Aperture-coupled Bowtie Patch Antenna Design for Autonomous Driving Applications

Autonomous driving will reshape transportation networks, offering at the same time many benefits such as safety, reliable vehicle-to-vehicle communication, and extended telecommunications. For a self-driving vehicle to navigate freely and perceive its environment, it is necessary to be equipped with many sensors. Automotive radars and antenna arrays that operate at 76-81 GHz have been proposed as key elements in future autonomous vehicles. In this work, an aperture-coupled bowtie antenna is designed utilizing hunger games search optimization. The proposed element achieves quite satisfactory values of return loss and gain, as well as broadband operation at 76 GHz - 81 GHz.
