Active conformal array antenna applied to unmanned aerial vehicle platform

Abstract

The invention discloses an active conformal array antenna applied to an unmanned aerial vehicle platform, and sequentially comprises an antenna array surface, a body skin, a multifunctional board, anda tile-type TR assembly that are integrated and conformal from the outside to the inside, a patch is adopted as a radiation unit on the antenna array surface and is conformal with the structure of the body skin, wherein the antenna array surface comprises an antenna radiation layer, and a thermal control and support layer which are sequentially arranged from the outside to the inside, the antennaarray surface adopts an SMP blind matching connector to penetrate through the thermal control and support layer and the multifunctional board to be connected with the tile-type TR component. According to the invention, the integrated integration of the active module, the antenna array and the body skin is realized by combining rigid and flexible printed boards, the defects that a traditional design cannot realize the integrated integration of the active module and the body are overcome, and meanwhile, the occupied space is small, the anti-electromagnetic interference resistance is strong, andthe aerodynamic requirements of the aircraft is met.

Description

technical field [0001] The invention relates to the technical field of radar antennas, in particular to an active conformal array antenna applied to an unmanned aerial vehicle platform. Background technique [0002] A large number of single-function antennas are used on modern aircraft, which are installed around the aircraft. They mainly serve electronic equipment such as radars, electronic warfare receivers, jammers, missile incoming warning equipment, navigation equipment, and radar altimeters. These antennas are generally distributed in The aircraft head, above or below the front, and covered with a radome. With the development of future aircraft in the direction of miniaturization, light weight, and unmanned, the requirements for the volume, weight, and performance of electronic systems are becoming more and more stringent, especially for airborne, spaceborne, and various weapon systems. The required electronic components and components are developing rapidly in the di...
