•
Place the noisy EM devices as far as possible away from the ME310G1 antenna
line.
•
Keep the antenna line far away from the ME310G1 power supply lines.
•
If there are noisy EM devices (such as fast switching ICs, LCD, and so on) on
the PCB hosting the ME310G1, shield the antenna line by burying it in an inner
layer of the PCB and surrounding it with the Ground planes, or shield it with a
metal frame cover.
•
If noisy EM devices are not present around the line, it is preferable to use
geometries such as Microstrip or Grounded Coplanar Waveguide as they
typically ensure less attenuation than a Stripline of the same length.
The following image is showing the suggested layout for the Antenna pad connection:

PCB Guidelines in Case of FCC Certification
In case FCC certification is required for an application using ME310G1, according to FCC
KDB 996369 for modular approval requirements, the transmission line must be similar
to the one implemented on the ME310G1 interface board and described in the following
chapter.
