3.4. Antennas

The 4G module comes with 2 cellular antennas for improving the signal reception: normal (main) antenna and

diversity antenna. Besides, a 3

antenna is also included for the GPS receiver (when it is available in the 4G

module).

All these 3 antennas are the same model and can be used in any of the 4G sockets. The operating bands of

the dipole antenna go from 698 to 960 MHz and from 1710 to 2690 MHz. The maximum gain of the antenna is

observed at 2.6 GHz: 3.4 dBi.

To get the maximum performance, it is recommended to place the antennas like that:

•

The main cellular antenna should be in vertical position, pointing to the sky, in order to radiate better to the

cellular base stations around.

•

The diversity cellular antenna should be in horizontal position (orthogonal, 90º, to the main antenna). Besides,

the plane where the antenna is should be also orthogonal to the main antenna’s plain. Finally, it is advised to

place this 2nd cellular antenna as fas as possible from the main antenna. These 3 measures will maximize the

gain due to reception diversity.

•

The GPS antenna should be in horizontal position, because the GPS satellite signal will come from above.
