Antenna choice for 2G/NB-IoT
Hello,

I'm looking for an antenna adapted to 2G & NB-IoT communications for European market and I'm wondering if a configuration would exist with SR4C033 to fit to bands 8 and 20. The datasheet shows separate configurations for 5 & 8 and 20.

If not possible, which antenna would you advise to use for this application ?
PCB total size is 115x48mm (h x w) but the surface for the antenna is of course limited!

Thank you,
Yoann

For your application and PCB size i would suggest one of the following assuming you wish to use an SMD solution.

Similis (SR4C005)

Calvus (A10340H)

Integra (SR4L049)

Hello,

We already use SR4L049 for a 2G/3G design, it is the only choice that fits to the mechanical constraints.
Is there a way, using the matching circuit, to optimize the performances for 791-960 MHz frequencies, neglecting higher frequencies ?

Thank you,
Yoann
