Additionally, these recommendations regarding the antenna system must be followed:
 Do not include an antenna within a closed metal case.
 Do not place the antenna in close vicinity to end users, since the emitted radiation in human tissue
is limited by regulatory requirements.
 Place the antenna far from sensitive analog systems or employ countermeasures to reduce
electromagnetic compatibility issues.
 Take care of interaction between co-located RF systems since the GSM transmitted RF power
may interact or disturb the performance of companion systems.
 The antenna shall provide optimal efficiency figure over all the operating frequencies.
 The antenna shall provide an appropriate gain figure (i.e. combined antenna directivity and
efficiency figure) so that the electromagnetic field radiation intensity does not exceed the
regulatory limits specified in some countries.
 Consider including extra footprints for a “pi” network in between the cellular module and the
antenna, for further improvement in the antenna matching circuit to reach optimal antenna
performance.
