Abstract

The invention discloses a millimeter-wave fan beam cylindrical Luneberg lens antenna based on a metal perturbation structure. The antenna achieves a pitch beam width reaching 104 degree and azimuth plane +/- 60 degree scanning. The antenna comprises a cylindrical Luneberg lens located between an upper metal flat plate (1) and a lower metal flat plate (2); an arc feed source array (3) located on the focal line of the cylindrical Luneberg lens; and the metal perturbation structure (5) arranged on the radiating aperture of the lens circumferentially. The cylindrical Luneberg lens comprises a cylindrical filling dielectric sheet (4). The filling dielectric sheet uses a low-loss microwave substrate as a substrate material and is divided into five layers according to a concentric circle structure from inside to outside. Respective layers have through-holes with different densities. The through-holes are filled with air. The antenna is light in weight and easy to process, greatly increases the pitch surface beam width, realizes a wide beam scanning range in the horizontal plane so as to be better applied to a multi-beam directional communication and beam scanning antenna, especially the millimeter wave high-frequency band and applications requiring axial grouping.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a lens antenna system for wide-angle scanning, in particular to a millimeter-wave fan-shaped beam cylindrical Lunberg lens antenna based on a metal perturbation structure, which can be used for electronic platforms requiring wide-angle scanning. Background technique [0002] As an important branch of modern antennas, multi-beam antenna (MBA) has been widely used in radar systems, electronic countermeasures and Satellite communications and other technical fields. [0003] At present, the most common multi-beam antennas mainly fall into three categories: multi-beam reflector antennas, multi-beam phased array antennas, and multi-beam lens antennas. With the rapid development of millimeter wave communication systems, the requirements for antenna scanning and beam coverage capabilities in shipboard, airborne and base station systems are getting higher and higher. In the millimeter-...
