摘要

本文提出了一种基于毫米波雷达的宽带微带阵列天线，以实现对高炉炉料表面的强抗干扰能力和高分辨率探测。该天线由切比雪夫主辐射贴片阵列和纽扣形共面寄生元件阵列组成。共面寄生元件改变了天线贴片之间的耦合，从而拓宽了带宽。它改善了以往毫米波阵列天线因带宽不足而对角分辨率的限制。仿真结果表明，−10 dB阻抗带宽为7.89 GHz，天线主增益达到13.92 dBi。该天线适用于高增益和高抗干扰毫米波雷达系统，尺寸大大减小，约为20毫米，适用于放置在高炉探测系统的保护舱内。它在解决与内部环境对高炉运行的影响有关的问题方面具有很大的潜力。

Design of Millimeter Wave Radar Broadband Microstrip Antenna for Blast Furnace

In this paper, a wideband microstrip array antenna based on millimeter-wave radar is proposed, to achieve strong anti-interference ability and high resolution for detecting the burden surface of blast furnaces. The antenna consists of a Chebyshev main radiation patch array and a button-shaped coplanar parasitic element array. The coplanar parasitic elements alter the coupling between antenna patches to widen the bandwidth. It improves the limitation of the angular resolution of the previous millimeter-wave array antenna due to the problem of insufficient bandwidth. Simulation results show that the −10 dB impedance bandwidth is 7.89 GHz and the antenna main gain reaches 13.92 dBi. The antenna is suitable for high-gain and high anti-interference millimeter-wave radar systems and has greatly reduced dimensions of approximately twenty millimeters, making it applicable for placement in the protective cabin of a blast furnace detection system. It has great potential for solving issues related to the impact of internal environments on blast furnace operations.
