摘要

提出了一种面向5G无线通信系统的全双工可重构方向图系统天线设计方案。所提出的系统是一个MIMO 2 $\times$ 2天线，工作在LTE2500频段的中心频率2.622 GHz。采用正交3db耦合器实现可配置性。所提出的耦合器还允许具有58 dB的高隔离，这是全双工通信所需的。通过四种组合得到四种模式配置。该天线带宽为65 MHz，效率为80%，增益为4.18 dB。

Full Duplex and Pattern Reconfigurable System Antenna Design for 5G Wireless Communications Systems Using a Quadrature 3 dB Coupler

This paper presents a full duplex and reconfigurable pattern system antenna design for 5G wireless communications systems. The proposed system is a MIMO 2 $\times$ 2 antenna operating at the central frequency 2.622 GHz of the LTE2500 band. A quadrature 3 dB coupler is used to achieve configurability. The proposed coupler allows also to have a high isolation of 58 dB needed for Full Duplex communication. Four patterns configurations are obtained with four combinations. The proposed antenna has 65 MHz bandwidth, 80% efficiency and achieve 4.18 dB of gain.
