SIW Cal

SIW Calculator and SIW Designer

This app is developed by WoliModel Inc.

SIW Cal is a calculator tailored for RF Engineers and/or students.

By inputting substrate information and desired impedance values, SIW Cal can determine the microstrip line width and effective dielectric constant of the microstrip line.

Additionally, this tool aids in the design of a Substrate Integrated Waveguide (SIW) and facilitates the creation of a seamless transition between a microstrip line and the SIW.

Utilizing the outcomes provided by this tool, you can construct an RF transmission line with decent performance. These results serve as a good starting point for further refinement in 3D EM simulation software, allowing you to fine-tune your design for optimal results.
