A novel composite right/left-handed transmission line (CRLH-TL) meta-material with two left-handed bands based on the structure of microstrip line is proposed.The topology and method of operation of the line are discussed.The two pass bands of the CRLH-TL exist at 2.5 GHz and 6 GHz respectively.S11 and S21 can be achieved through simulation which validates the existence of Left-handed chrematistics.A CRLH-TL with two main pass bands would play an important part in a number of quad-band applications.

Key words: composite right/left-handed;dual left bands;defected ground structures
