Horst-type wilkinson power dividers for dual-band operation
There are three approaches for the use of composite right/left-handed transmission lines (CRLH TLs) in Horst Wilkinson power dividers (WPDs) because an original WPD presented by Horst includes two transmission line sections in its even- and odd-mode equivalent circuits. In this paper, two of them are presented in order to realize dual-band operation. The range of upper and lower band frequency ratios varies according to the application of CRLH TLs.
