Substrate Integrated Waveguide

Application ID: 12127

A waveguide-type structure can be fabricated on a substrate by adding vias between the microstrip line and the ground plane. Such a device will behave as a high-pass filter and is attractive because it is easy to fabricate. A model is set up that shows the S-parameters as a function of frequency. A sharp cutoff is shown at the expected frequency.

This model example illustrates applications of this type that would nominally be built using the following products:
