Abstract

ABSTRACT In this paper, a series-fed microstrip antenna array with low sidelobe is presented for 24-GHz automotive radar. Chebyshev distribution is realized by different widths of a quarter-guided wavelength (λ g /4) feedline between adjacent antenna elements, achieving a low sidelobe level (SLL). A 1 × 8 antenna array is designed with the SLL of −23.1 dB at 24.125 GHz, which is extended to 2 × 8 and 8 × 8 planar arrays to improve array gain. The measured gain of 2 × 8 and 8 × 8 planar arrays is 17.3 dBi with an SLL of −23.6 dB and 22.1 dBi with an SLL of −24.7 dB at 24.125 GHz, respectively. In summary, the two antennas have excellent performance in the 24 GHz ISM band with the characteristics of good performance, simple structure, and easy integration, which can be applied to 24-GHz automotive radar.

一种用于24ghz汽车雷达的串联馈电低旁瓣天线

提出了一种用于24ghz汽车雷达的低旁瓣串联馈电微带天线阵列。切比雪夫分布是通过相邻天线单元之间不同宽度的四分之一波导波长馈线(λ g /4)来实现的，从而实现低旁瓣电平(SLL)。设计了一种1 × 8天线阵列，24.125 GHz时SLL为−23.1 dB，并将其扩展到2 × 8和8 × 8平面阵列，以提高阵列增益。在24.125 GHz下，2 × 8和8 × 8平面阵列的测量增益分别为17.3 dBi, SLL为- 23.6 dB; 22.1 dBi, SLL为- 24.7 dB。综上所述，两根天线在24 GHz ISM频段性能优异，具有性能好、结构简单、易于集成的特点，可应用于24 GHz汽车雷达。
