Substrate Integrated Waveguide
Model 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.
|INTEGRATED WAVEGUIDE: Vias are added between the microstrip line and the ground plane of an integrated waveguide where the results show a sharp cutoff at 8.664 GHz.|
