Figure 3-16 RF signal layout design about MAIN_ANT for reference (the same for

AUX_ANT)

For the PCB designed by the user, the impedance of all the RF signal tracks must be

50 Ω. Generally, the impedance depends on the medium factor, track width, and

distance from the floor.

In order to reflect the rules of design, the following figures indicate the complete

structure of the microstrip and stripline with an impedance of 50 Ω as well as the

reference design for stack.
