Abstract
A novel lowpass filter with wide stopband and sharp skirt characteristics is proposed. To obtain the applicable lowpass filter, several cells of coupled T-shaped resonator, U-shape and dumbbell-shaped resonators are connected in series. The proposed filter has low insertion loss, high return loss in the passband and wide stopband. The transition band is from 3.18 to 3.29 GHz with −3 and −20 dB, respectively. Results of the fabricated filter exhibit a roll-off and relative stopband bandwidth of 217 and 137%, respectively. Measurement and simulation results show good agreement.
