提出了一种适用于在毫米波（mm-Wave）下操作的未来第五代（5G）移动的系统的极化可重构贴片天线。该天线由方形辐射单元、微带传输线馈电和两个独立偏置的PIN二极管组成。通过改变PIN二极管的状态，偏振类型在右旋圆偏振（RHCP）和左旋圆偏振（LHCP）之间切换。对所提出设计的仿真表明，天线工作频率为27.6至28.6 GHz，反射系数为−10 dB。在27.65-28.35 GHz频段上，在RHCP和LHCP状态下也实现了良好的轴比（小于3 dB）。简单的结构和易于制造使所提出的天线成为5G移动的应用的良好候选者。
A polarization reconfigurable patch antenna suitable for future fifth generation (5G) mobile systems operating at millimeter waves (mm-Wave) is presented. The proposed antenna consists of a square radiating element, microstrip transmission line feed, and two independently biased PIN diodes. The polarization type is switched between right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) by altering the states of the PIN diodes. Simulations of the proposed design demonstrate that the antenna operates from 27.6 to 28.6 GHz at −10 dB reflection coefficient level. A good axial ratio (less than 3 dB) is also achieved in both RHCP and LHCP states over the 27.65–28.35 GHz band. The simple structure and ease of fabrication make the proposed antenna a good candidate for 5G mobile applications.
