A Broadband Window Type Adjustable Inverted Cone Electromagnetic Structure

Abstract

The invention provides a broadband window type adjustable inverted cone electromagnetic structure. The top surfaces of cone frustums of two coaxial radiators are formed oppositely and are fixedly connected onto a connecting flange through a medium supporting part, wherein each radiator is shaped like an inverted cone; a coaxial middle radiation pipe is fixedly connected into the inverted-cone-shaped radiators; an internal radiation pipe coaxially penetrates the two inverted-cone-shaped radiators; the side wall of the medium supporting part is open; an opening is formed at the corresponding position of the connecting flange along the circumferential surface; a coaxial external radiation cylinder surrounds the outer sides of the cone frustums of the coaxial radiators; the external radiation cylinder is fixedly connected with the outer wall of the medium supporting part through a medium ring so as to block the opening of the medium supporting part; a tuning resistance sliding block slides between the internal radiation pipe and the middle radiation pipe and is fixedly connected with a tuning ring through an axial groove which is formed in the middle radiation pipe. According to the broadband window type adjustable inverted cone electromagnetic structure, the convenience in the tuning process is improved, the positions of tuning sliding blocks can be maintained to be concentric, the problem of the installation and maintenance of feeder lines is solved, and the stability of the structure is improved.

Description

technical field [0001] The invention relates to the technical field of composite adjustable inverted cone broadband electromagnetic structures. Background technique [0002] In order to realize the symmetrical structure of the inverted cone, the traditional method is that the internal adjustment structure realizes the tuning resistance function through the change of the screw position, and fixes it on the middle radiating tube; the two inverted cones are fixedly connected to the radiating tube at the junction through the integrated radome, The radiating tube is connected to symmetrical flanges, two sets of inverted cones and the radome at the joints. This structural form cannot guarantee the stability of the overall structure. The radiating tube bears a large structural gravity, which brings great impact on antenna assembly and debugging. inconvenient. [0003] The traditional symmetrical inverted cone structure design method is: the inverted cone antenna slider is tuned an...

AI Technical Summary

Problems solved by technology

[0004] 1. Use screws to fix the tuning slider, which may easily cause the slider to be eccentric in the middle radiation tube, and the four fixing screws may not be on the same horizontal plane, which will cause inconvenience to tuning

[0005] 2. In the traditional structural design, the radiation tube bears a large structural gravity, which is unfavorable to the structural reliability design. After the radiation tube and the radome are integrated and installed, it is impossible to perform maintenance and tuning of the internal feeder system, which brings inconvenience to installation and maintenance
