[0016] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are:

[0017] For a short-wave two-way antenna device provided by an embodiment of the present invention, since a plurality of oscillator assemblies are evenly spaced along the circumferential direction of the support tower and are located at the top of the support tower, each oscillator assembly can independently receive and transmit electromagnetic signals, and can receive and transmit electromagnetic signals in all directions of 360°.

Detailed Embodiments

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Figure 1 FIG. is a schematic structural diagram of a shortwave bi-directional antenna device provided by an embodiment of the present invention, Figure 2 FIG. is a top view of a shortwave bi-directional antenna device provided by an embodiment of the present invention. As shown in combination with Figure 1 and Figure 2 shown, the antenna device includes a support tower 1 and a plurality of oscillator assemblies 2.

[0029] The plurality of oscillator assemblies 2 are arranged at equal intervals along the circumferential direction of the support tower 1 and are located at the top of the support tower 1.

[0030] Figure 3 FIG. is a schematic structural diagram of an oscillator assembly provided by an embodiment of the present invention. As shown in Figure 3, for any one oscillator assembly 2, the oscillator assembly 2 includes a main rod 21 made of a metal structure, a plurality of support rods 22, a plurality of first diagonal rods 23 and a plurality of second diagonal rods 24. The plurality of support rods 22 are arranged at intervals along the circumferential direction of the main rod 21, and one end of each support rod 22 is connected to the middle part of the main rod 21. The two ends of each first diagonal rod 23 are respectively connected to the other ends of two adjacent support rods 22. One end of the main rod 21 is insulated and installed on the outer peripheral wall of the support tower 1, and the main rod 21 extends along the radial direction of the support tower 1. One end of each second diagonal rod 24 is connected to the main rod 21, and the other end of each second diagonal rod 24 is connected to the corresponding support rod 22 or at least one first diagonal rod 23, so that the plurality of first diagonal rods 23 and the plurality of second diagonal rods 24 form a double pyramid structure.

[0031] For a short-wave bidirectional antenna device provided by an embodiment of the present invention, since a plurality of oscillator assemblies 2 are arranged at uniform intervals along the circumferential direction of the support tower 1 and are located at the top of the support tower 1, each oscillator assembly 2 can independently receive and transmit electromagnetic signals, and can receive and transmit electromagnetic signals in all directions of 360°.

[0032] Furthermore, the plurality of support rods 22 are arranged at intervals along the circumferential direction of the main rod 21, and one end of each support rod 22 is connected to the middle part of the main rod 21. The two ends of each first diagonal rod 23 are respectively connected to the other ends of two adjacent support rods 22. One end of the main rod 21 is insulated and installed on the outer peripheral wall of the support tower 1, and the main rod 21 extends along the radial direction of the support tower 1. One end of each second diagonal rod 24 is connected to the main rod 21, and the other end of each second diagonal rod 24 is connected to the corresponding support rod 22 or at least one first diagonal rod 23, so that the plurality of first diagonal rods 23 and the plurality of second diagonal rods 24 form a double pyramid structure. Thus, the oscillator can be divided into the main rod 21, the plurality of support rods 22, the plurality of first diagonal rods 23 and the plurality of second diagonal rods 24, forming a fold in three-dimensional space to reduce the horizontal size, and at the same time can receive and transmit horizontally polarized electromagnetic signals, and maintain the effective electrical length of the oscillator of the antenna device.

[0033] That is to say, a short-wave bidirectional antenna device provided by the present invention can not only receive and transmit horizontally polarized electromagnetic signals in all directions of 360°, but also maintain the effective electrical length of the oscillator of the antenna device.

[0034] In this embodiment, the number of support rods 4 can be 4, and the 4 support rods are arranged in a cross shape. The main rod 21 is vertically connected to the 4 support rods. The number of first diagonal rods 23 can be 4, and the number of second diagonal rods can be 8. The 4 first diagonal rods 23 and the 8 second diagonal rods 24 form a double pyramid structure. Among them, the main rod 21 and the 4 support rods are the internal support structures of the double pyramid structure, ensuring that the structure of each oscillator assembly 2 is more stable.

[0035] Continue to refer to Figure 3, the oscillator assembly 2 further includes a plurality of insulating support rods 25, and the plurality of insulating support rods 25 are symmetrically arranged along the main rod 21. Both ends of each insulating support rod 25 are respectively connected to one end of at least one second diagonal rod 24 and the outer peripheral wall of the support tower 1.

[0036] In the above embodiment, the insulating support rods 25 play a further supporting role for the entire oscillator assembly 2 (increasing the number of connection points between the oscillator assembly 2 and the support tower 1), thereby ensuring the stability of the installation of the oscillator assembly 2 on the support tower 1.

