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