Abstract
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.
