Simple closed‐form expressions for the analysis of broadside coupled suspended substrate stripline is presented. The expressions are valid over a wide range of structural parameters and dielectric constants. The validity range of this expression for structural parameters is 1.0 ≤ ε r ≤ 30.0 (dielectric constant), 0.2 ≤ W/b ≤ 10.0 (strip width), and d/b ≤ 0.5 (substrate thickness). The average accuracies of the present expressions are <0.8% and <0.6% for even‐ and odd‐mode impedances, respectively. The maximum deviation is ±1.25% and ±1.16% for even‐ and odd‐mode impedances with respect to the reference values. This closed‐form model is useful for the interactive CAD analysis of microwave and millimeter‐wave circuit. © 2004 Wiley Periodicals, Inc.
