A splicable antenna module for wide area coverage

Abstract

The invention relates to a splicable antenna module for wide-area coverage, including a radiation unit, a radio frequency connector, an N-gon splicing substrate, an angle-adjustable splicing connector, a heat dissipation module, and a TR module, wherein the angle-adjustable splicing connector Including the splicing connector 1, the splicing connector 2 and the rotation locking mechanism. The present invention proposes a splicable antenna module with integrated electromechanical design. The N-gon splicing substrate is not only the installation and fixing substrate of the radiation unit, the angle-adjustable splicing connector and the heat dissipation module, but also the splicing of the antenna module into a plane or conformal shape. Based on the splicing configuration of the array antenna, by adjusting the angle a of the angle-adjustable splicing connector, the splicing angle requirement of the array antenna can be realized. The invention realizes the rapid splicing of the skeletonless plane and the conformal array antenna, and the function of adjusting the angle of the conformal antenna. The size of the antenna module can be adjusted according to requirements, so that the size of the whole array antenna after splicing can be adjusted and has versatility.

Description

technical field [0001] The invention relates to the field of antenna structures for wide-area coverage, in particular to a spliceable antenna for wide-area coverage. Background technique [0002] The present invention derives from curved surface conformal antennas. The curved surface array antenna conforms each discrete unit on a curved surface structure, and the units at different positions have different orientations, which can effectively ensure the wide-angle coverage of the beam, and the gain change is relatively balanced in the entire scanning area. [0003] According to mission requirements, when the antenna beam coverage is greater than ±75°, it has low elevation angle communication capability. For a planar array, when the scanning range is greater than ±45°, the beam pointing will have a large deviation, and the larger the scanning angle, the greater the pointing deviation will be. And when the scanning angle is greater than ±60°, the beam gain will drop by 6-7dB ...

Problems solved by technology

[0005] The traditional conformal array antenna structure is generally processed by an integrated skeleton, which is complicated to process, difficult to conform to, and high in cost. In addition, the active module and thermal control components need to adapt to the design and assembly of the antenna skeleton, and the integration of the whole machine is low and the flexibility is poor.
