Abstract

We greatly appreciate the comments on [1] by Sinha [2] . There are typos for [1, (1)-(3)] . The equations should be corrected as \begin{align*} A=&D=-\frac {Z_{o} -(Z_{e} +Z_{o} )\cos ^{2}\theta }{Z_{o} +(Z_{e} -Z_{o} )\cos ^{2}\theta } B=&\frac {jZ_{e} Z_{o} \sin 2\theta }{Z_{o} +(Z_{e} -Z_{o} )\cos ^{2}\theta } C=&\frac {j\sin 2\theta }{Z_{o} +(Z_{e} -Z_{o} )\cos ^{2}\theta }. \end{align*} Consequently, two connected Schiffman phase shifters are employed to provide a phase shift of 180° at $f_{0}$ . When operated within the first passband $f_{1}$ , the electrical length $\theta $ of each Schiffman phase shifter will be less than 90°. Therefore, with $\vert S_{11}\vert = 0$ and $\vert S_{21}\vert = 1$ , $Z_{e}$ and $Z_{o}$
