Problems solved by technology

Most of the antennas protruding from the outside of the fuselage are knife antennas or whip antennas, but traditional antennas installed inside or outside the aircraft will seriously affect the aerodynamic characteristics of the aircraft, and will also increase the radar cross section of the aircraft. very deadly

Abstract

The invention discloses a high-gain conformal antenna suitable for the head of a high-speed aircraft, a microstrip patch unit comprises a dielectric substrate, a radiator and a grounding plate, the grounding plate is connected with a metal thin layer at the bottom of the dielectric substrate and is located below the dielectric substrate, and the radiator is embedded in the upper part of the dielectric substrate. A 8 * 8 array antenna which is attached to the surface of an aircraft carrier and has the same shape with the head of an aircraft is formed through the microstrip patch unit array, and meanwhile, one-to-64 feed is realized by adopting a T-shaped power division structure, so that the space required by array arrangement is reduced, the coupling degree is reduced, the defect that the inherent beam scanning performance of a planar array is quickly reduced along with the increase of a scanning angle is overcome, a wider wave beam coverage range is realized, and the antenna has the advantages of simple feed and high gain.

Description

Technical field [0001] The present invention relates to the field of antenna technology, and more particularly to a high gain common antenna suitable for use in the high speed aircraft head. Background technique [0002] In order to meet the needs of communication, there are many different antennas on the military aircraft, and most of them are highlighted outside the fuselage. Highlight the antenna outside the fuselage antenna or a whip antenna, but the traditional antenna mounted inside the aircraft, will seriously affect the aerodynamic characteristics of the aircraft, and increase the radar scatter cross section of the aircraft, for the stealth aircraft Very deadly. [0003] Therefore, the application of common antennas in modern aircraft becomes a hot problem, because it can meet the new functional requirements of the aircraft, after using a common antenna, the antenna and the antenna cover will integrate, no additional antenna cover to protect the antenna. It is possible to...
