PDOA - Antenna separation

Looking to implement PDOA using two DW1000 radio ic’s sharing the same clock.

I am looking at using the following ceramic antenna: 3100AT51A7200E https://www.johansontechnology.com/datasheets/3100AT51A7200/3100AT51A7200.pdf

According to the AOA technical note the antenna should be placed lamba/4 separation.

With the above antenna, should the separation be from the edges or centre of the antenna?

Hi John,

There is a Beta PDoA kit available from Decawave that has custom antennas designs for this application.
