Description

The utility model relates to antenna technology and is intended to build antenna arrays, used, in particular, in radar systems and communication systems.

The well-known "Lattice of radiating elements" [RU 2140691 published 10.27.1999 IPC H01Q 21/00], in which a linear array of rectangular waveguide emitters, intended for use as a module in a two-dimensional phased antenna array, in which each radiating element contains a waveguide, and emitting the elements are installed mainly in parallel, on the back side, each radiating element is in communication with a radiation energy source, and a diaphragm is installed at the outer ends of the radiating elements. Each radiating element has, at least in a certain section along the length, a part of a U-shaped cross section that is fixed to the wall common to all radiating elements with the bases of the side walls.

Known modular waveguide-horn emitter antenna "Modular waveguide feed horn" [US 2009/0066598 A1 published 12.03.2009, IPC H01Q 13/02]. The modular waveguide-horn radiator of the antenna is designed in such a way that it includes a node with a plate of waveguides. The modular waveguide-horn radiator of the antenna also includes a horn radiator section containing at least one horn radiator. The horn emitters section is made separately with the possibility of attaching waveguides to the plate. Many horn emitters are paired.

The disadvantage of these solutions is their low reliability.

The closest in technical essence is the “Panel of waveguide-horn emitters” [RU 175123, published 11/21/2017, IPC H01Q 13/02], containing a line of waveguide-horn emitters, a front metal plate and a rear metal plate, with rectangular windows made in them located opposite each other. The front metal plate and the rear metal plate are rigidly connected to each other by lines of waveguide-horn emitters installed between them, in addition, the front metal plate is made with a set of grooves, and the line of waveguide-horn emitters with protrusions for connecting them.

Under the effect of overloads on the panel of waveguide-horn emitters, the main load falls on the connection of the lines of waveguide-horn emitters and the back plate, for example, by soldering, which reduces the reliability of the interface with an external device.

The technical result of the proposed radiating module of the antenna array is to increase the reliability and quality of the interface with an external device.

The essence of the proposed radiating module of the antenna array is that it contains a metal plate with rectangular windows and two lines of waveguide-horn emitters installed in the window of the plate.

New in the proposed technical solution is that the line of waveguide-horn emitters are parallel to each other and interconnected by stiffeners. The outer side walls of the lines of waveguide-horn emitters are made with flanges in the lower part, and overlays are installed along the inner side walls in their lower part, and flanges with overlays form contact surfaces and connections with external devices. The line of waveguide-horn emitters is made of two curved metal plates, one of which is flanged, and step partitions arranged in such a way that step partitions, together with two plates installed on both sides of the step partitions, form waveguide-horn emitters, rigidly connecting the assembly of the line of waveguide-horn emitters. Flanges are made L-shaped. On flanges corners are fixed for reinforcement.

In FIG. 1 shows a General view of the radiating module of the antenna array.

In FIG. 2 shows a top view of the radiating module of the antenna array.

In FIG. 3 shows a General view of the line of waveguide-horn emitters.

The radiating module of the antenna array consists of a metal plate (1), in which windows (2) and two lines of waveguide-horn emitters (3) are made. Rulers of waveguide-horn emitters (3) are located parallel to each other and are installed in the windows (2) of the plate (1). In addition, the line of waveguide-horn emitters (3) are connected by stiffeners (7). The outer side walls of the lines of waveguide-horn emitters (3) are made in the form of curved plates (9) with flanges (8), for example, L-shaped. Along the inner side walls made in the form of curved plates (5), pads (6) are installed in their lower part. Flanges (8) and pads (6) form contact surfaces and connections with external devices. To strengthen the structure at the joints with external devices, flanges (4) can be installed on flanges (8).

The line of waveguide-horn emitters (3) is made of a set of stepped partitions (10) and two curved metal plates (5), (9) installed on both sides of them, forming waveguide-horn emitters (11). The plate (9) is flanged (8).

The radiating module of the antenna array is designed to build antenna arrays. For this, the emitting module is mounted on an external device, for example a phasing device. The radiating module of the antenna array is combined with an external device, and flanges (8) with overlays (6) form the contact and connection surfaces, providing high-quality electrical connection to the waveguide-horn emitters (11) and the external device. The fastening of the radiating module of the antenna array by flanges (8) and overlays (6) of the lines of waveguide-horn emitters (3) in conjunction with their connection by stiffeners (7) increases the reliability of the interface with external devices. Corners (4) mounted on flanges (8) reinforce the structure at the attachment points.

The radiating module of the antenna array operates as follows. An external device, such as a phasing device, transmits a microwave signal to waveguide-horn emitters (11) that radiate it into space. In this case, the distribution of the electromagnetic field is formed over the opening of the radiating module of the antenna array.

The radiating module of the antenna array can be made of alloy AMts by soldering. The lines of waveguide-horn emitters (3) are connected by stiffeners (7), and then the lines of waveguide-horn emitters (3) with corners fixed on the flanges (8) (4) are installed in the windows (2) of the plate (1), and along the inner side walls made in the form of plates (5), a line of waveguide-horn emitters (3) install the lining (6) and then solder the structure.

Thus, the use of flanging and overlays on the walls of the lines of waveguide-horn emitters, together with their connection by stiffeners, can improve the reliability and quality of the interface with an external device.
