Abstract

The invention discloses a compact type millimeter-wave monopulse antenna and belongs to the technical field of antennas. The compact-type millimeter-wave mmonopulse antenna comprises a feed source, a main reflecting surface, an auxiliary reflecting surface, a supporting structure and a sum-difference network. Both the main reflecting surface and the auxiliary reflecting surface adopt plane reflection array antennas, and the sum-difference network is of a plane structure. Compared with a traditional monopulse antenna, the compact type millimeter-wave monopulse antenna has the advantages of small size, light weight and proneness to connection with other integrated high-frequency components.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a compact millimeter-wave monopulse antenna, which can be used to reduce the volume and quality of traditional monopulse antennas and improve the integration of monopulse antennas and systems. Background technique [0002] Millimeter wave belongs to the wavelength range where microwave and far-infrared waves overlap. It has three characteristics: unique atmospheric transmission characteristics, available frequency bandwidth and short millimeter wave wavelength. The unique atmospheric transmission characteristics make the attenuation of the millimeter-wave antenna small when propagating through the atmospheric window, and are less affected by natural light and heat radiation sources; the available frequency bandwidth is beneficial to the millimeter-wave antenna to reduce multipath effects and suppress clutter effects, and enhance the anti-interference ability of the sy...
