Is the reason for same input power to the MIMO antenna while its design in CST is so due to its passive nature???. Since, the antenna is not smart enough to know the channel state information (CSI). If the designed MIMO antenna is smart antenna then it is abled to know the CSI so that high power is allocated to the channel path which is expected to improve the throughput.??????? Is that so the reason for same input input power fed to MIMO antenna with MxM elements in it.
