The novel technique of developing Chebyshev Dumbbell DGS low pass filters (LPFs) is presented in this paper. The ground plane of a standard 50-ohm transmission line is perturbed by Dumbbell called defected ground structure (DGS) to generate ultra-rejection band at X-Band that is beneficial to higher order harmonic suppression. A comparison of Meander shaped, circular complementary split ring resonator (CSRR) and Dumbbell DGS has been evaluated. An improved Chebyshev Dumbbell DGS LPF with compensated microstrip line has better rejection bandwidth at the X-band frequency. © 2015 IEEE.
