The author thanks Dr. R. Sinha very much for providing detailed design equations for the proposed dual-band impedance transformer in <xref ref-type="bibr" rid="ref1">1 . Note that the analytical solutions for Z 1 are very necessary, which are developed in <xref ref-type="bibr" rid="ref1">1 , in closed form. In fact, the generalized and closed-form solutions for this kind of impedance transformers have been published in <xref ref-type="bibr" rid="ref2">2 . It is very interesting that all results in <xref ref-type="bibr" rid="ref2">2 can be degenerated to the simple solutions in both <xref ref-type="bibr" rid="ref1">1 and the presented results in the comments by Dr. R. Sinha, when X In = 0 is considered in <xref ref-type="bibr" rid="ref2">2 .
