Embodiment Construction

[0027] The present invention is a split-lobe structure, which includes a central lobe 1 and a plurality of fan-shaped lobes 2 uniformly distributed around the central lobe 1. The central lobe 1 includes a central reflective panel 6 and a central base 8 fixedly connected to the back of the central reflective panel 6 , Multiple long ribs 9 and multiple short ribs 10; its fan-shaped petal 2 includes a fan-shaped reflective panel 7 and a reinforcement rib 14 fixedly connected to the back of the fan-shaped reflective panel 7; between the central petal 1 and the fan-shaped petals 2 and multiple pieces The fan-shaped lobes 2 are all connected in a detachable manner; the central reflective panel 6 and a plurality of fan-shaped reflective panels 7 together form the reflective panel of the antenna reflector.

[0028] The central reflective panel 6 and the fan-shaped reflective panel 7 both have a sandwich structure, including an aluminum honeycomb panel and carbon fiber inner and outer skin...

Abstract

The invention discloses a split-type high-precision all-composite material antenna reflector, which relates to the fields of wireless detection, satellite communication, electronic measurement and control, electronic interference and the like. The antenna reflector is a split-lobe structure, including a center lobe and a plurality of fan-shaped lobes uniformly distributed around the center lobe; the center lobe includes a center reflector panel and a center base fixedly connected to the back of the center reflector panel, a plurality of long Reinforcing ribs and multiple short reinforcing ribs; the fan-shaped petals include fan-shaped reflective panels and reinforcing ribs fixedly connected to the back of the fan-shaped reflective panels; the center petal and fan-shaped petals and multiple fan-shaped petals are connected in a detachable manner; the center The reflective panel and multiple fan-shaped reflective panels together form the reflective panel of the antenna reflector. The invention optimizes the split form of the large-diameter antenna, and at the same time integrates the design of the reflective panel and the reinforced back frame, has a stable structure, and is convenient for the transportation, erection and operation of the antenna reflector.

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 and the like, and is particularly suitable for antenna reflectors with light weight, fast disassembly and assembly, and high working frequency band requirements. Background technique [0002] With the continuous development of electronic technologies such as communications and measurement and control, parabolic antennas are not only widely used in the fields of remote wireless detection, satellite communications, and electronic measurement and control, but also the mobility, rapid response and working frequency of the antenna are becoming higher and higher. For large-aperture parabolic antennas, in order to meet the performance requirements of road transportation, it needs to be split and assembled. At present, traditional parabolic antennas basically adopt a sector-shaped equal division meth...
