Abstract
A bandpass filter (BPF) of 2.24 GHz centre frequency and 44.6% fractional bandwidth, with a wide attenuation band is proposed in this article. The paper is focused on the analysis of complementary split ring resonator (CSRR) as a unit section of metamaterial and its application in designing of a bandpass filter. The proposed BPF structure consists of a stepped impedance stub-loaded resonator incorporated with the CSRR to suppress the harmonics to improve the attenuation band characteristics. A brief parametric study of the CSRR cell is done to demonstrate its role while suppressing the unwanted harmonics. The structure is fabricated, and measured to show a consistency with the IE3D simulated results.
