Dual-Band Single-Layered Modified E-shaped Patch Antenna for RF Energy Harvesting Systems

摘要

Radio Frequency Energy Harvesting (RF EH) is an alternative, yet well-promising technique to deliver power in electronic circuits of wireless sensor networks that require small amounts of energy. The design of the receiving module (antenna) in RF EH systems is a demanding and, in most cases, a complex task. As a result, an optimization method is often required. In this paper, we apply The Salp Swarm Algorithm to design and optimize a receiving module (dual-band modified E-shaped antenna) for RF EH systems. The proposed antenna operates in the frequency bands of LTE-2600 and 5G NR mobile communication networks. Numerical results exhibit a satisfactory operation of the optimized antenna as a receiving module in an RF EH system.
