The finline based transmission line is used for realization of wide band pass filter. In this paper designing a bandpass filter for wide bandwidth, based on parallel coupled unilateral three finline structures. A design graph for symmetric three unilateral finline structures is presented for the design of bandpass filter. A bandpass filter of order 3 having center frequency of 10 GHz with fractional bandwidth of 20% is designed fabricated and measured. This wide bandpass filter is converted into symmetric and asymmetric dual band pass filters with the help of metamaterials (Split Ring Resonators SRR) on the other side of the finline structure is simulated with High Frequency Structure Simulator (HFSS) and fabricated. Transmission (S21) and reflection (S11) parameters of measured results compared with simulated results.
