Abstract

The invention belongs to the technical field of communication and radar antenna system components. The invention discloses an L-shaped ultra-wideband waveguide rotary joint, a control system, a control method and application, a coaxial transition structure is adopted, and an arc surface periodic metal convex body array with embedded balls is matched with a cylindrical shielding cavity at the coaxial transition part to form rotatable coaxial transition of an electromagnetic band gap structure type; electromagnetic shielding is achieved through the electromagnetic forbidden band characteristic of an electromagnetic band gap structure, electromagnetic signal transmission to the position between an upper waveguide and a lower waveguide is achieved through broadband terminating type and orthogonal type coaxial-waveguide conversion, and an L-shaped waveguide rotating joint is formed in cooperation with a bearing. According to the invention, a ball supporting type rotatable electromagnetic band gap structure is constructed at a rotating part, so that high electromagnetic transmission performance of the rotating joint in an ultra-wideband range is ensured while stable rotation is realized,and certain wear resistance can be realized under a proper size; meanwhile, the power capacity and the mechanical structure reliability of the rotary joint are improved through the ball-supported contact structure.

Description

technical field [0001] The invention belongs to the technical field of communication and radar antenna system components, and in particular relates to an L-shaped ultra-broadband waveguide rotary joint, a control system, a method and an application. Background technique [0002] Today, rotary joints are important components in communication and radar antenna systems. In order to realize the continuous search, tracking and measurement of the target, it is usually required that the radiation mechanism of the antenna can realize 360° continuous rotation, and at the same time, it is necessary to ensure the uninterrupted transmission of electromagnetic signals during the rotation process. Therefore, a rotary joint must be used in the antenna feed system. In order to ensure that the microwave signal can be continuously and effectively transmitted during the rotation of the antenna. [0003] Currently, rotary joints include waveguide rotary joints and coaxial rotary joints. The w...
