The microstrip calculator determines the width and length of a microstrip line for a given characteristic impedance (Zo) and electrical length or vice versa. The substrate parameters (εr and h) and the frequency of interest are required.


Enter values for Zo and Electrical Length to determine the physical width and length of the microstrip line. Press Synthesize to see the results.


Enter values for W and L for a microstrip line to determine its Zo and Electrical Length. Press Analyze to see the results.
