Abstract

This letter proposed a dual-polarized tightly coupled dipole linear array (TCDLA) with high cross-polarization discrimination (XPD). Building upon conventional TCDLA architectures, this work develops enhanced configurations through capacitive coupling structures and matching material loading to broaden operational bandwidth. A dual-layer ground structure is implemented to achieve lower profile characteristics. For the first time, an interleaved array configuration is proposed to address the inherent poor XPD caused by asymmetric array distribution in conventional TCDLA. At last, 5.7:1 bandwidth ratio (0.35 GHz to 2 GHz) with 60° maximum scan angle is obtained by the proposed antenna, and its XPD exceeds 20 dB across the entire operating band.

一种低姿态高交叉偏振分辨紧密耦合偶极子线性阵列

本文提出了一种具有高交叉极化分辨力（XPD）的双极化紧密耦合偶极子线性阵列（TCDLA）。在传统TCDLA架构的基础上，本研究通过电容耦合结构和匹配材料负载开发了增强的配置，以扩大操作带宽。采用双层地面结构实现低轮廓特性。针对传统TCDLA中由于阵列分布不对称而导致的XPD性能较差的问题，首次提出了交错阵列结构。最后，该天线在最大扫描角为60°的情况下，获得了5.7:1的带宽比（0.35 GHz ~ 2 GHz），整个工作频带的XPD均超过20 dB。

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.
