3.3 Antenna
BGM220S modules include an integral antenna on board with the characteristics detailed in the tables below.
Table 3.1. Antenna Efficiency and Peak Gain (BGM220S12A)
Parameter
With optimal layout Note
Efficiency
-1.4 to -2.6 dB
Antenna efficiency, gain and radiation pattern are highly depend-
ent on the application PCB layout and mechanical design. Refer
to
for recommendations to achieve optimal
antenna performance.
Peak gain
