Design and Implementation of an Antenna for Automotive Applications at 76.5 Ghz

Abstract

This paper presents an antenna candidate for automotive cars and MIMO radar applications. It is implemented on Rogers RO4003C with a relative dielectric constant of 3.55 and a thickness of 0.203 mm. Linearly and circularly polarized versions of printed antennas are presented and operate at 76.5 GHz, which meets the characteristics of the required application. One of the antennas is selected and fabricated for validation. The results of the reflection coefficient fo und good agreement between the simulated and measured ones. Further antenna parameters like 3D and 2D radiation patterns, realized gain and axial ratio are illustrated. © 2024 IEEE.
