Description

Technical Field

[0001] The utility model relates to the technical field of horn antennas, in particular to a double-ridge structure ultra-wideband horn antenna. Background Technique

[0002] A horn antenna is a surface antenna, a microwave antenna with a circular or rectangular cross-section that gradually expands at the end of a waveguide, and is one of the most widely used types of microwave antennas. Its radiation field is determined by the aperture size of the horn and the propagation mode. Among them, the influence of the horn wall on radiation can be calculated using the principle of geometric diffraction. If the length of the horn remains unchanged, the aperture size and the quadratic phase difference will increase as the flare angle of the horn increases, but the gain will not change with the aperture size. If it is necessary to expand the frequency band of the horn, it is necessary to reduce the reflection at the neck and aperture of the horn; the reflection will decrease as the aperture size increases.

[0003] However, the existing double-ridge structure ultra-wideband horn antennas are often relatively simple to fix. During use, the double-ridge structure ultra-wideband horn antennas are often not convenient to rotate, or are prone to damage when rotating, which greatly affects the use of staff. For the above problems, a double-ridge structure ultra-wideband horn antenna is disclosed in Patent CN202222064944.8, including a horn antenna mechanism. A support mechanism is arranged on one side of the horn antenna mechanism. The support mechanism includes a clamping frame and a support column. An inner positioning disk is arranged on the upper side of the support column, a rotating motor is arranged on the upper side of the inner positioning disk, and a plurality of support feet are arranged on the outer side of the support column. When the rotating motor is turned on in the utility model, the connection card slot can drive the binding frame to rotate, the rotation of the binding frame drives the horn antenna mechanism to rotate, the rotation of the horn antenna mechanism drives the clamping frame to rotate, and the rotation of the clamping frame makes the limit post move circumferentially between the inner positioning disk and the outer positioning disk, playing a limiting role, greatly enhancing the support strength of the support column for the horn antenna mechanism. The outer positioning disk can be supported by a plurality of support feet, and it is convenient for staff to fix through the support column.

[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution: a dual-ridge structure ultra-wideband horn antenna, including a dual-ridge horn antenna 1, a connecting plate 2 is welded to the side of the dual-ridge horn antenna 1, the connecting plates 2 are symmetrically arranged with respect to the dual-ridge horn antenna 1, a single-headed threaded pin shaft 3 is fixed by a nut between the two connecting plates 2, there are two single-headed threaded pin shafts 3, a connector 4 is fixed by screws between the two single-headed threaded pin shafts 3, a rotating seat 5 is fixed at the end of the connector 4 away from the single-headed threaded pin shaft 3, a fixed plate 6 and an installation platform 7 are respectively arranged on both sides of the rotating seat 5, a plurality of support rods 8 are fixed between the fixed plate 6 and the installation platform 7, a rotating shaft 9 is rotatably connected between the fixed plate 6 and the installation platform 7, the rotating shaft 9 is fixedly connected to the rotating seat 5, a motor 10 is connected to the end of the rotating shaft 9 facing the fixed plate 6, the motor 10 is fixed on the fixed plate 6, and an angle adjusting member is also connected to the side of the rotating shaft 9.

[0030] Among them, the height of the top of the set support rod 8 from the surface of the installation platform 7 is greater than the overall height of the dual-ridge horn antenna 1, so as to facilitate the 360° rotation of the horn antenna around the center of the installation platform 7 and avoid interference of the support rod 8.

[0031] Furthermore, after the motor 10 is turned on, the motor 10 can drive the rotating shaft 9 to rotate. Then, with the rotation of the rotating shaft 9, the rotating seat 5 can be driven to rotate. Within the rotation plane of the rotating seat 5, the dual-ridge horn antenna 1 can follow the rotation, thereby realizing the rotation adjustment of the dual-ridge horn antenna 1.

[0032] At the same time, a cross bar 11 is fixed inside the rotating seat 5, and the outside of the cross bar 11 is elastically rotatably connected to the connector 4.

[0033] Specifically, the angle adjustment member includes a connecting rod 12 fixed to the side surface of the rotating shaft 9. A sliding seat 13 is fixed to the end of the connecting rod 12 away from the rotating shaft 9. The sliding seat 13 is rotatably connected along the circumferential direction of the fixing plate 6. A groove 14 is provided at the end of the sliding seat 13 facing the fixing plate 6. A piston rod 15 is slidably connected inside the sliding seat 13.

By inserting the single-headed threaded pin shafts 3 into the inside of the connecting plate 2 and fixing them with nuts, and at the same time installing the screws between the two single-headed threaded pin shafts 3 on both sides of the connecting head 4. After the horn antennas are installed, the set motor 10 can be opened to drive it to rotate along the circumferential direction of the fixing plate 6. At the same time, when the cylinder 16 is opened, the up-and-down swing of the connecting head 4 can be driven to perform angle adjustment.
