Abstract

Current millimeter-wave (mm-Wave) endfire dielectric resonator antennas (DRAs) are limited to single polarization, highlighting the need for dual-polarized operation to fully leverage DRA advantages. Thus, in this letter, a compact dual-polarized endfire DRA array was proposed, and printed circuit board technology is used for high integration. The antenna element is initially designed to incorporate two orthogonal DRA modes, corresponding to vertical polarization (VP) and horizontal polarization (HP) for operation. Furthermore, to enhance the bandwidth of both polarizations, the corresponding cavity mode and slot mode are introduced, which are combined with the corresponding DRA mode for wideband work. VP and HP elements share the same structure, showing a compact size. Based on the element, a four-element array is designed and fabricated. The test results show that an overlapping bandwidth of 24.1 GHz to 29.6 GHz is realized. Besides, a peak gain of 10.3 dBi and 9.8 dBi for VP and HP is achieved, respectively. Moreover, both VP and HP enable beam scanning. From the above observed characteristics, it can be seen that the proposed design is promising for future 5G mm-Wave terminal applications.

5G毫米波终端用紧凑型双极化端射介质谐振器天线

目前的毫米波（mm-Wave）端射介质谐振器天线（DRAs）仅限于单极化，因此需要双极化操作来充分利用DRAs的优势。因此，本文提出了一种紧凑的双极化端射DRA阵列，采用印刷电路板技术实现高集成度。天线单元最初设计为包含两个正交的DRA模式，对应于垂直极化（VP）和水平极化（HP）进行工作。此外，为了提高两种极化的带宽，引入了相应的腔模式和槽模式，并与相应的DRA模式相结合，实现了宽带工作。VP和HP元件结构相同，尺寸紧凑。在此基础上，设计并制作了一个四元阵列。测试结果表明，实现了24.1 GHz ~ 29.6 GHz的重叠带宽。此外，VP和HP的峰值增益分别为10.3 dBi和9.8 dBi。此外，VP和HP都支持波束扫描。从以上观察到的特点可以看出，所提出的设计对于未来5G毫米波终端应用是有前景的。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
