Description

Technical Field

[0001] The utility model relates to the technical field of radar, and specifically relates to a new type of antenna array system with high efficiency and stability. Background Art

[0002] An antenna array system is essentially a radiation system, which is used to enhance the directivity of an antenna or obtain the required directional characteristics.

[0003] In practical applications, in order to adapt to the different detection ranges of different radars, it is necessary to specifically set the area of the radar antenna array. Specifically, in order to facilitate the adaptive adjustment of the antenna array area, the antenna array system is set to be composed of several sub-arrays spliced together.

[0004] However, the inventor found that for the existing antenna array system, on the one hand, the sub-arrays spliced in the prior art are generally large-sized integral structures composed of multiple row feeds; this results in great difficulty in disassembling after the array is assembled, and it can only be used fixedly; it cannot be used in scenarios with small installation spaces such as on an aircraft. At the same time, the row feeds that make up the sub-array can generally reach several meters in length, and due to manufacturing process limitations, it is impossible to effectively ensure the straightness and flatness of the row feeds in the length direction, resulting in the gap between each sub-array and even between the row feeds in any sub-array exceeding the minimum allowable value; this may affect the electrical continuity of the entire array system and have an adverse impact on the effectiveness of the final monitoring. On the other hand, only grounding strips are relied on to fix between each sub-array, which also makes it impossible to ensure the connection reliability of the entire array.

"Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0039] The following technical defects exist when splicing existing antenna arrays: (1) In the prior art, the sub-arrays for splicing are generally relatively large integral structures composed of multiple row feeds; this results in a large difficulty in disassembling the array after assembly, and it can only be used fixedly; it cannot be used in scenarios with limited installation space such as on an aircraft. (2) The row feeds that make up the sub-arrays are generally several meters long, and due to manufacturing process limitations, it is impossible to effectively ensure the straightness and flatness of the row feeds in the length direction, resulting in inevitable excessive gaps between the sub-arrays and even between the row feeds of any sub-array; this may affect the electrical continuity of the overall array and have an adverse impact on the effectiveness of the final monitoring. (3) The sub-arrays are only fixed by grounding strips, which also makes it impossible to ensure the connection reliability of the entire array. Based on this, this embodiment provides a highly efficient and stable new antenna array system to simultaneously improve the above defects.

[0040] The following further specifically introduces the highly efficient and stable new antenna array system disclosed by the present utility model in conjunction with the embodiments shown in the accompanying drawings.

[0041] Combined with Figures 1-6As shown, the array system includes: a plurality of power dividers 1, a plurality of antenna element modules 2, and a plurality of grounding bars 3. The power divider 1 has a rectangular structure, with its length ranging from 80 mm to 120 mm and its width ranging from 50 to 90 mm.

[0042] For the convenience of description, in the power divider 1, the first surface and the second surface are defined as a pair of opposite surfaces, the third surface and the fourth surface are defined as a pair of opposite surfaces, and the fifth surface and the sixth surface are defined as a pair of opposite surfaces.

[0049] Preferably, a plurality of second mounting holes are provided on the grounding bar 3, and a plurality of third mounting holes are provided at the bottom of the third special-shaped groove 15. The second mounting holes and the third mounting holes are in one-to-one correspondence and adaptation, so that the corresponding fixing members pass through the correspondingly arranged second mounting holes and third mounting holes, which can further improve the installation reliability of the grounding bar 3. Specifically, the corresponding fixing members are screws. The grounding bar 3 in this embodiment also functions to ensure electrical continuity. Based on this, the grounding bar 3 is made of aluminum.

Specifically, a plurality of fourth special-shaped grooves 41 are provided on the first end cap 4, and the fourth special-shaped grooves 41 are in one-to-one correspondence and adaptation with the second T-shaped protrusions 13. At the same time, a plurality of third T-shaped protrusions 51 are provided on the second end cap 5, and the third T-shaped protrusions 51 are in one-to-one correspondence and adaptation with the second special-shaped grooves 14.

[0052] Furthermore, in order to improve the fixing reliability between the first end cap 4 or the second end cap 5 and the power divider 1, a plurality of fourth mounting holes are provided on the first end cap 4, a plurality of fifth mounting holes are provided on the second end cap 5, a plurality of sixth mounting holes are provided on the third surface, and a plurality of seventh mounting holes are provided on the fourth surface. At this time, the fourth mounting holes and the sixth mounting holes are arranged in one-to-one correspondence for the corresponding fixing members to pass through to realize the fastening of the first end cap 4 and the power divider 1, and the fifth mounting holes and the seventh mounting holes are arranged in one-to-one correspondence for the corresponding fixing members to pass through to realize the fastening of the second end cap 5 and the power divider 1. In this embodiment, the corresponding fixing members are specifically screws.

[0053] To facilitate the support and fixation of the array system formed after splicing each row of feeds, a support frame is also provided. Correspondingly, at this time, both the first end cover 4 and the second end cover 5 include a horizontal plate and a vertical plate that are perpendicularly fixed to each other. Specifically, a number of fourth special-shaped grooves 41 are provided on the horizontal plate of the first end cover 4, and the vertical plate of the first end cover 4 is fixed to the support frame. A number of third T-shaped protrusions 51 are provided on the horizontal plate of the second end cover 5, and the vertical plate of the second end cover 5 is fixed to the support frame. At this time, the fixation and support of the array system can be realized through the fixation between the first end cover 4 and the fifth end cover 5 and the support frame.
