Aspheric dielectric lens antenna for millimeter-wave imaging system


The imaging systems require low aberration and large depth of focus (DOF) to get an acceptable sharpness of the image. The lens antenna consists of a dielectric lens and an antenna array on the focus plane of the lens which has a great effect on the imaging quality of the system. In this paper, an aspheric biconvex lens with an aperture diameter of 430 mm… (More)
