The purpose of this paper is to propose a new circular-shaped metamaterial (CM) design for X- and Ku-band applications. The discovery of exotic characteristics in metamaterial encourages to carry out this research study. The proposed design is numerically simulated by utilising Computer Simulation Technology (CST) software. The CM structure consists of few circular rings that designed on 8 × 8 mm2 and 1.6 mm thick of FR-4 dielectric substrate material. The Finite Integration Technique (FIT) used to perform the simulation in CST. Frequency range of 4 to 18 GHz is adopted and the CM design manifest resonance frequencies at 8.19 GHz, 11.32 GHz (X-band) and 16.39 GHz (Ku-band). These resonance frequencies possess an acceptable magnitude values for instance, -30.70 dB, -22.59 dB, and -20.13 dB respectively. In additional, the proposed CM design exhibits left-handed characteristic at both resonance frequencies. Therefore, CM with unique behaviour can be applied for many current application fields such as satellite communication, wireless computer networks, weather monitoring, and etc.
