Abstract

This research work described in this paper is part of a larger project which aims to develop MEMS/NEMS based miniaturized RF energy scavenging devices. RF energy scavenging holds a promising future for generation of electrical power in order to charge electronics devices. The antenna system, as one of the most important parts in the energy scavenging system, has a significant influence on the overall system efficiency. In this paper, a broadband antenna is designed and modified for an RF energy scavenging system. Simulation results demonstrate that the modified antenna shows a wide bandwidth behavior based on S11 <;-10 dB, covering frequency ranges from 1 GHz to 4.5 GHz. The antenna gain, received power and radiation pattern are also simulated and presented.
