Chapter 5 – Wireless Antennas
The Antenna
The antenna sub-system and integration in the application is a major issue: Choice of antenna (type, length,
performances, thermal resistance, etc.) These elements could affect wireless performances such as sensitivity and
emitted power.
GSM and CDMA Antenna
The integrated modem antenna connector is a SMA connector. The SMA connector incorporates a 'Screw-on' action
in order to make the connection easier while providing an excellent RF performance. An additional advantage is its
small physical size, which is 50% of the standard MCX connector.
This type of connector is suitable for the standard ranges of flexible and semi-rigid cables. The characteristic
impedance of the MMCX coaxial connector is 50 ohm. The antenna manufacturer must guarantee that the antenna
will be working according to the radio characteristics presented in the table below.
