Hi TEAM,
I had got an antenna pattern question from customer. My customer copy IWR1642BOOST EVM antenna in HFSS software, all the size and the parameter are same with IWR1642BOOST EVM, but he can't get the same pattern as EVM did.
Could you please help to point out which parameter will cause this pattern? Is the RF source should began from BGA ball and transmit line?
Antenna pattern and the S11 figure are attached below.
Thanks.
Regards,
Wesley
