High Isolated MIMO Antenna System for Full-Duplex 5G Applications
This paper presents a Multiple Input Multiple Output (MIMO) antenna system dedicated to the [3-4] GHz band for 5G Full-Duplex applications. The system is based on the association of 2 transmitting (Tx) patches arrays and 2 receiving (Rx) single patches positioned symmetrically and close to each other to achieve polarization/pattern diversity. Thus, an isolation greater than 30 dB is achieved in the whole band between the Tx and Rx antennas in simulations and measurements. Moreover, a high gain of 6.3 dBi is obtained for the Tx antennas and a total efficiency, greater than 70 %, is provided for both Tx and Rx antennas. These results, especially in terms of isolation, can be added to analog and digital cancellation techniques to satisfy the self-interference challenge of Full-Duplex systems, which is close to 100 dB of self-interference cancellation.
