A review on circular polarization antenna for wireless MIMO application

This paper will review the development of wireless MIMO communication system and the circular polarization antenna. It is impossible to fulfil the demand of the wireless communication system due to limitations in channel capacity on single input single output (SISO) systems. Multiple input multiple output (MIMO) system has become a famous research field for the next generation wireless communication system in order to overcome this problem. Since polarization diversity is effective to avoid the fading loss caused by multipath effects, therefore, polarization diversity becomes one of the most important techniques that can be used to enhance MIMO system performances. It can be utilized to improve the communications channel capacity and utilize the frequency spectrum with frequency reuse technique. Therefore, the development of polarized antenna is significant in order to improve the wireless MIMO system performance based on polarization diversity technique.
