摘要

带阶梯式衍射介质透镜的初级锥体喇叭已被设计用于周界雷达，以在77GHz左右的频率范围内形成所需的辐射模式。对该结构的全波仿真表明，该结构的指向性得到了改善，旁瓣电平(SLL)得到了降低，这是雷达应用所必需的。35 dBi或更高的指向性和- 17 dB或更低的SLL是该结构的目标，并且已经实现。

A 77 GHz stepped diffractive dielectric lens with enhanced directivity and reduced SLL

Primary pyramidal horn with a stepped diffractive dielectric lens has been designed to be used in a perimeter radar to shape the required radiation pattern in a band of frequency around 77GHz. A full-wave simulation for this structure indicates directivity improvement and side lobe level (SLL) reduction which is necessary for radar applications. A directivity of 35 dBi or higher and SLL of −17 dB or less have been the goals of the proposed structure and are fulfilled.
