A new scheme with an interdigital line and a defected ground structure for dual-band operation is dealt with in this letter. The proposed structure is analyzed using a series L-C resonator model added a parasitic shunt capacitance. The nonlinear phase of this structure is dependent on the dumbbell size of the defected ground. This proposed scheme is applicable for a short-ended stub circuit and a dual pass-band filter at the centre frequencies of 860 and 1810 MHz.
