摘要：
This paper proposes a 77GHz microstrip series-fed patch antenna array for automotive radar applications. Based on the Taylor Distribution Principle, we designed a six-unit series-fed weighted antenna array. A Wilkinson 1 : 8 un-equal divider is employed to connect eight antenna arrays to form a whole planar antenna. In antenna far-field patterns, the E-plane side-lobe level is approximately below -20.15 dB, and the H-plane side-lobe level is about -15 dB. Good accordance is obtained between simulated and measured results. The designed antenna has great value in the application fields of 77 GHz automotive radar antenna.
