摘要

本文提出了一种简单的双宽带共孔径宽二维角扫描天线阵列。将一个工作在X波段的印刷偶极子天线单元和四个工作在Ku波段的微带准八木天线单元组合在一起，构建了一个用于相控阵的共享孔径超级单体。在基板上切割间隙以减少相邻元件之间的相互耦合。X波段和Ku波段元件均印刷在单层衬底上，实现了具有相同偏振的双宽带，同时结构简单。制作了由14 × 12 X波段单元和16 × 16 Ku波段单元组成的大型阵列拓扑进行验证。测量结果表明，该天线阵在X波段和Ku波段的带宽分别为11.8%和25%，同时具有−60°到+60°的较宽扫描角，增益下降小于5.1 dB。

A Simple Dual Wideband Shared-Aperture Antenna Array With Wide Scanning Angle

A simple dual wideband shared-aperture antenna array with wide 2-D angle scanning is proposed in this letter. One printed dipole antenna element operating in X band and four microstrip quasi-Yagi antenna elements operating in Ku band are combined to construct a shared-aperture supercell for the phased array. Gaps are cut on the substrate to reduce the mutual coupling between the adjacent elements. Both the X band and Ku band elements are printed on one-layer substrate to realize dual wide bands with the same polarization, meanwhile exhibiting a simple structure. A large array topology composed of 14 × 12 X band units and 16 × 16 Ku band units is fabricated for verification. Measured results show that the proposed antenna array has wide bandwidths of 11.8% in the X band and 25% in Ku band, meanwhile it has a relatively wide scanning angle ranging from −60° to +60° with the gain decrease less than 5.1 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.
