Zero-Biasing Split Ring Resonator using Metamaterial Element for High Gain Superstrates Ultra-Wideband Antenna

Complex materials with artificial structures known as metamaterials (MTM) have unique properties that draw several scientists to use them in a variety of research fields. In addition, MTM can go beyond some the restrictions placed on tools used technical practise while improving characteristics microwaves. The Internet Things (IoT) application calls for construction zero-index Split Ring Resonator (SRR) element superstrates an ultra-wideband antenna. Keep mind simulates behaviour is not found nature, namely zero-reflection phase (dB) resonance frequency. For this project, antenna SRR unit cell operating at 2.70 GHz built. has four inductance-related loops (r1, r2, r3, and r4), gaps (slots) are added ring produce capacitance effect. Parametric been done SSR interim identify best design zero indexes, permittivity permeability desired cells array design's 7 x 4 10 5 dimensions achieved dB 0° frequency range.
