Abstract

An airborne conformal bearing antenna of the present invention comprises a reflecting plate, a microstrip antenna, a radio frequency connector and a skin, wherein the reflecting plate is of a bearing structure, and the inner side of the reflecting plate is provided with a rear-end device and a fixing interface of the radio frequency connector; the microstrip antenna is fixed at the outer side of the reflecting plate; the skin has a wave-transparent function and is laid at the outer side of the microstrip antenna, and the appearance of the skin is consistent with the aerodynamic appearance of an airplane. After integral forming, the mechanical connection between the conformal antenna and an aircraft structure is realized through the installation holes in the reflecting plate. The airborne conformal bearing antenna has excellent structural rigidity, and the aperture of the airborne conformal antenna can be remarkably improved; the antenna has the capability of hanging a rear-end active device, reduces the loss between the rear-end active device and the antenna, and further improves the power of a detection system.

Description

technical field [0001] The invention relates to the technical field of antenna structures, in particular to an airborne conformal bearing antenna. Background technique [0002] The conformal antenna refers to the array antenna attached to the surface of the carrier and bonded to the carrier, that is, the array antenna needs to be conformally installed on a fixed-shaped surface to form a non-planar conformal antenna array. [0003] Compared with planar antennas, conformal antennas have the following advantages: [0004] 1) Improve radar wide-angle scanning performance; [0005] 2) Eliminate or reduce the aiming error caused by the radome; [0006] 3) The antenna can be conformally placed at any position of the carrier to achieve full spatial coverage of the pattern. [0007] Airborne radar has the advantages of long detection distance and long warning time. Aircraft is currently the most widely used carrier for conformal antennas, because conformal antennas can eliminate t...
