Abstract

The invention provides a wing skeleton antenna, and relates to the technical field of antennas. The wing skeleton antenna comprises: a plurality of frame modules; the frame module comprises a metal framework, a high-strength medium framework and a feeder line; the adjacent metal frameworks are mechanically connected through the high-strength medium frameworks, and on the basis that the structural strength and weight of the frame module and the aerodynamic shape of the wing framework are guaranteed, electrical isolation between the metal frameworks is achieved. The metal framework is connected with a transmitting source and/or a receiver through a feeder line to realize an antenna function of the framework module; the wing skeleton realizes the antenna load with electromagnetic signal emission and structure functions through the frame module instead of moving the antenna load from the fuselage to the wing, so that the functionality of the wing skeleton can be effectively improved, and the total electronic load weight and the total occupied space of the aircraft are reduced.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a wing frame antenna. Background technique [0002] With the rapid development of aircraft technology, reducing the weight of the electronic load on the aircraft and improving the flight time of the aircraft have increasingly become the focus of scholars and manufacturers in colleges and universities. The wing is an important part of the aircraft. Although the size of the wing is large in the unfolding direction, the internal space of the wing is small, and the metal wing skeleton structure is densely covered to ensure the structural strength required for the flight function. Underutilized in aircraft, the wings only provide aerodynamic flight. [0003] In recent years, various wing skin conformal antennas have been proposed. Such antennas typically have a low profile and can be conformally designed to fit the contour of the wing skin. The wings equipped with such wing skin a...
