Design Note DN033
All results presented in this document are based on measurements performed with the CC1101-Q1 EM attached to the SmartRF04EB. The CC1101-Q1 EM has been adjusted in the method shown in Section 3.2 at variant frequency in the state of being attached to the SmartRF04 EB,
The bandwidth was evaluated from VSWR property. The radiation pattern measured in an anechoic chamber will be described. Figure 13 shows how to relate radiation pattern to the orientation of the antenna. The antenna gain was obtained by averaging the power gain in vertical and horizontal polarization measured in the YZ, ZX and XY planes.
