Abstract

This letter proposes a compact millimeter-wave (mmWave) planar antenna array with wideband and wide-angle scanning capabilities. The proposed design incorporates a segmented patch to extend the bandwidth and utilizes metal vias to suppress nonradiative mode. A substrate-integrated back cavity structure is introduced to suppress surface waves, improving wide-angle impedance matching (WAIM) in the E-plane. In addition, a square-ring meta-surface enhances WAIM in the H-plane. A fabricated 6 × 6 array demonstrates a bandwidth of 23.16 GHz to 29.28 GHz (23.3%) and scanning ranges of

$\bm {\pm 70^\circ }$

in the E-plane and

$\bm {\pm 60^\circ }$

in the H-plane, providing a viable pathway for compact mmWave systems requiring concurrent wideband and wide-angle scanning.

小型宽频带广角扫描毫米波平面天线阵

这封信提出了一种紧凑的毫米波（mmWave）平面天线阵列，具有宽带和广角扫描能力。所提出的设计包含一个分段贴片来扩展带宽，并利用金属通孔来抑制非辐射模式。采用基片集成后腔结构抑制表面波，改善e平面的广角阻抗匹配（WAIM）。此外，方形环元曲面增强了h平面的WAIM。所制备的6 × 6阵列的带宽为23.16 GHz ~ 29.28 GHz (23.3%)， e面扫描范围为$\bm {\pm 70^\circ}$， h面扫描范围为$\bm {\pm 60^\circ}$，为需要同时进行宽带和广角扫描的紧凑毫米波系统提供了可行的途径。

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.
