摘要
孔径耦合微带天线(ACMA)具有体积小、重量轻、成本低、集成简单等优点，是汽车雷达应用的理想选择。通常，它由两个基片组成，中间有一个导电地平面。所述贴片位于所述上基板的顶部，所述馈线位于所述下基板上。因此，这种天线避免了在某些情况下可能破坏副瓣电平的寄生线辐射。本通信介绍了用于79 GHz汽车雷达应用的多层孔径耦合微带天线(MACMA)的设计。该天线在接地面和贴片基板层之间夹有一层Rohacell HF 51泡沫。多层衬底用于最小化贴片天线之间的耦合，特别是由于泡沫介质材料的低综合介电常数，表面波在泡沫介质材料上不被显著激发。采用基于有限元法的三维全波电磁结构分析软件HFSS (High Frequency Structure Simulator)建立了MACMPA模型。
Design of a Compact Multilayered Aperture Coupled Microstrip Antenna for Automotive Range Radar Application
The aperture coupled microstrip antenna (ACMA) presents a good candidate for automotive radar application due to its compacity, light weight, low cost and the simplicity of its integration in antenna array. Typically, it consists of two substrates divided by a conductive ground plane in between. The patch is located on top of the upper substrate and the feedline is situated on the bottom substrate. Thereby, this antenna avoids parasitic line radiation which can, in some cases, disrupt side-lobe levels. This communication presents the design of a Multilayered Aperture Coupled Microstrip Antenna (MACMA) for 79 GHz automotive radar applications. This antenna presents in addition a Rohacell HF 51 foam sandwiched between the ground plane and the patch substrate layer. The multilayer substrate is used to minimize the coupling between patch antennas, in particular, surface waves which are not significantly excited on foam dielectric material thanks to the low synthetized permittivity. MACMPA model was done with High Frequency Structure Simulator (HFSS) software tool that could treat 3D full-wave electromagnetic structure analysis based on Finite Element Method.
