Design of Circularly Polarized End-fire Antenna on Gap Waveguide for Automotive Radar Application
Paper in proceeding, 2021
This paper presents an end-fire antenna with circu-lar polarization utilizing gap waveguide technology for 77 GHz automotive radar band. The proposed device contains a 1 × 4 planar array antenna and a gap waveguide part consisting of a 4-way power divider on ridge gap waveguide and a transitive groove gap waveguide. The impedance and 3-dB axial ratio bandwidths of 74.8 79.2 GHz and 75.6 78.0 GHz are achieved in simulation, which can cover the 77 GHz radar band well. A stable end-fire beam and a gain in the range of 11.6 to 13.4 dBic are obtained as well over the whole operation band.
