Dear Estephania,

Thanks for your comment.

Now I can open the files.

Hello,

When downloading the latest version of the application note you will find a pdf file, most of the information you are requesting regarding the antenna data is available from Chapter 5-6.

Also , the issue might be realted to the version of the viewer you are using , there are some versions that only support from certain versions up. I would recommend you to change the viewer for another on, I dowloaded the files and was able to open it without issues. Coudl you please try with another viewer?

Dear Estephania,

Thanks for your prompt reply.

But, when I tried to open it with other version of Allegro viewer,

The same error message has occurred.

The Allegro version I've checked is 16.6, 17.2 and 17.4

Could you let me know what the allegro version of the Antenna design on Application Note is?

Thanks,

Andy
