Abstract:
Metamaterial structure that provide electromagnetic properties not found in naturally occurring media; properties such as negative index of refraction, negative permeability or permittivity[1][2]. Complementary split-ring resonator (CSRR) used as a metamaterial structure. In this paper, we present a systematic numerical study, validated by accompanied experimental data, of individual complementary split-ring resonator (CSRR) with one, two and four gaps loaded in the conventional rectangular Microstrip patch antenna. We discuss the behavior of the magnetic resonance frequency, the magnetic field and current distribution in the CSSRs loaded microstrip patch antenna. We show that coupling of the CSRRs along the E direction results to shift of the magnetic resonance frequency to lower or higher values, depending on the capacitive or inductive nature of the coupling. There is an increase in the return loss, gain, bandwidth of the proposed Microstrip patch antenna. Simulation of microstrip patch antenna with CSSR structure using IE3D Electromagnetic simulator of Zeland software incorporation.
