Suspended Substrate - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

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. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
