforts are being paid on the power management strategies for wireless devices. This leads to exploit the electromagnetic waves that are exist in the ambient environment for battery charging. In this paper, the design of a multi band fractal loop antenna for energy harvesting applications is presented. The proposed antenna has compact dimensions and designed to harvest energy from RF base stations of various mobile networks such as GSM, LTE and the future 5G networks. The resonant frequencies for the proposed antenna is within the range of 900 MHz to 5 GHz. CST Studio Suite software is used to simulate the proposed fractal antenna including the characteristics of S-parameters, gain, and radiation pattern. Simulation results showed that the return loss at resonant frequencies goes below -10 dB, which satisfies the requirements of energy harvesting techniques.
