提出了一种用于2G/3G/LTE基站应用的简单差分增强宽带双极化印刷偶极子天线。该天线包含两个正交的方形振子和一个新颖的方形馈电结构，以实现宽带宽，以及一个平面反射器，以形成辐射方向图。由于采用差分馈电和理想对称结构，天线可以分别实现低交叉极化水平和高端口到端口隔离度。测试结果表明，该天线在驻波比小于1.5时带宽为67.5%，差分端口到端口隔离度优于−40 dB，E面和H面的半功率波束宽度（HPBW）分别为68.7° ± 4.2°和68.3° ± 4.9°，在1.65 ~ 3.33 GHz范围内天线增益稳定在7.8 ± 1 dBi。在工作带宽内，主瓣内交叉极化比保持在−25 dB以上，前后比保持在31 dB以上。© 2016 Wiley Periodicals，Inc.微波光学技术快报58：2864-2868，2016
A simple differential enhanced broadband dual‐polarized printed dipole antenna for 2G/3G/LTE base station applications is presented. The proposed antenna contains two orthogonal square‐shaped dipoles and a novel square‐shaped feeding structure to achieve a wide bandwidth, and a planar reflector to shape radiation patterns. Due to adopting the differential feeding and ideally symmetrical structure, the antenna can achieve low cross‐polarization level and high port‐to‐port isolation, respectively. Measured results show that the proposed antenna achieves a bandwidth of 67.5% for SWR < 1.5, differential port‐to‐port isolation better than −40 dB, stable half‐power beam width (HPBW) 68.7° ± 4.2° at E‐plane and 68.3° ± 4.9° at H‐plane, and a stable antenna gain of 7.8 ± 1 dBi from 1.65 to 3.33 GHz. The cross‐polarization ratio within the main lobe remains over than −25 dB, and the front‐to‐back ratios keep higher than 31 dB over the operating bandwidth. © 2016 Wiley Periodicals, Inc.
