A new wideband CP antenna with a single-layer metasurface
ABSTRACT In this paper, a new wideband circularly polarized (CP) antenna with a single-layer metasurface (MT) is developed. The single-layer MT consists of 4 × 4 truncated corner square patch cells with corner-cut square slots. Compared to the single truncated corner square patch, introducing corner-cut square slot can increase the design flexibility by changing the slot size for a wider CP operating bandwidth. A slit-shaped aperture coupling structure and a microstrip fed structure are placed together to provide coupling energy to the MT. Note that such MT and slot antenna share the same reference ground plane, and there is no air gap among the overall CP antenna structure. This design could easily make the profile low and the structure compact. The tested results reveal that the presented antenna features a broad 3-dB axial ratio bandwidth (18.2%, 5.25 ~ 6.3 GHz) and a wide −10-dB impedance bandwidth (19%, 5.25 ~ 6.35 GHz), which is very suitable for wireless communication systems with low-profile and wideband requirements.
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.
