Hi Antonio,

The suspended substrate is a kind of structure of sandwich. It looks like a microstrip suspended between two metal conductor planes. The distance from suspended substrate to each conductor plane may be identical or not.

You may try to find a microwave book published ten years ago or earlier. It is seldom discussed in a modern RF book.

I hope it is helpful.

By the way, I find a picture of the suspended substrate in ADS and upload to my website. The picture link is shown as following. You may think about to simulate your design in ADS if it meets your requirement.

Good luck.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB.
