Defining an Infinite Planar Multilayer Substrate
Define an infinite planar multilayer substrate.
Some applications for infinite planar multilayer substrates are as follows:
- Add a PEC ground plane at the top and bottom layers to model a stripline.
- Add a PEC ground plane at the bottom layer to model a microstrip.
- Use the substrate (without a PEC ground plane) to model real earth.
- Use a finite thickness substrate without any ground plane to model a printed antenna (for example, a log-periodic antenna).
