In this paper, the design and the analysis of the double square ring (DSR) metamaterial is presented, which is based on the equivalent circuit theory and the analysis of the distribution of the electromagnetic field. Based on the retrieval algorithm, the effect of the structural parameters on the effective permittivity and the effective permeability are proposed. The effective permittivity and the effective permeability of the designed DSR metamaterial are simultaneously negative in the range from 4.8GHz to 5.65GHz. A conventional microstrip antenna is designed as comparison, and the analysis of the microstrip antenna is not written in this paper for brevity. The superstrate is composed of an 44 array of the DSR metamaterial, and the novel antenna is consist of the conventional microstrip antenna and the superstrate. The effect of the distance between the superstrate and the antenna are simulated by HFSS software, and the novel antenna is proposed according to the analysis of the distance. The simulation results show that the gain of the novel antenna increased by 1.1dB, and the half power beam width decreased by 40.9°. Therefore, it is concluded that the performance of microstrip antenna can be improved by using DSR metamaterials.
