Problems solved by technology

However, since the airborne antenna requires a wide bandwidth, and the large gap between high and low frequency wavelengths is likely to cause distortion in the horizontal pattern of high frequency gain, this has become another major difficulty in the design of airborne antennas

Embodiment Construction

[0028] The present invention is described below based on examples, but the present invention is not limited to these examples. In the following detailed description of the invention, some specific details are set forth in detail. The present invention can be fully understood by those skilled in the art without the description of these detailed parts. In order to avoid obscuring the essence of the present invention, well-known methods, procedures, and flow charts are not described in detail. Additionally, the drawings are not necessarily drawn to scale.

[0029] figure 1 is a schematic diagram of an exemplary aircraft. As shown in the figure, the aircraft 10 includes a fuselage 12 , wings 11 , a vertical stabilizer 13 and a horizontal stabilizer 14 . The airborne antenna can be arranged inside or integrated with the surface of at least one of the wing 11 , the vertical tail 13 and the horizontal tail 14 . When designing an aircraft, the airborne antenna and the components ...

Abstract

The invention provides an airborne antenna and an aircraft. The airborne antenna comprises a dielectric substrate and two or more radiation sections arranged on the surface of the dielectric substrate, the two or more radiation sections are connected through an impedance matching line, each radiation section is of an axial symmetry structure, and the symmetry axes of different radiation sections have the same direction. By adopting the segmented design of the radiator, the problem of horizontal pattern distortion of the antenna at a high frequency band is improved, and the gain of the antenna at the high frequency band is considered on the basis of satisfying the gain of the antenna at a low frequency band.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an airborne antenna and an aircraft. Background technique [0002] With the development of wireless communication technology, antennas, as an important device for wireless communication, are being used more and more widely, and various types of antennas have emerged as the times require. Among them, the airborne antenna is used to send and receive signals for various systems installed on the aircraft, and its importance is self-evident. However, since the airborne antenna requires a wide bandwidth, and the large gap between high and low frequency wavelengths is likely to cause distortion in the horizontal pattern of high frequency gain, this has become another major difficulty in the design of airborne antennas. Contents of the invention [0003] In view of this, the present invention provides an airborne antenna to solve the above problems. [0004] Accordi...
