摘要

本文提出了一种宽带共面波导网格阵列天线。通过使用共面波导，天线阵列可以实现更宽的阻抗带宽为29% (21.69 - 29.04 GHz)。共面波导天线具有比传统微带网格天线更高的前后比。应用差分探针馈电可获得较低的交叉极化电平，约为-40 dB。共面波导天线的最大增益值为12.6 dBi。基于共面波导的天线具有低交叉极化、宽阻抗带宽、高增益和高前后比等优点，可以应用于5G毫米波通信中。

A Broadband Coplanar Waveguide Grid Array Antenna

In this paper, a broadband coplanar waveguide grid array antenna is presented. By using coplanar waveguide, the antenna array can achieve a wider impedance bandwidth is 29% (21.69 - 29.04 GHz). The coplanar waveguide-based antenna has a higher front-back ratio than the convention microstrip grid antenna. The differential probe feed is applied to get a lower cross-polarization level of about -40 dB. The coplanar waveguide-based antenna has the maximum gain value of 12.6 dBi. Due to these advantages of low cross polarization, wide impedance bandwidth, high gain and high front-back ratio, the coplanar waveguide-based antenna can be applied in the 5G millimeter wave communications.
