B.4.2 Example application 2
Figure 38 shows a miniaturized application design used for evaluation of TRP and range. This tiny
design with a 7.5 x 12 mm PCB size gives with ANNA-B1 a TRP of -8.4 dBm and ~100 m range. The
antenna radiation characteristic of ANNA-B4 and ANNA-B1 is the same however the higher power of
ANNA-B4 shall be considered when comparing absolute levels of TRP and range. The 4 dB higher
output level of ANNA-B4 will in theory give roughly a bit more than ~150 m range.

Table 26 shows the antenna radiation patterns for the tiny ANNA-B1 module.
Theta = 60, Phi = 45 Theta = 1.4, Phi = 189.5
