Dual band unequal power divider

摘要

PURPOSE: A dual band asymmetry power divider is provided to enable the use of different two frequency bands using a dual-band composite right/left-handed(CRLH) transmission line. CONSTITUTION: The dual band asymmetry power divider comprises a CRLH transmission line(410) of meta material and a branch line coupler(420). The CRLH transmission line of the meta material comprises a series capacitor, a series inductance , a parallel inductance, and a parallel capacitor. The branch line coupler comprises two input transmission lines connected to the output terminal of a CRLH transmission line of meta material. The branch line coupler enables asymmetry power distribution by diversifying the length of one between two input connection transmission lines.
