Abstract

A single-layer substrate integrated waveguide (SIW) longitudinal slot array antenna with low sidelobe level (SLL) in H plan and wide beamwidth in E plan is presented for 77 GHz millimeter-wave angular radar applications. The radiation energy of the antenna is determined by the length and offset of the slot. The conductance of the slot that satisfies the Taylor distribution can effectively suppress the sidelobe of antennas. Measured results indicate that the SLL of the E plane is -28.5 dB, and the 3 dB beamwidth is 98.3°. A measured peak gain of 12.7 dB is observed with a -10 dB impedance bandwidth of 75.5 GHz~77.4 GHz. The measured results are in good agreement with the theoretical calculations, and the proposed antenna has been demonstrated as a promising candidate used for millimeter-wave automotive angular radar for the proposed antenna array.
