SIW Cal

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

Please note that this calculator is intended solely for educational purposes and is not meant for commercial use.

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 a 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.
