中文摘要：

根据对物体毫米波信号采集的需要,设计一种工作于8 mm频段的点聚焦透镜天线,选用宽波束微带天线做馈源,设计焦距大小不同的双面透镜,采用电磁仿真软件CST对聚焦透镜天线进行仿真实验,从仿真结果可以看出,不同焦距双面透镜实现了预期聚焦效果且空间分辨率大小能够满足对物体逐点扫描的需求。

英文摘要：

A point-focusing lens antenna working at 8 mm frequency band was designed according to the demand for millimeter-wave signal acquisition. The double-sided lens with different focal lengths was designed by selecting the wide beam microstrip antenna as the feed source. The electromagnetic simulation software CST is used to simulate the focusing lens antenna.The simulation results show that the double-sided lens with different focal lengths can realize the expected focusing effect and high spatial resolution,which can meet the demand for point-by-point scanning of the object.
