Summary:
This paper presents a dual-band MIMO array antenna working in LTE frequency band. A dual-band PIFA antenna is used for every single antenna element. The PIFA antenna is achieved by using the slotted technology. Using coupling feed and adding a capacitive patch to the short wall to reduce the coupling between two antenna elements can improve the isolation of the MIMO system. The designed antenna can work on the LTE 2.3GHz and LTE 2.6GHz bands synchronously, corresponding band widths are 2300MHz-2400MHz and 2570MHz-2620MHz respectively. Simulation results show that within the operating frequency bands, isolation can be less than - 25dB without significantly affecting the radiation characteristics, which demonstrates the feasibility of this design.
