6 Antenna

The antenna connection and board layout design are the most important part in the full product design and they strongly reflect on the product overall performances, hence read carefully and follow the requirements and the guidelines for a proper design.

6.1 GSM Antenna Requirements

As suggested on the Product Description the antenna and antenna line on PCB for a Telit GE863- PRO3 device shall fulfil the following requirements:

 

ANTENNA REQUIREMENTS

 

 

 

Frequency range

 

Depending by frequency band(s) provided by

 

 

the network operator, the customer shall use

 

 

the most suitable antenna for that/those

 

 

band(s)

Bandwidth

 

70 MHz in GSM850, 80 MHz in GSM900,

 

 

170 MHz in DCS & 140 MHz PCS band

Gain

 

Gain < 3dBi

Impedance

 

50 Ω

Input power

 

> 2 W peak power

VSWR absolute

 

<= 10:1

max

 

 

VSWR

 

<= 2:1

recommended

 

 

When using the Telit GE863-PRO3, since there's no antenna connector on the module, the antenna must be connected to the GE863-PRO3through the PCB with the antenna pad using a 50 Ω transmission line.

In the case that the antenna is not directly developed on the same PCB, hence directly connected at the antenna pad of the GE863-PRO3, then a PCB line is needed in order to connect with it or with its connector.
