Abstract

In the letter, a compact dual-band Wilkinson power divider terminated with frequency-dependent complex impedance (FDCI) is proposed, for the first time. It is composed of two sections of coupled lines, two shunt transmission lines and a lumped resistor. By using the coupled lines, the FDCI at two bands can be matched. Further, the design equations for the proposed power divider are derived by using the even-odd mode decomposition technology. For verification, a prototype operating at 1.0 GHz and 1.8 GHz was designed, fabricated and measured with different terminal complex impedances at the two bands. The measured results show that the proposed WPD features equal power distribution, good impedance matching/isolation at two frequency bands.
