"The port has no terminals defined on it"

Dear all,
I've got an error while using HFSS. I want to divide my construction and add one more port. During this process I've got "Port 'p2': The port has no terminals defined on it".
Best regards,
Kate

I want to divide my construction and add one more port here File Upload - 128.

Dear all,
Firstly, I cannot divide it into three strips. May I use split command? Unfortunately, PIFA disappears after this...
Secondly, I have an error when I move port1 from antenna_feed to antenna_short or antenna_short2 after division...
Could anyone help?..
