Abstract :
In this paper, we generate the zero-order Bessel beam at W band using a diagonal horn, a convex lens, and an axicon. The generated Bessel beam has smaller beam spot size than the Gaussian beam. Some imaging experiments with the generated zero-order Bessel beam are done. The results show that the millimeter wave imaging with the zero-order Bessel beam can get an imaging resolution of about 1mm to 2mm.
