Therefore, by utilizing the characteristics of light control, the signal interference is reduced, the response speed is improved, the integration process is simplified, the superiority is that the reliability of the antenna is improved, the size of the antenna is reduced, and a new electromagnetic wave regulation and control means and a hardware basis are provided for a modern communication system.

This utility model relates to the field of low-voltage switchgear technology, specifically an interlocking mechanism for a movable drawer unit and the movable drawer unit itself. The interlocking mechanism includes a position interlocking mechanism, comprising a position interlocking drive plate and a movable portion position locking plate. The movable portion position locking plate is located on the back of the movable drawer unit and is fixed to the movable portion. The position interlocking drive plate is positioned by embedding a positioning element into a corresponding position positioning hole on the movable portion position locking plate. The fixed and movable portions of the movable drawer unit are interlocked through the aforementioned interlocking mechanism. The advantages are: the interlocking mechanism has complete functions, low structural cost, small space occupation, and enables unit miniaturization; the use of T-shaped sliding columns and guide rails for push-guided limiting reduces the precision requirements of sheet metal parts processing, lowers costs, solves push-up failures, controls the upward tilting of the rear of the movable portion, and also increases the internal width of the unit.

The broadband high-gain transmission array antenna comprises a pyramid horn antenna and a transmission array, the transmission array comprises a plurality of transmission units, and each transmission unit comprises a dielectric substrate, an upper-layer metal patch and a lower-layer metal patch. The upper layer metal patch and the lower layer metal patch respectively etch the upper surface and the lower surface of the dielectric substrate. The upper-layer metal patch and the lower-layer metal patch are each of a sector ring and circular ring stacked structure, and phase regulation and control are achieved by controlling the opening angle of the outermost sector ring. In addition, the 360-degree phase range can be obtained by mirroring the upper metal patch and the lower metal patch. Compared with a traditional high-gain broadband transmission array antenna, the single-layer dielectric substrate is used, metal through holes and metal columns are prevented from being used, the unit structure is simpler, and the profile height is effectively reduced; compared with an existing low-profile transmission array antenna based on a single-layer dielectric substrate unit, the low-profile transmission array antenna has the advantages that the gain bandwidth and the aperture efficiency are remarkably improved, and the application scene is wider.

This invention belongs to the field of antenna engineering technology, specifically providing a 1-bit encoded wide-bandwidth angle-scanning reflective array antenna to achieve high-speed, low-cost beam scanning with wide-bandwidth angle-scanning characteristics. This invention employs a wide-bandwidth horn feed and dipole antenna elements. The element structure uses a phase delay line with short-circuited terminations to control the phase, which not only provides wide-bandwidth characteristics but also minimizes inter-element coupling and mutual influence, suppressing resonance. Furthermore, the DC control structure is simple, significantly reducing the number of electronic control components and lowering the complexity of the electronic control method. In summary, this invention utilizes a stripline transmission line to achieve wide-bandwidth, low-loss linear phase shift and employs 1-bit encoding for high-speed, low-cost array phase electrical modulation to achieve wide-bandwidth angle-scanning, offering advantages such as simple structure and convenient electronic control.

This utility model relates to the field of low-voltage switchgear technology, specifically a movable drawer unit, comprising a fixed part and a movable part. The fixed and movable parts are connected by a slidable connection structure, allowing them to be slidably connected back and forth. The bottom of the movable part has a T-shaped sliding column, which engages with the guide rail inside the unit chamber for guiding and limiting the movement. The advantages of this utility model are: the T-shaped sliding column of the movable part engages with the guide rail inside the unit chamber for guiding and limiting the movement, solving the problem of movement failure and controlling the upward tilting of the rear of the movable part; furthermore, the clearance between the movable connection structure of the fixed and movable parts is no longer related to the movement limit, eliminating stress and the need to control the clearance, simplifying the unit structure, reducing the precision requirements for sheet metal parts processing, lowering costs, and reducing steel plate usage; and also increasing the internal width of the unit.
