Dear Dialog Team,
We are trying to leverage the antenna used in the DA14580_RD_WLCSP_SMTAG2_vC design for our Tags based on DA14585, but we have few queries:
1) Why is there a trace at the bottom layer of the antenna too and why are there vias connecting the top and bottom traces of the antenna? Don't PCB antennas have a trace on a single layer?
2) Can we remove the bottom trace of the antenna? Will it affect the antenna performance if we do so?
