6.4.1. PCB Design guidelines
When using the ME910G1, since there's no antenna connector on the module, the
antenna must be connected to the ME910G1 antenna pad (K1) by means of a
transmission line implemented on the PCB.
This transmission line shall fulfil the following requirements:
Coupling with other signals shall be avoided
Cold End (Ground Plane) of antenna shall be equipotential to
the ME910G1 ground pins
The transmission line should be designed according to the following guidelines:
• Make sure that the transmission line’s characteristic impedance is 50ohm ;
• Keep line on the PCB as short as possible, since the antenna line loss shall be less than about 0,3 dB;
• Line geometry should have uniform characteristics, constant cross section, avoid meanders and abrupt
curves;
• Any kind of suitable geometry / structure (Microstrip, Stripline, Coplanar, Grounded Coplanar
Waveguide...) can be used for implementing the printed transmission line afferent the antenna;
