A stripline consists of a central conductor surrounded by dielectric material between two groundplanes. Striplines, in many cases, can be used where microstrips would be, so long as size is not a constraint. In fact, striplines often make components such as band-pass filter's more accurately, with more symmetric roll-off and no lower cutoff frequency.

**Note: Like our stripline impedance calculator, all of our RF calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
