Abstract
In this work, a 4 × 4 Rectangular Split Resonator (SRR) array with resonance at 5.8 GHz is proposed. By optimizing the geometry through genetic algorithm, sub-wavelength resonance at the desired frequency was obtained, while maintaining the antenna’s radiation efficiency at broadside. The total size of the antenna is 30 mm × 30 mm, thus ensuring compactness. The design was compared with a Circular SRR and an alternating sequence of Rectangular and Circular SRRs. Further, the permittivity and permeability of the structure was plotted, which was negative at the resonance frequency.
