[0002] Phase shifters are key components of radar antennas, and their phase repeatability accuracy is directly related to the operational performance of phased array radar systems. Ferrite, as one of the key factors that determine the performance of phase shifters, is extremely sensitive to stress. At present, ferrite phase shifters mostly use phase shift units as the smallest replaceable units. The antenna array surface is large after discrete connection, and the length of the phase shift unit is usually significantly larger than the side length of the cross section. The slender shape easily produces adverse stress on the internal ferrite. Improving the mechanical properties of phase shifters, reducing the stress impact of device deformation on microwave materials, realizing the miniaturization and componentization design of phase shifters, and reducing the space requirements of phase shifters have become an important topic.

The independent phase shift units are integrated in the form of components, and the phase shift component can be installed at one time to connect several phase shift units, which is more convenient for users to use. The component design is conducive to the miniaturization of the antenna, while improving the mechanical properties of the phase shifter, enhancing the overall rigidity of the product, reducing the performance deviation of the ferrite due to stress, and reducing the stress effect of device deformation on the microwave material.

[0054] like Figures 1 to 7 As shown, further, the front plate 1 and the rear plate 2 are each provided with 8 pairs of waveguide openings, and the number of the phase shifting units 3 is 8 pairs.

[0055] The beneficial effects of adopting the above further technical solution are: optimizing the quantity and structure, making it easier for users to install and maintain the ferrite phase shifting components.

[0056] The embodiment of the present invention provides a ferrite phase shifting component. The component (ferrite phase shifting component) mainly includes: a phase shifting unit 3, a front plate 1, a rear plate 2, a driver 4, etc. The phase shifting unit 3 includes a phase shifting section, a transition section 33, etc.

[0057] The phase shift section includes an upper cavity 32 , a lower cavity 31 , microwave materials such as ferrite, a transfer plate 35 , a shielding plate 34 , and the like.

[0058] The driver 4 includes a mounting clip 42, an electrical connector 43, a printed circuit board 41 and various components mounted thereon.

[0059] The lower cavity 31 is provided with two threading holes on the front and back sides, and a buried wire groove 313 and an adapter plate groove 312 are provided between the two threading holes. The upper cavity 32 is arranged on the lower cavity 31, and the two together form the main body of the phase shifter. The upper and lower cavities (lower cavity 31 and upper cavity 32) are connected as a whole by threads, which is convenient for disassembly and assembly. The grooves on one side are opposite to each other, and the grooves on both sides jointly form a waveguide transmission line. At the same time, the left and right half flange surfaces of the upper and lower cavities are flush, forming complete flanges on both sides. The adapter plate 35 is arranged in the adapter plate groove 312 on the front and back sides of the lower cavity 31 of the phase shifter, with two on each side. The embedded adapter plate groove 312 can effectively prevent the adapter plate 35 from protruding from the lower cavity 31 and easily scratching the solder joints thereon.

[0060] The cables pass through the threading holes, along the buried cable groove 313, and finally gather in the middle of the upper cavity 32 (or lower cavity 31) of the phase shifter away from the groove. The buried cable groove 313 can provide protection for the cables. The shielding plate 34 is arranged at the final gathering point of the cables to play a wire pressing function, preventing the cables from being unconstrained and easily vibrated, pulled or scratched, and providing protection for the cables.

[0061] The mounting clips 42 are arranged on the two long sides of the printed circuit board 41, and the two are connected by threads and are detachable.

[0062] Waveguide ports are evenly arranged on the front plate 1 and the rear plate 2. One end of the phase shift unit 3 is connected to the waveguide port on the front plate 1, and the other end is connected to the waveguide port on the rear plate 2 to form an assembly. A driver 4 is arranged between every two rows of phase shift units 3 in the assembly. The driver 4 is used to drive the two rows of phase shift units 3. Compared with the traditional method of controlling one phase shift unit with one driver, this solution is more efficient and more convenient to connect and disassemble. The driver 4 is respectively installed with the front plate 1 and the rear plate 2 through two mounting clips 42 by threaded connection.

[0063] In a preferred embodiment, the phase shifting assembly integrates the phase shifting unit 3 in the form of an assembly, which effectively enhances the overall rigidity of the product and significantly reduces the performance deviation caused by the stress on the ferrite.

[0064] In a preferred embodiment, all the phase shifting units 3 in the phase shifting assembly are controlled by a driver 4 , which greatly reduces the overall size of the device compared to the traditional solution of one driver controlling one phase shifting unit.

[0065] In a preferred embodiment, the phase shifting component only requires one driver 4, and the driver 4 needs to be connected to an external device and transmit signals through an electrical connector. Compared with the traditional solution of one driver controlling one phase shifting unit, the electrical connectors required for the same number of phase shifting units are reduced from several to only one, which facilitates connection and reduces costs.

[0066] In a preferred embodiment, the driver 4 of the phase shifting assembly requires fewer components. In the conventional solution of one driver controlling one phase shifting unit, each driver may have the same components, but in the driver in the form of an assembly, since they are on the same printed circuit board 41, some of the same components can be shared, which reduces the number of components and also reduces the cost of the product.

[0067] In a preferred embodiment, two rows of 16 waveguide ports are evenly arranged on the front plate 1 and the rear plate 2, and each component has 16 phase shifting units 3. This number can be optimized and adjusted according to actual conditions.

[0068] In a preferred embodiment, heat dissipation teeth (second heat dissipation teeth 322 and first heat dissipation teeth 314) are provided on one side of the upper cavity 32 and the lower cavity 31 away from the groove, which is helpful for controlling the temperature rise during the use of the device.

[0069] In a preferred embodiment, the phase shifting assembly can be installed once to connect several phase shifting units 3, which is more convenient for users to use. However, the discretely connected phase shifting units need to be installed one by one, which is a huge workload for a large number of antenna arrays.

[0070] In a preferred embodiment, the shielding plate 34 can effectively restrict the movement of the cable, preventing the cable from being easily scratched due to position change caused by vibration during operation and movement, and at the same time, the shielding plate 34 provides physical protection for the cable it wraps.

[0071] In a preferred embodiment, the cable embedding groove 313 and the adapter plate groove 312 can better protect the cables and the adapter plate 35, and also play a good fixing role.

[0072] In a preferred embodiment, the mounting clamp 42 is connected to the drive plate (printed circuit board 41) by threads, and is also connected to the front and rear plates (front plate 1 and rear plate 2) by threads, so that the drive plate is reliably fixed together with the front and rear plates.

[0073] In a preferred embodiment, the mounting clamp 42 is designed with a round hole on one side and a U-shaped hole on the other side. The round hole can ensure that the screw or bolt passes through the position accurately and its head is clamped outside the mounting clamp 42, while the U-shaped hole on the other side can tightly clamp the nut connected to the screw or bolt to prevent the nut from rotating, thereby facilitating installation.

[0074] In a preferred embodiment, the upper cavity 32 and the lower cavity 31 are connected by threads (threaded connection can be connected by bolts or screws), and are positioned by pins (locating pins) to ensure that the inner walls of the grooves of the upper and lower cavities are aligned and flush, reducing device losses and avoiding breakdown and sparking under high power conditions. Similarly, pins are also used for positioning on the flange connection surfaces of the transition section 33 and the phase shift section to achieve good centering between the two.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
