Novel Wilkinson-Type Power Dividers Based on Metamaterial Transmission Lines

This paper focuses on applications of the metamaterial left-handed transmission lines to the design of novel Wilkinson-type power dividers. Novel configurations of broadband 180deg Wilkinson power dividers suitable for practical implementation are proposed. A concept of designing dual-band Wilkinson power dividers based on a combination of right-handed and left-handed transmission line sections is considered as well. A band broadening technique for the dual-band Wilkinson power dividers is discussed.