[0037] Figure 4 is a schematic structural diagram of the support tower provided by an embodiment of the present invention. In combination with Figure 1 and Figure 4 as shown, there are a plurality of hanging ears 11 on the outer peripheral wall of the support tower 1. The plurality of hanging ears 11 are arranged at intervals along the circumferential direction of the support tower 1. One end of each insulating support rod 25 is fixedly installed on the corresponding hanging ear 11, so as to realize the connection between the insulating support rod 25 and the support tower 1 through the hanging ear 11.

[0038] In one implementation manner of the present invention, the axial direction of each insulating support rod 25 is coaxial with the axial direction of one second diagonal rod 24, so as to make the supporting force of the insulating support rod 25 on the second diagonal rod 24 coaxial with the second diagonal rod 24, and the supporting effect is better.

[0039] In this embodiment, the outer peripheral wall of the support tower 1 has a plurality of insulating seats 12. The plurality of insulating seats 12 are evenly arranged at intervals along the circumferential direction of the support tower 1. One end of each main rod 21 is installed on the corresponding insulating seat 12, so that through the insulating seat 12, it is not only convenient to fix the main rod 21, but also the insulation between the main rod 21 and the support tower 1 can be realized.

[0040] Exemplarily, the insulating seat 12 is of a U-shaped structure. The two side plates of the insulating seat 12 are respectively fixed on the support tower 1, which can increase the connection strength between the insulating seat 12 and the support tower 1. One end of the main rod 21 is fixedly installed on the connecting plate of the insulating seat 12 (the two side plates are connected by the connecting plate).

[0041] Continue to refer to Figure 1 , the support tower 1 includes a first support section 13, a connection section 14 and a second support section 15 that are coaxially connected in sequence. A plurality of insulating seats 12 are fixedly installed on the outer peripheral wall of the connection section 14, and the connection section 14 is connected to the first support section 13 or the second support section 15 through a flange.

[0042] In the above embodiment, by setting the support tower 1 as the first support section 13, the connection section 14 and the second support section 15, it is convenient to install the insulating seats 12 on the connection section 14.

[0043] Exemplarily, before arranging the support tower 1, a plurality of insulating seats 12 are installed on the connecting section 14 in advance, and finally the connecting section 14 is connected to the first support section 13 and the second support section 15.

[0044] To increase the connection strength of each rod in the oscillator assembly 2 and improve the assembly efficiency, at least two of the main rod 21, a plurality of support rods 22, a plurality of first diagonal rods 23, and a plurality of second diagonal rods 24 are connected by a conductive joint 26.

[0045] Exemplarily, the number of conductive joints 26 is 7. Among them, 6 are respectively located at the corners of the double pyramid, and 1 is located at the center of the double pyramid (connecting the main rod 21 and a plurality of support rods 22).

[0046] Exemplarily, the conductive joint 26 has a plurality of ear plates arranged circumferentially, and the installation of each rod is realized through the ear plates.

[0047] In this embodiment, the support tower 1 is provided with a plurality of ladders 16, and the plurality of ladders 16 extend along the length direction of the support tower 1, so as to facilitate the maintenance and installation of the oscillator assembly 2.

[0048] Exemplarily, the number of oscillator assemblies 2 is 4 - 8, preferably 4, and two adjacent oscillator assemblies 2 are arranged at 90°.

[0049] It should be noted that the beam circumferential coverage of a single oscillator assembly 2 is ≥100°, and the maximum radiation direction is achieved by 4 oscillator assemblies 2 to provide an omnidirectional beam coverage with high elevation angle and horizontal polarization.

[0050] Exemplarily, the support tower 1 can be made of steel structure, and the support tower 1 is a self-supporting tower or a guyed tower.

[0051] In addition, the bottom of the support tower 1 has a notch, and a signal transceiver 17 is provided inside the support tower 1. The signal transceiver 17 is opposite to the notch, which is convenient for installation and maintenance. The signal transceiver 17 and each oscillator assembly 2 are electrically connected through cables, so as to realize signal transmission and reception.

[0052] Figure 5 is the signal radiation pattern of a short-wave bi-directional antenna device provided by an embodiment of the present invention. As Figure 5 shown, through electromagnetic simulation software simulation calculation, in the angle range of -60° to 60° of beam coverage, the normalized radiation energy intensity is high and the communication effect is good; it has near-vertical incident beam and medium-high elevation angle beam coverage, which can meet the short-wave communication requirements for short distance and medium-long distance. Designing the antenna device into this double pyramid structure, the curve is full and smooth in the medium-high elevation angle direction, which can ensure short-distance communication.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
