Abstract

A novel metal wall-loaded comb-shaped wide beam array antenna is proposed to meet the application requirements of short-range automotive millimeter wave radar with wide field of view coverage. The antenna is composed of 8 elements with slots connected in series, and two identical metal walls are set on both sides of the elements. Through the implementation of tight coupling techniques between patch elements and the strategic integration of monopole-like metal walls, the antenna's impedance bandwidth and beamwidth have been significantly augmented. To elucidate the beam broadening mechanism, a comprehensive analysis of the proposed antenna has been conducted utilizing the equivalence principle. Simulation and measurement results demonstrate that the proposed antenna achieves a bandwidth exceeding 5 GHz, encompassing the 76 GHz–81 GHz automotive radar band. Meanwhile, the antenna radiates a distinctive saddle-shaped beam with a beamwidth surpassing 148° and a gain of 10 dBi. The wide beamwidth characteristic of this antenna not only fulfills the requirements for short-range radar applications but also exhibits substantial potential for extension into medium- and long-range detection radar applications.

一种用于近程雷达的新型串馈宽波束梳状阵列天线

为满足近程汽车毫米波雷达大视场覆盖的应用需求，提出了一种新型金属壁载梳状宽波束阵列天线。天线由8个槽串联的单元组成，单元两侧设置两个相同的金属壁。通过实施贴片元件之间的紧密耦合技术和单极金属壁的战略性集成，天线的阻抗带宽和波束宽度得到了显著提高。为了阐明波束展宽机理，利用等效原理对该天线进行了综合分析。仿真和测量结果表明，该天线的带宽超过5 GHz，覆盖了76 GHz - 81 GHz的汽车雷达频段。同时，天线辐射出独特的鞍形波束，波束宽度超过148°，增益为10 dBi。该天线的宽波束宽度特性不仅满足了近程雷达应用的要求，而且显示出扩展到中远程探测雷达应用的巨大潜力。
