An antenna for generating an arbitrarily directed Bessel beam, including a beam-forming plane and a feeding horn, the beam-forming plane is a dual-layer dielectric substrate structure having a beam focusing function, including: a printed circuit bottom layer, a high-frequency dielectric substrate lower layer, a printed circuit middle layer, a high-frequency dielectric substrate upper layer, and, a printed circuit upper layer; the printed circuit bottom layer, the high-frequency dielectric substrate lower layer, the printed circuit middle layer, the high-frequency dielectric substrate upper layer, and the printed circuit upper layer are co-axially stacked from the bottom to the top: the beam-forming plane is entirely divided into periodically arranged beam-forming units by a plurality of meshes, and each beam-forming unit consists of printed circuit upper, middle and lower metal patches of which centers are on the same longitudinal axis, the high-frequency dielectric substrate lower layer and the high-frequency dielectric substrate upper layer.
