5.6 IWR6843ISK Antenna
The IWR6843ISK includes onboard-etched long range antennas for the four receivers and three transmitters.
Figure 5-7 shows the PCB antennas.
Figure 5-7. PCB Antennas
Figure 5-8 through Figure 5-10 shows the antenna radiation pattern with regard to azimuth. Figure 5-11 through
Figure 5-13 show the antenna radiation pattern with regard to elevation for TX1, TX2, and TX3.
All of the measurements were done with a Tx and Rx combination together. Thus, for the -6dB beam width, you
must see a -12db (Tx (-6dB) + Rx(-6dB)) number.
