摘要

串联馈电微带贴片天线阵列以其结构简单、高增益、低成本等优点被广泛应用于毫米波雷达中。然而，它们的阻抗带宽通常很窄。本文提出了一种具有带宽增强和旁瓣抑制功能的79GHz串联馈电微带贴片天线阵列。仿真结果表明，E-Plane和H-Plane最大旁瓣电平分别为-19dB和-17dB， -10dB阻抗带宽为4.14GHz，高增益为22dBi。

A 79GHz Series Fed Microstrip Patch Antenna Array with Bandwidth Enhancement and Sidelobe Suppression

Series fed microstrip patch antenna arrays are widely used for millimeter-wave radar applications due to their simple structure, high gain, and low cost. However, they usually suffer from narrow impedance bandwidth. In this paper, a 79GHz series fed microstrip patch antenna array with bandwidth enhancement and sidelobe suppression is presented. The obtained simulation results showed a maximum sidelobe level of -19dB and -17dB at E-Plane and H-Plane, respectively, as well as a -10dB impedance bandwidth of 4.14GHz and a high gain of 22dBi.
