Q.Why polarization is needed in the GSM antenna? What would happen if there were no electrical and mechanical polarization?
A.To avoid space diversity,Now a days crosspolarised(90* pol. difference b/w TX & RX) GSM antennas are used which can simultaeously work as a TX and RX both,without interference.
