摘要

本文提出了一种适用于毫米波应用的紧凑平面全量程开关波束网格阵列天线(GAA)。通过正确定位馈电点，GAA能够产生具有特定覆盖范围的全范围开关波束，例如，具有17个馈电口的GAA在93 GHz时产生17个立体角为θ = 14.1°至26.3°的波束，指向性范围为15.3 dBi至18.3 dBi。对于77 ghz智能汽车雷达应用，GAA可以产生4波束，扫描范围为±15°，峰值增益>18 dBi。低成本印刷电路板(PCB)上的GAA具有极其紧凑的结构，即其尺寸为传统发射阵列的1/70。

Millimeter Wave Planar Full-range Switched Beam Grid Array Antenna and its Smart Car Radar Applications

In this paper, a patented compact planar full-range switched beam grid array antenna (GAA) is proposed for millimeter wave applications. By positioning the feeding points properly, the GAA is able to generate full-range switched beams with a specific coverage, for example, a GAA with 17 feeding ports generates 17 beams within a solid angle of θ = 14.1° to 26.3° with the directivity range from 15.3 dBi to 18.3 dBi at 93 GHz. For the 77-GHz smart car radar application, the GAA can produce 4 beams with ±15° scanning range and peak gain >18 dBi. The GAA on low cost printed circuit board (PCB) is with extremely compact structure, namely, its size is 1/70 of a conventional transmit-array.
