Embodiment Construction

[0028] The present invention is a split structure, including a central lobe 1 and a plurality of fan-shaped petals 2 evenly distributed around the central lobe 1; its central lobe 1 includes a central reflective panel 6 and a central base fixedly connected to the back of the central reflective panel 6 8. A plurality of long reinforcing ribs 9 and a plurality of short reinforcing ribs 10; its fan-shaped flap 2 includes a fan-shaped reflective panel 7 and a reinforcing rib 14 fixedly connected to the back of the fan-shaped reflective panel 7; between the central flap 1 and the fan-shaped flap 2 and multiple The fan-shaped lobes 2 are all connected in a detachable manner; the central reflector panel 6 and multiple fan-shaped reflector panels 7 together form the reflector panel of the antenna reflector.

[0029] Both the central reflective panel 6 and the fan-shaped reflective panel 7 are sandwich structures, including aluminum honeycomb panels and carbon fiber inner and outer skin...

Abstract

The invention discloses a split type high-accuracy antenna reflector adopting an all-composite material, and relates to the fields of wireless detection, satellite communication, electronic measurement and control, electronic interference and the like. The antenna reflector adopts a split structure and comprises a center section and a plurality of fan-shaped sections uniformly distributed around the center section, wherein the center section comprises a center reflection panel, a center base fixedly connected to the back of the center reflection panel, a plurality of long reinforcing ribs and a plurality of short reinforcing ribs; the fan-shaped sections comprise fan-shaped reflection panels and reinforcing ribs fixedly connected to the backs of the fan-shaped reflection panels; the center section and the fan-shaped sections are detachably connected, and the plurality of fan-shaped sections are detachably connected; and the center reflection panel and the plurality of fan-shaped reflection panels jointly form a reflection panel of the antenna reflector. According to the split type high-accuracy antenna reflector adopting the all-composite material, the split mode of a large-diameter antenna is optimized, meanwhile, the reflection panel and a reinforcing back frame are integrally designed, the structure is stable, and transportation, erection and operation of the antenna reflector are facilitated.

Description

technical field [0001] The invention relates to an antenna reflector in the fields of wireless detection, satellite communication, electronic measurement and control, electronic interference, etc., and is especially suitable for antenna reflectors that require light weight, quick disassembly and assembly, and high working frequency band. Background technique [0002] With the continuous development of communication, measurement and control and other electronic technologies, long-range wireless detection, satellite communication, electronic measurement and control and other fields not only widely use parabolic antennas, but also have higher and higher requirements for the mobility, quick response and working frequency band of antennas. For large-aperture parabolic antennas, in order to meet the performance requirements of road transportation, split assembly is required. At present, the traditional parabolic antenna basically adopts the fan-shaped equal-section cutting method ...
