Hi
I think u should design antenna by form yourself. If u want to find some example about antenna, I think u should find it in IEEE websize. Antenna use in smart phone, I think it's secrret of all vendor.

Any USB GSM/3G/4G modem or cell phone, if it have a FCC certification number can you find photos of the antennas at www.fcc.com.
Dominating type of antenna is multiband PIFA for both modem and cell phones regarding this type of wide band internet connection.
