摘要

本研究开发了一种适用于汽车雷达的24 ghz 1 × 8贴片天线阵列。所提出的宽波束天线阵列在仰角上具有窄波束宽度，在方位角上具有宽波束宽度。串联补片的构造和横向加载寄生条。寄生条的电流方向与贴片电流方向相反，导致增益抵消和h面辐射图中的宽波束宽度。实验证明，该设计实现了13.5 dBi增益和100°宽波束宽度。

24-GHz Wide-Beam Patch Antenna Array Laterally Loaded With Parasitic Strips

This study develops a 24-GHz 1 × 8 patch antenna array for automotive radar applications. The proposed wide-beam antenna array can offer a narrow beamwidth in elevation and a wide beamwidth in azimuth. The series-fed patches are constructed and laterally loaded with parasitic strips. The current direction of the parasitic strips is opposite to the patch current, resulting in gain cancelation and wide beamwidth in the H-plane radiation pattern. The experimental demonstration showed the proposed design achieved a gain of 13.5 dBi and a wide beamwidth of 100°.
