Microstrip Inductance Calculator
Microstrip Inductance Calculator calculates the inductance of a microstrip transmission line based on its physical dimensions. Enter the trace width, trace length & substrate height, and the calculator will display the resultant Microstrip Inductance in microhenries (µH).
Enter the values of trace width, trace length and substrate height and click on calculate to get Microstrip Trace Resistance value.
What is Microstrip Inductance?
The microstrip inductance is the inductance of a microstrip transmission line. In a high-frequency design, like antennas and filters, it is quite important to set some characteristics of the signal, like impedance or speed of propagation, using inductance. Microstrip lines are used because they are easy and lightweight, suitable for high-frequency microwave signals.
How is it calculated?
This calculator uses trace width W, trace length L, and substrate height H to calculate the inductance of the microstrip in microhenries μH.
Formula:
The calculation uses models like those in the document IPC-2141A, which gives a good approximation to the inductance of the microstrip.
Where:
- L = Length of the microstrip
- W = Width of the trace
- H = Height of the substrate
Practical Application:
This calculator finds wide usage in microwave circuit design, where, instead of using the normal inductors, microstrips are used. Such circuits include antennas, impedance-matching networks, and filters that require an exact value of inductance to get desired electrical performance at high frequencies.
The microstrip inductance calculation enables the engineer to design the desired inductive properties into a circuit without bulky discrete inductors, especially at very high frequencies where traditional inductors become almost impractical.
