GSM/UMTS antenna selection for a small device

(1/1)

Mad ID:
Hi,
I'm using a Quectel UC20-E 3G modem.

The operating bands should be 850/900/1800/1900/2100MHz. The PCB size is small, i.e. 31x63mm. I guess that PCB is too small for a ground-dependent PCB antenna like PIFA.

I have found this antenna from Molex

The drawback is price (3$ @ 1000pcs) and it is very big (107mm long).

Can someone point me in the right direction, what antenna type would fit this design? Any recommendation for a particular antenna?

Thanks.
