3.7 IWR6843ISK-ODS Antenna
The IWR6843ISK-ODS includes on-board-etched short range antennas (approximately 12-15 meters for
people detection) for the four receivers and three transmitters. Figure 49 shows the PCB antennas
arrangement. This provides equal angular resolution both in Azimuth and Elevation directions with the help
of 4 × 3 virtual antennas positions.
