With the trend of integrating several applications in communication devices becoming increasingly common, the need to design multi-band microwave components has become more important than ever. Metamaterial lines or left-handed transmission lines (LHTLs), on account of their unique dispersion properties, are suitable for multi-band applications [1, 2]. This Letter presents a quad-band power divider which is implemented by replacing the transmission line (TL) segments of a previously proposed dual-band power divider (shown in Fig. 1a) [3] with left-handed (LH) cells. In this articel, A quad-band equal power divider has been designed by exploiting the multi-band operation of left-handed transmission lines. Unit cell design based on dispersion analysis is provided. A practical power divider that demonstrates equal power division at frequencies 0.47, 0.8, 1.85 and 3.35 GHz was designed and fabricated by implementing the lefthanded cells in microstrip technology
