Abstract
ABSTRACT In this paper, a series-fed microstrip antenna array with low sidelobe is presented for 24-GHz automotive radar. Chebyshev distribution is realized by different widths of a quarter-guided wavelength (λ g /4) feedline between adjacent antenna elements, achieving a low sidelobe level (SLL). A 1 × 8 antenna array is designed with the SLL of −23.1 dB at 24.125 GHz, which is extended to 2 × 8 and 8 × 8 planar arrays to improve array gain. The measured gain of 2 × 8 and 8 × 8 planar arrays is 17.3 dBi with an SLL of −23.6 dB and 22.1 dBi with an SLL of −24.7 dB at 24.125 GHz, respectively. In summary, the two antennas have excellent performance in the 24 GHz ISM band with the characteristics of good performance, simple structure, and easy integration, which can be applied to 24-GHz automotive radar.
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.
