Antenna requirements
This module is not available with printed antenna. An external one has to be
added to achieve correct communication between the products. Several
possibilities:
The best technical/economical compromise is a ¼ wave (8.6 cm length)
antenna soldered on the “mother board”. The link between the RFin_out pin
of the module and the antenna should be a 50Ω line. The larger the ground
plane around the antenna, the more efficient and "isotropic" it will be.
If necessary, this antenna can be distant thanks to a coaxial cable connected
to the “mother board”; the line must be a 50Ω line.
