6. Antenna Performance
This section details antenna radiation patterns for the DWM3001CDKE1.0 Design Kit board. Figure 2 presents a view of the
measurement planes considered in this document.
Table 12 and Table 13 show antenna radiation patterns for the DWM3001C module mounted on the DWM3001CDKE1.0 carrier board
at Channels 5 and 9 respectively. Three planes in the spherical space about the center of the board are measured, with V and H plots
representing perpendicular vertical and horizontal components.
The DWM3001C antenna is vertically polarized, meaning that the module is intended to be positioned vertically upright when used in an
RTLS system. An omnidirectional radiation pattern is seen in the XZ plane when observed by another antenna which is also vertically
polarized. This is shown in the XZ plane antenna patterns, where the vertically polarized plot (V) has a circular, or omnidirectional
shape.
If the antennas are oriented perpendicular relative to each other, then the polarization changes. In this case, the horizontally polarized
pattern (H) applies and there are nulls at certain angles which can limit range and introduce location inaccuracy. Table 11 presents the
key characteristics of the DWM3001C’s antenna.
