摘要

提出了一种适用于5G毫米波终端应用的宽带差分驱动双极化磁电偶极子天线。设计了十字形带材差动进料结构，实现了高的口对口隔离，同时降低了型材高度。为了进行概念验证，对所提出的天线进行了研究、实现和测量。测量结果表明，该天线具有60.9% (24.2-45.4 GHz)的宽重叠阻抗带宽，在工作频带上具有优于30 dB的高隔离度。除了宽带带宽外，具有稳定的增益和辐射方向图、低交叉极化水平和大前后比(FTBR)等具有前景的辐射特性，对实际应用具有重要意义。

A Wideband Differentially-Driven Dual-Polarized Antenna for 5G mmWave Terminal Application

A wideband differentially-driven dual-polarized magneto-electric (ME) dipole antenna suitable for 5G mmWave terminal application is presented in this paper. A cross-shaped strip differential feeding structure is designed to achieve the high port-to-port isolation and meanwhile reduce the profile height. For proof-of-concept demonstration, the proposed antenna is investigated, implemented and measured. The measurement results of the antenna show a wide overlapped impedance bandwidth of 60.9% (24.2-45.4 GHz) and the high isolation of better than 30 dB over the operating band. Apart from the broadband bandwidth, promising radiation characteristics including stable gain and radiation pattern, low cross-polarization level and large front-to-back ratio (FTBR) are of significance to practical applications as well.
