Abstract :
A coupled line narrowband filter with second harmonic suppression is presented. A Novel narrow bandpass filter with sharp rejection at the lower frequency is proposed using open loop resonator. The stopband characteristics of complementary square split ring resonator (CSRR) are studied and designed to suppress the second harmonic frequency. CSRR loaded with the proposed filter for harmonic suppression is demonstrated. The CSRR is optimized to create the required bandstop characteristics without affecting the desired bandpass frequency. The proposed CSRR configuration provides a harmonic suppression at 2.8 GHz and open loop resonator resonates at 1.5 GHz to bandpass the desired frequency. Results are compared with the full wave simulation analysis and presented.
