AWR1843: AWR1843BOOST antenna radiation pattern, antenna geometry

Hi,

I have the following questions about the AWR1843BOOST antenna parametres:

1. Is there available any usable format (*.csv, *.txt etc.) of antenna radiation pattern datasets that is plotted in the user guide, section 2.7, Fig. 11, Fig. 12 (link below)?
2. In the user guide section 2.7, Fig. 10, the description of the figure with lambda ratios indicates the antenna spacing, but it is not clear which frequency corresponds to lambda (76 GhZ? 81GhZ?) and what is the spacing between Tx and Rx antennas.
   Is there available some more accurate geometry description of the antennas?

Thank you,
