There's a coplanar waveguide calculator on our calculator page! The microstrip calculator determines the width and length of a microstrip line for a given characteristic impedance (Zo) and electrical length or vice versa.

( Contact us if you would like to see other calculators) 2. The substrate parameters (ε r and h) and the frequency of interest are required.

Coplanar Waveguide with Ground Calculator. Go to the calculator section. This calculator is designed to calculate the characteristic impedance of a microstrip - a flat conductor suspended over a ground plane with a dielectric between them (see diagram below). (1) When the character impedance (Zo) of the conductor space (w) is computed. Input w, and click on [ Analyze ] button. Return to the top. Coplanar Capacitance Model Capacitance between two coplanar flat conductors is: Units: Farads. Description The capacitance calculated using this tool is the capacitance between two coplanar flat conductors. No matter how many structures we include in the Si8000m and Si9000e it seems that there are never enough. Coplanar Waveguide Calculator. While commonly constructed using printed circuit boards, this structure can also be built using other materials as long as there is a conductor separated from a ground plane by some dielectric material. Coplanar Waveguide Analysis/Synthesis. Conditions (weak microstrip mode, low side capacitance): S>>T, H>T, 0.125 × W ≤ S ≤ 4.5 × W, W + 2 × S ≤ 5 × H, dielectric constant >3 for higher accuracy. Coplanar Waveguide Analysis/Synthesis Calculator. Input w, and click on [ Analyze ] button. The electrical parameters may be determined from specified physical parameters, or the physical parameters required to meet a given set of electrical parameters may be found.

Input the parameter of the circuit board and center frequency. Features. Assumptions and Limitations Dimensions are … Synthesize Asymmetric coplanar and differential coplanar controlled impedance structures Model More Structures: Two tricks that enable you to model structures that aren’t included in the Si8000m and Si9000e . er : s [mm] h [mm] t [um] fo [MHz] w [mm] >>> Zo [ohm] Zo [ohm] >>> w [mm] er eff: k : lambda/4 [mm] [ How to use ] 1. A cross-section of a microstrip transmission line is shown below. (1) When the character impedance (Zo) of the conductor space (w) is computed. This calculator provides accurate microstrip transmission line analysis and synthesis. Input the parameter of the circuit board and center frequency.

More importantly, it can provide extremely high frequency response (100 GHz or more) since connecting to CPW does not entail any parasitic discontinuities in the ground plane. er [FR4=4.6(1MHz=4.7 1GHz=4.3)] s [mm] h [mm] fo [MHz] w [mm] >>> Zo [ohm] Zo [ohm] >>> w [mm] er eff : k : lambda/4 [mm] [ How to use ] 1. ... like on microstrip.
