With the development of Internet and 3G communication systems, the requirement of data transmission is increasing. Multi-Input-Multi-Output (MIMO) as one of the important techniques to improve the capacity of Long Term Evolution (LTE) systems have been widely discussed. However, how to deploy MIMO for indoor scenarios is still a problem which needs to be solved at present. In this paper, dual-path single-polarized antenna and dual-path dual-polarized antenna solutions are analyzed. According to simulation and test results, under appropriate indoor scenarios, the both solutions have good coverage performance and have 56% improvement in capacity performance compared with traditional single-path single-polarized antenna solution.
