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 metameterial
effect in the normal substrate. It achieved 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 2.23 to 3.13 GHz
with the return loss of -25dB and the -0.2 dB insertion loss. The size of the filter is about 16
x 16 mm
. With the above properties the proposed metamaterial filter can be used for the
WLAN application.
