摘要： The present invention relates to a power divider and a power combiner employing dual band-Composite Right/Left-Handed (CRLH) transmission lines. A power divider including an input terminal and two output terminals according to the present invention includes two transmission lines each having two terminals connected to the input terminal and the output terminals, respectively, and two short-stubs having one terminals connected to the output terminals, respectively, and the other terminals connected to grounds. The transmission line may employ a first dual band-CRLH transmission line having a double value of a termination impedance, which is substantially connected to the output terminal, as a characteristic impedance, and the short-stub may employ a second dual band-CRLH transmission line, which has substantially the same value as that of the termination impedance as a characteristic impedance. The first dual band-CRLH transmission line and the second dual band-CRLH transmission line generate phase delay of 90 degrees in a high frequency band and phase delay of −90 degrees in a low frequency band with respect to an input signal.
