摘　　要：In this paper, a wideband high gain millimeter wave radar array antenna based on a wavy power divider was proposed. The radar antenna comprises a wavy power divider and a 10-element array antenna. By adjusting the wavy radius of the power divider, the surface current of the power divider is altered, resulting in better impedance matching with the antenna. This ultimately leads to a significant improvement in bandwidth performance. The 4×10 millimeter wave radar antenna loaded with a wavy power divider exhibits an approximate enhancement of 3 GHz compared to traditional microstrip power divider antennas, and an average gain increase of 2.42 dB within the vehicle millimeter wave radar frequency band relative to the improved gradient power divider structure. The 4×10 millimeter wave radar antenna loaded with wavy power divider possesses the characteristics of high gain and broad bandwidth.
