Abstract
ABSTRACTA broadband low profile magneto-electric dipole (ME-dipole) antenna is proposed which can control the steering of the antenna beam in the elevation plane and azimuth plane. A reflective phase gradient metasurface (RPGMS) is designed to act as the partially reflecting surface of the antenna and provides two different phase shifts for it. By rotating and translating RPGMS around the center of the antenna can reshape the wavefront shape, realize beam steering with directions (θ, ϕ)= (±40°, 0°), (±30°, 0°), (±20°, 0°), (±20°, 90°). The results of full wave simulation are in good agreement with the measured results, the beam tilted range of ± 40° in E-plane and ± 20° in H-plane are obtained at 8 GHz. The bandwidth is between 42.5% and 48.4%, with a maximum gain of 6.29dBi.KEYWORDS: Antennabeam controlbroadbandmetasurface Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the National Natural Science Foundation of China under project number 61701278.
期刊介绍：
Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance.
All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
