摘要

传统的里斯利棱镜天线通常是基于平面发射阵列天线，利用两层或三层可旋转发射阵列来实现二维波束扫描。为了减少发射阵列的层数，提出了一种结合反射阵列和发射阵列的新型里斯利棱镜天线。通过同时控制波的传输相位和偏振状态，可以将剖面减少到反射波的一半。此外，通过旋转发射阵列和反射阵列，实现了在二维平面上的圆极化波束扫描能力。此外，该天线具有宽扫描角、低轮廓、结构紧凑等特点，是无线通信系统的理想选择。

A Low-Profile 2-D Beam-Scanning Circularly Polarized Antenna Combining Reflectarray and Transmitarray

Traditional Risley-prism antennas are usually based on planar transmitarray antennas, utilizing two or three layers of rotatable transmitarrays to achieve 2-D beam scanning. To reduce the number of transmitarray layers, a novel Risley-prism antenna that combines a reflectarray and a transmitarray is proposed. By simultaneously controlling the transmission phase and polarization state of the waves, the profile can be reduced to only half that of a reflectarray. Additionally, by rotating both the transmitarray and the reflectarray, the circularly polarized beam-scanning capability in a 2-D plane is achieved. Moreover, the proposed antenna features a wide scanning angle, low profile, and compact structure, making it an excellent candidate for wireless communication systems.

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.
