With the fast adoption of LTE and IEEE 802.11N,in order to increase the maximum data rate of a system and to make the communication link more reliable most of the devices are employing multiple antennas.Traditionally,fixed antennas are used in such devices.Nowadays,reconfigurable antenna are designed for the purpose of further increase the performance,which maintain or exceeds the performance of fixed antenna,and by changing their radiation characteristics can adopt to changing wireless channel....
