• The ground surrounding the antenna line on PCB has to be strictly connected to the
main Ground Plane by means of via holes (once per 2mm at least), placed close to
the ground edges facing line track;
• Place EM noisy devices as far as possible from ME310G1 antenna line;
• Keep the antenna line far away from the ME310G1 power supply lines;
• If EM noisy devices (such as fast switching ICs, LCD and so on) are present on the
PCB hosting the ME310G1, take care of the shielding of the antenna line by burying
it in an inner layer of PCB and surround it with Ground planes, or shield it with a
metal frame cover.
• If EM noisy devices are not present around the line, the use of geometries like
Microstrip or Grounded Coplanar Waveguide has to be preferred, since they
typically ensure less attenuation if compared to a Stripline having same length;
