CSRR Loaded CPW Bandpass Filter for WLAN Application.

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 metameterial effect in the normal substrate. 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 2.23 to 3.13 GHz with the return loss of -25dB and the 0 dB insertion loss. The size of the filter is about 16 x 16 mm2. With the above properties the proposed metamaterial filter can be used for the WLAN application.
