Starting from the year 2000, metamaterial structure has been one of the favorite techniques used by several researchers to improve the performance of many radio frequency (RF) device designs, especially in the microwave range area. Wireless charging technologies that have emerged are also one of the highlighted discussions among users, fabricators and researchers. This paper presents a literature review of radio frequency energy harvesting, using a split ring resonator (SRR) and other metamaterial structure in antenna network applications. The objective of this paper is to define and compare the several performances such as the technique used, the material of the substrate, dimension, return loss and the resonant frequency of the antenna. The split ring resonator is an interesting metamaterial structure, that is applied in several researcher's work compared with other metamaterial structure such as electronic band gap (EBG), photonic band gap (PBG), and artificial magnetic conductor (AMC). This structure has the capability to improve the performance of the resonant frequency, minimizing the size and improving the return loss of the design, while sometimes creating a filter notch to the design. SRR structure is a good candidate for energy harvesting because it can increase the conversion efficiency.
