摘要

本文提出了一种工作在x波段的二维圆极化Van Atta阵列。针对具有圆形阵列表面的应用，首次引入了圆形部署。与传统的方形布局相比，这种布局允许更多的数组元素和更好的对称性。基于这种循环部署，完成了24元Van Atta阵列相位共轭网络设计。网络层为单层，保证了传输线之间的相位差小于9.45$^\circ$。它在单站雷达截面（RCS）的正交方向上表现出良好的增强效果。测量的归一化单稳态RCS - 10 dB波束宽度在9.4 GHz为106$^\circ （\varphi =0^{\circ}$）和94$^\circ (\varphi =90^{\circ}$)，在9.7 GHz为109$^\circ （\varphi =0^{\circ}$）和105$^\circ (\varphi =90^{\circ}$)，在10 GHz为99$^\circ （\varphi =0^{\circ}$）和93$^\circ (\varphi =90^{\circ}$)，与模拟结果吻合较好。

A 2-D Planar Circularly Polarized Van Atta Retrodirective Array With Highly Symmetrical Circular Structure for RCS Enhancement

A 2-D circularly polarized Van Atta array operating in the X -band is proposed in this letter. Targeting applications with circular array surfaces, a circular deployment is introduced for the first time. Compared to conventional square deployments, this arrangement allows for more array elements and better symmetry. A 24-element Van Atta array phase conjugate network design is completed based on this circular deployment. The network layer is single layered, ensuring that the phase difference between transmission lines is less than 9.45

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.
