Embodiment Construction

[0029] Below in conjunction with embodiment the present invention is described in further detail:

[0030] A miniaturized anti-jamming antenna array, comprising a conical missile-borne structure 1, a circular platform 1-1 in the middle of the conical missile-borne structure 1 is an array area for active antenna elements, and the radius of the upper surface of the circular platform 1-1 is 41.3mm, the radius of the lower table is 54.5mm, and the height between the upper table and the lower table of the circular table 1-1 is 55mm. In order to reduce the space range required for the arrangement of the active antenna elements under this structure, the active antenna elements are installed on the conical missile-borne structure in the form of "3+1" and connected with the conical missile-borne structure. The surface conformal design effectively reduces the space range required for the array of active antenna arrays under this structure, and solves or partially solves the problem that...

Abstract

The invention discloses a miniaturized anti-jamming antenna array, which includes a conical missile-borne structure, and the round platform in the middle of the conical missile-borne structure is the array area of ​​active antenna arrays. The active antenna array is integrated with antenna radiation Multifunctional devices including body, antenna radiation patch, antenna feeding network board, low noise amplifier PCB board, shielding cover, radome and metal pressing block realize the reduction of the physical size of the active antenna element while increasing the integration The antenna performance is improved; the active antenna array is installed on the conical missile-borne structure in the form of "3+1" and is designed conformally with the surface of the conical missile-borne structure, which effectively reduces the impact of the structure. The space range required for the active antenna array array solves or partially solves the problem that the anti-jamming antenna array under the conical missile-loaded structure must be adaptively selected due to carrier occlusion. Research on the array layout method in similar application scenarios has far-reaching significance.

Description

technical field [0001] The invention relates to the technical field of antenna arrays, in particular to a miniaturized anti-jamming antenna array. Background technique [0002] With the continuous improvement of the domestic Beidou satellite navigation system and the maturity of satellite application technology, the field of antenna array technology is also constantly innovating. Among them, the anti-jamming antenna array technology is more and more widely used, and the application scenarios are becoming more and more diversified, complex and miniaturized, which brings great challenges to the realization of the performance of the anti-jamming array antenna. As the speed increases, the influence of the antenna single array on the performance of the anti-jamming antenna is gradually deepened. Especially for the anti-interference requirements in various narrow spaces or unconventional structures, the requirements for the performance of the antenna single array and the form of ...
