I am trying to learn momentum. There is a momentum example "LPF_4_8_ GHz" that comes with the genesys download. I can load this example, and make changes to it, and run it an see the response. The notes call this a "microstrip filter", but it does not look like one. As far as I can tell, this is a suspended stripline filter, with a 10 mil thick substrate and air above and below it (air layers 232.28 mils thick each). Am I reading this correctly???? Or does it ignore the "air below" layer???
Thanks
