Can someone suggest best antenna for quectel ec200t in elevator cabin?

I have a question Does someone know which GSM/GPRS antennas are best for quectel ec200t in the EU? On which parameter should I look while choosing the antenna to reach the best performance? please note that I am planning to use that in the elevator cabin where sometimes in my case in some buildings for example even phone cant catch GSM signal.

Thank you in advance.
