Hi All,

Can anyone direct me to information about ferroelectric materials
for microwave/antenna applications ?

Anything will help - Basics, Analysis, applications etc.

Tnx alot,
P.
 

for a start you can search for BSt(barium strontium titanate) phase shifters in google.

i think it is corect to say as ferromagnetic/ferrites rather than as ferro electric materials since we refering microwave .
 

Ok, Thanks.

What about some ferroelectric materials applications in the microwave/antenna field ?
Has anyone tried anything like that here?

P.
 

Ferroelectrics (BST-based) are claimed for tunable components in microwave: tunable filters, tunable phase shifters, tunable antennas, etc.

Here some related links:

If you have more detailed questions, feel free to ask.
Several IEEE articles exists about this topic.

Added after 4 minutes:

Here a document!

Hi Fi All!

Where I can by Ferroelectric materials (many properties and many profiles,
plates rings, remanent polarisation etc...)?
