3.4.1 Radar Detect Distance Measurement

The IWRL6432FSPEVM utilizes the same FR4 based antennas on the PCB as the XWRL6432BOOST. These antennas include three receivers and two transmitters.

Figure 3-14 TX and RX Antennas of the EVM
Note: The XWRL6432BOOST has an antenna gain of about 5–6 dBi across different antenna pairs.

The IWRL6432FSPEVM has same azimuth and elevation antenna radiation patterns as the XWRL6432BOOST.
