Abstract

A complementary split-ring resonator (CSRR) based metamaterial is designed and investigated in this paper for microwave applications with effective medium ratio. This CSRR is the modification of the conventional split-ring resonator. Three square split-ring resonators (SSRR) are interconnected with a strip line as well as two splits in three square split-ring resonators are applied to increase the electrical length and coupling effect. The CSRR has an impact on the extraction of effective permittivity, permeability, and refractive index. The dimension of the designed unit cell is 5.5 × 5.5 mm2 that is printed on FR4 material. An 18 × 20 array structure is also investigated in this paper. The unit cell has a double negative region of 6.34–7.39 GHz and 8.20–9.98 GHz with effective negative refractive index region of 4.23–7.32 GHz and 7.40–10.0 GHz. The effective medium ratio is 8.0, which implies the effectiveness and compactness of the proposed CSSR design. The compact size, effective parameters, and effective medium ratio rate represent the suitability of the proposed metamaterial for practical C band microwave applications.
