Design of a Millimeter Wave Radar Microstrip Array Antenna System

本文设计了一种77 GHz毫米波雷达收发微阵列天线系统,阐述了微带阵列天线模型设计、微带阵列天线布局设计和微带阵列天线罩设计,并对微带阵列天线进行了三维电磁仿真。仿真实验结果显示,在较小的外壳及较小的电路板尺寸下,设计的毫米波雷达微带阵列天线系统具有较高的增益、较低的副瓣电平以及较宽波束的特性,具有较好的电磁波收发效果,能够满足汽车雷达对天线性能的指标要求。

This paper designs a 77 GHz millimeter wave radar transceiver micro array antenna system,describes the design of microstrip array antenna model,microstrip array antenna layout design and microstrip array radome design,and carries out threedimensional electromagnetic simulation of the microstrip array antenna.The simulation results show that the millimeter wave radar microstrip array antenna system designed in this paper has the characteristics of higher gain,lower side lobe level and wider beam under the condition of smaller shell and smaller circuit board size,and has better electromagnetic wave transceiver effect,which can meet the performance requirements of automotive radar antenna.
