Abstract : Metamaterial is an artificial material which is used to produce negative effects in the materials. In this paper a bandpass filter is proposed by introducing the metamaterial effect in the normal substrate. It was named as novel because of achieving negative effects from the normal substrate material with a compact circuit size of the structure. A coplanar waveguide transmission line is loaded with complementary split ring resonators for providing the structure with negative effects. The proposed filter is simulated and characterized using Method of Moments based IE3D simulator. The designed filter has a bandwidth of 3.2 to 5.2 GHz with the return loss of -45dB and of -0.2dB insertion loss. The size of the filter is about 12 × 12 mm2. With the above properties the proposed metamaterial filter can be used for the Wi-Max application.
