Flexible substrate(s)

Hi, does anybody have any experience with flexible substrate materials? For example to make an antenna on a curved surface...

Which are some of the available technologies for processing such substrates, does anybody know? Or at least a list of substrates!

THANKS!

RT-Duroid 5870

a good thesis

Ok, thanks, that's interesting...however I am looking for substrates that can be placed over irregular surfaces, and can conform to them....I don't think any of the soft(er) substrates even like Duroid for example can do this properly, so what other alternatives are there?

Also the substrate should be available in a thick form, such as 25 - 60 mil if possible...

ANy other ideas or suggestions?

THANKS!

Hi Dan

you can use the 10-30 layers of flex3600
and you will get flex ant.

I saw them at a show last weekend. They are able to deposit silver onto very thin layers of lexan. The stuff is very flexible. You can not form a sharp crease, but you can sure bend it pretty tightly.
