Advanced driver assistance systems (ADAS) technology has been developed to improve driver safety and is a major part of today's autonomous vehicle functionalities. Automotive radars operate as core sensors in modern ADAS systems since they can detect the speed and range of objects near the vehicle. This work uses a recent variant of the Runge-Kutta algorithm, namely RUN, to design an aperture-coupled antenna array for automotive radars. The proposed array consists of five U-shaped patch elements and achieves low return loss, high gain, and high efficiency at 77 GHz - 81 GHz.
