摘要：
This paper presents construction of a composite right/left-handed (CRLH) transmission line (TL) using microstrip coupled lines. For getting high coupling in comparison to conventional edge coupled microstrip line, the floating slot in the ground plane is used. Two configuration named as SOS(short-open-short) the OSO(open-short-open) model are studied for realization of band pass filter. The floating ground equalizes the even and odd mode phase velocities and solves the difficulties arised in the fabrication process as it relaxes the required physical dimensions like coupled gaps between lines. Finally a bandpass filter having bandwidth of 56.7% and selectivity of 40 dB/GHz has been designed using OSO model and the experimental results are verified with EM simulated results.
