The MIMO antenna design for a TD-LTE mobile phone

TD-LTE mobile communication systems use MIMO technology. In this paper, a mobile phone MIMO antenna design with two elements having high isolation is presented. The antenna can work in 2300/2500MHz frequency bands. The method of distance isolation is used to reduce the coupling between the two antenna elements. HFSS is used in the simulation analysis and optimization of the antenna. Test results show that antenna return loss, gain and isolation between the two elements meet the TD-LTE phone needs.
