The objective of the presented article is to design a compact metamaterial-based dual-band antenna that meets the frequency requirement of 5G. The antenna consists of a Circular Split Ring Resonator structure with a defective ground plane and slots to enhance the bandwidth and gain parameters. Metamaterial-based Microstrip patch antenna produces unique electromagnetic properties that allow us to control over the antenna parameters with a compact size. FR-4 epoxy is used as a substrate its dielectric constant is 4.4 and its loss tangent is 0.02. Dimensions of the antenna are 20 x 12 x 1.6mm3 with a very compact size and cost-effective. The proposed metamaterial-based antenna resonates at dual bands at 3.24GHz and 5.46 GHz respectively. The peak gains at resonant frequencies 3.45GHz and 5.46 GHz are 0.9 dB and 2dB respectively. The proposed antenna shows S-parameters at S11, which is -12.13dB at frequency of 3.45 GHz and -15.165 at a frequency of 5.46 GHz. The proposed antenna can effectively work for WLAN and WiMAX applications. The antenna covers the frequency spectrum from 2 GHz to 8 GHz with a centre frequency of 5 GHz. The proposed antenna is cost-effective
