Figure 5-1 Main Antenna Design

Figure R1, C1, C2 and R2 composition of the antenna matching network for antenna debugging, the

default R1, R2 paste 0 ohm resistor C2, C1 empty paste, to be antenna factory after the antenna to

determine the value of the antenna.

Connector RF in the figure is used for testing and conducting test (for example, CE, FCC, etc.), which

need to be placed as far as possible by the module, the RF path from the module to the antenna feed

point should be kept 50 ohm impedance control.

Figure 5-2 Div Antenna Design

default R3, R5 paste 0 ohm resistor C5, C3 empty paste, to be antenna factory after the antenna to

determine the value of the antenna.
