Metamaterial surfaces play a vital role to achieve the surface waves suppression and in-phase reflection,in order to improve the antenna *** this paper,the performance comparison of a fifth generation(5G)antenna design is analyzed and compared with a metamaterial-based antenna for 5G communication system *** surface is utilized as a reflector due to its in-phase reflection characteristic and high-impedance nature to improve the gain of an *** conventional conducting ground plane does not give enough surface waves suppression which affects the antenna performance in terms of efficiency and gain *** factors are well considered in this work and improved by using the metamaterial *** radiating element of the proposed metamaterial based antenna is made up of copper material which is backed by the substrate,i.e.,Rogers-4003 with a standard thickness,loss tangent and a relative permittivity of 1.524 mm,0.0027 and 3.55,*** proposed antenna with and without metamaterial surface operates at the central frequency of 3.32 GHz and 3.60 GHz,*** traditional antenna yields a boresight gain of 2.76 dB which is further improved to 6.26 dB,using the metamaterial *** radiation efficiency of the proposed metamaterial-based 5G antenna is above 85%at the desired central frequency.
