A.4 JN5168-001-M00 Antenna Radiation Pattern
Figure 7, 8 & 9 are simulated 3D radiation plots of the JN5168-001-M00. They are provided here to help the user
orientate the module in end equipment in an optimal way. These visualisations are an accurate representation of the
antenna radiation pattern in the 3D space.
The 2D XZ plots for each channel are shown in Figure 10. These are actual measurements in an anechoic chamber
with the JN5168-001-M00 mounted on a DR1174 carrier board from the JN516x-EK001 Evaluation kit. The device
under test and the antenna height was 1m and the values are in dBuV/m at a distance of 3m.
Figure 11 is a plot of the peak field strengths for a JN5168-001-M00, JN5148-001-M00 and JN5168-001-M03. The
M03 is used with a λ/2 vertical antenna. Figure 11 shows that the new integrated antenna is 1.5-3dB better than the
JN5148-001-M00 and is within 1.5 dB of a JN5168-001-M03 λ/2 vertical.
