Antenna 2
All GND pads should be connected to a top layer copper
pour with no thermal reliefs.
GND clearance around antenna ports (pin 30, 32) should
be a minimum of 15mils to reduce capacitance. If the
U.FL connector is used for the antenna connection, pads
30 and 32 should be omitted.

Ensure that the antenna line impedance is 50Ω
Keep the antenna line on the PCB as short as possible
Antenna line must have uniform characteristics, constant cross
section, avoid meanders and abrupt curves. Matching elements (L
or C) can be added, but are not necessary for a well designed
layout.
Keep, if possible, one layer of the PCB used only for the ground
plane
Place EM noisy devices as far as possible from the M6e-Micro
Keep the antenna line far away from the power supply lines,
noisy devices such as fast switching ICs. If a switching power
supply is used, ensure that the switching frequency is 500kHz or
higher.
