dear sameer,

please refer my work with Darshit Trivedi

Best wishes

Respected Dr. Dwidevi

I have no issue related to design. I have already designed my antenna on cotton substrate. My issue is different, I wish to fabricate my antenna by depositing copper on selected areas and etching the rest. But, when etching is done cotton substrate also gets affected. Kindly suggest me on that.

Regards

Sameer

In a process of deposition, block the area which is not to deposited by suitable removable covering (could be easily removable plastic or timber thin layer) so that process of etching itself not required

You can use a kind of ink-jet-printer like machine to print silver paste on your cotton substrate to realize specific metallic patterns.

Respected Prof. Meng

Are you talking about deposition through silver nano particles?

Regards

Sameer

Hi Sharma, look this website

good luck!

Dear Sameer Kumar Sharma,

How did you model the cotton on your simulations?

Do you know how to model cotton in CST?

Thanks and regards,

Hi Isidoro,

Cotton is available in several permittivities. I would suggest you buy a particular type of material—> characterize it and then use that permittivity for your substrate.
