Wing antenna integrating structures and functions

Abstract

The invention discloses a wing antenna integrating structures and functions. The wing antenna comprises a wing framework, a wing cover and a control and signal processing system. The wing cover sequentially comprises, from top to bottom, an upper panel, an upper honeycomb/foaming layer, a radio frequency function layer, a lower honeycomb/foaming layer and a lower panel. Optical fiber is laid on the lower panel. Bragg gratings are arranged at intervals on each stick of optical fiber. The radio frequency function layer comprises a radio frequency circuit layer, a wave control circuit layer and a packaging framework. A liquid cooling passage is manufactured in the radio frequency function layer. The radio frequency circuit layer comprises an antenna array face composed of a plurality of antenna sub-arrays arrayed in a distribution arraying mode. Each antenna sub-array is composed of a plurality of micro-strip radiation units. The wing antenna has the advantages of reducing the weight of a plane body, improving the pneumatic performance of an aircraft, being good in heat dissipating, being capable of monitoring the deformation and the strength of the wing structure in real time and automatically compensating the influence of structure vibration and deformation on electrical performance, and ensuring the electromagnetic performance stability of the antenna in severe environments.

Description

technical field [0001] The invention relates to a wing antenna, in particular to a structure-function integrated wing antenna, which belongs to the technical field of aircraft antennas. Background technique [0002] The structure-function integrated wing antenna refers to the embedding of the radio frequency functional parts of the integrated microstrip antenna array into the wing structure of the aircraft. The highly integrated skin antenna manufactured by the integrated compound molding process can be used as a weapon platform The mechanical load-bearing functional parts of the structure can also be used as electromagnetic functional parts for sending and receiving wireless electromagnetic waves. Compared with traditional antennas, the structure-function integrated wing antenna has the characteristics of high integration of structure and circuit. It can be applied to future aircraft such as variant aircraft, unmanned aerial vehicles, airship early warning aircraft, etc. I...

Problems solved by technology

[0008] 1. In the technical solutions disclosed in the existing documents, only the method of integrating the microstrip antenna array into the wing structure is given. However, the layout method of the antenna in the wing structure, the radio frequency signal connection method and the production method are not described. method

[0009] 2. Since the microstrip antenna is highly integrated into the wing structure, when the antenna is working, the radio frequency device will heat up, resulting in reduced radiation performance of the antenna, or even complete failure
