摘要

本文设计了一种在77 GHz频率下加载双层寄生叠加贴片的微带阵列天线，用于远程汽车雷达。阵列天线作为辐射源，寄生片作为导向，地面作为反射器。估计的指向性增强到22.87 dBi，比原微带阵列天线提高了3.16 dB。测得的半功率波束宽度在e面为8°，h面为22°，阻抗带宽在76.15 ~ 77.46 GHz之间，与仿真结果吻合较好。

A 77GHz High-Directivity Antenna with Stacked Patches for Automotive Radar

In this paper, a microstrip array antenna loaded with double-layer parasitic stacked patches is design at 77 GHz for the application of long-range automotive radar. The array antenna works as the radiation source, the parasitic patches work as directors and the ground operates as the reflector. The estimated directivity is enhanced to 22.87 dBi, 3.16 dB higher than the original microstrip array antenna. The measured half power beamwidth is 8° in E-plane and 22° in H-plane while the impedance bandwidth is from 76.15 to 77.46 GHz, which agree with the simulated results reasonably.
