Abstract

A single feed grid array antenna for 24 GHz Doppler sensor is proposed in this paper. It is designed on 0.787 mm thick substrate made of Rogers Duroid 5880 (ε_r= 2.2 and tan δ= 0.0009) with 0.017 mm copper claddings. Dimension of the antenna is 60 mm × 60 mm × 0.787 mm. This antenna exhibits 2.08% impedance bandwidth, 6.25% radiation bandwidth and 20.6 dBi gain at 24.2 GHz. The beamwidth is 14°and 16°in yoz and xoz planes, respectively.

用于24 GHz多普勒传感器的微带网格阵列天线

提出了一种用于24ghz多普勒传感器的单馈电栅格阵列天线。它被设计在0.787 mm厚的基片上，基片由罗杰斯Duroid 5880 (εr= 2.2, tan δ= 0.0009)制成，并包覆0.017 mm的铜。天线尺寸为60mm × 60mm × 0.787 mm。该天线在24.2 GHz时阻抗带宽为2.08%，辐射带宽为6.25%，增益为20.6 dBi。在yz面和xoz面，波束宽度分别为14°和16°。
