Increasing channel capacity on MIMO system employing adaptive pattern/polarization reconfigurable antenna

This paper presents a pattern/polarization reconfigurable single turn square spiral microstrip antenna that is designed to operate in the 5 GHz indoor band and tested with Intel-developed CMOS MIMO transceivers. Experimental results show that different environments between transmitter and receiver antenna MIMO system require different antenna configurations to achieve lower correlation between paths and increase the throughput.
