Splicable antenna module for wide area coverage

Abstract

The invention relates to a splicable antenna module for wide area coverage. The module comprises a radiation unit, a radio frequency connector, an N-polygon splicing substrate, an angle adjustable splicing connector, a heat dissipation module and a TR module, wherein the angle adjustable splicing connector comprises a splicing connector 1, a splicing connector 2 and a rotation locking mechanism. The invention provides a splicable mechanical, electric and thermal integrated design antenna module. The N-polygon splicing substrate is a mounting fixed substrate of the radiation unit, the angle adjustable splicing connector and the heat dissipation module and also is a splicing configuration basis of splicing the antenna module into a plane or a conformal shape. By adjusting the angle a of theangle adjustable splicing connector, the splicing angle requirement of the array antenna can be achieved. The quick splicing of a frameless plane and a conformal array antenna and the angle adjustmentof the conformal antenna are achieved. The size of the antenna module can be adjusted according to needs, thus the overall size of the spliced array antenna is adjustable, and the antenna module is versatile.

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 ...

AI Technical Summary

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.
