(ProQuest: ... denotes formulae omitted.) 1.Introduction Suppression of unwanted range frequencies and avoidance of noise are an important issue in the microwave and wireless communication systems. Figures 2(a) and 2(b) show respectively the frequency response of the rectangular SRR and extracted real and imaginary of the permeability. 3.Analysis and design of the proposed band-stop filter A compact and miniaturized microstrip band-stop filter was built by using Rectangular SRR unit cell. Due to its relatively low cost, the proposed circuit is printed on Flame Resistant 4 epoxy substrate which is characterized by a relative permittivity of 4.4, a loss tangent of 0.025 and a thickness h= 1.6 mm. The geometrical configuration parameters of the proposed BSF based on rectangular Split Ring Resonator is shown in Figure 3. First of all, the proposed structure without metamaterial resonator has been simulated so as to understand the influence of the chosen rectangular SRR unit cell.
