Abstract
This paper proposes an eleven-element series-fed microstrip antenna array design with a low sidelobe level (SLL) using modified tapering and wide azimuth field-of-view (FoV) using parasitic array loading at 79 GHz for automotive short-range RADAR (SRR) application. Here, we highlight the design limitation of conventional series-fed antenna arrays with the binomial tapering approach to reduce the SLL at 79 GHz. The proposed modified tapering approach provides 25 dB of SLL, nearly 80° azimuth FoV, and 13.1 dBi peak gain. Further, the parasitic array loading in the close vicinity of the proposed tapered array yields 68.75 improvement in azimuth FoV i.e., 135° and 46.8 improvement in impedance bandwidth with 22 dB SLL. © 2023 International Union of Radio Science.
