Description

Technical Field

[0001] The utility model relates to the technical field of compact range testing, in particular to a feed turntable and a feed device for a compact range. Background Art

[0002] The compact range technology is a commonly used electromagnetic measurement technology, which is mainly used to test the far-field performance of antennas (including antenna pattern, directivity coefficient, omnidirectional radiation power, etc.) and the radar cross section (RCS) of targets. The processes of the two tests are different. When measuring the far-field parameters of an antenna, only the feed needs to receive the electromagnetic waves radiated by the antenna under test. While when measuring the radar cross section, two feed antennas need to work simultaneously, one for transmitting and the other for receiving. Due to the limitation of the operating frequency of the feed antenna, different frequency-band feeds need to be replaced during wide-band measurement. The above two situations are the two major factors restricting the test efficiency of the compact range. As long as these two problems can be solved, the test efficiency of the compact range can be greatly improved.

[0003] The frequency range of the compact range feed determines the frequency range of the compact range to a certain extent. The test frequency of the compact range is relatively wide, while the range of a single feed is relatively narrow. To achieve a wider frequency-band test, the compact range generally provides a set of feeds with different frequency bands to achieve full-frequency-band coverage. When performing antenna tests with different frequency bands in a system with a large frequency span, it is often necessary to replace the feed. Manually switching the transmitting and receiving feeds takes at least about 3 to 5 minutes, resulting in a great impact on the test efficiency. Therefore, there is an urgent need for an automatically switched compact range feed to achieve high efficiency in compact range measurement. Summary of the Utility Model

[0072] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments. The embodiments cannot be enumerated one by one here, but the embodiments of the present utility model are not limited to the following embodiments.

In this embodiment, the feed mounting seat 1 is coaxially arranged with the rotating shaft of the rotating seat 2; the support seat 3 is used to adjust the spatial position of the feed mounting seat 1 in the horizontal and vertical directions.

[0074] In this embodiment, the sizes and shapes of the plurality of feed mounting surfaces 1a on the feed mounting seat 1 are the same. Therefore, in the circumferential direction of the feed mounting seat 1, a uniform distribution of the plurality of feed mounting surfaces 1a is achieved. In this embodiment, for the convenience of installing the feed, mounting holes for installing the feed are correspondingly provided on each feed mounting surface 1a. Further, through the provided hollow feed mounting seat 1, test equipment such as a radio frequency switch, a microwave power amplifier, a vector network analyzer, and a radio frequency transceiver unit can be further installed inside the feed mounting seat 1 to facilitate the installation with the corresponding feed, effectively improving the integration degree of the present utility model.

[0075] Through the above settings, by setting the feed mounting base 1 on the feed turntable, multiple feeds can be set at intervals in the circumferential direction, effectively improving the integration of feed installation, making the volume of the feed device of the present utility model compact and enabling it to more easily adapt to the space limitations of the anechoic chamber. In addition, the multiple feed mounting surfaces 1a on the feed mounting base 1 of the present utility model all show an upward inclination, effectively ensuring the unity of the orientation. After each surface rotates to the test position, the positioning deviation ≤ 0.03 mm, thus effectively ensuring that the installation reference of each feed is consistent during the rotation process and effectively ensuring the test accuracy of the present utility model.

[0076] Combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in, according to an embodiment of the present utility model, the feed mounting base 1 includes: a first connecting ring 11, a second connecting ring 12, and a plurality of plate-shaped supports 13; wherein, the radial dimension of the outer edge of the second connecting ring 12 is smaller than the radial dimension of the outer edge of the first connecting ring 11, and along the up-down direction, the second connecting ring 12 and the first connecting ring 11 are coaxially arranged at intervals in sequence. In this embodiment, along the circumferential direction of the feed mounting base 1, a plurality of plate-shaped supports 13 are arranged in sequence; wherein, the upper end of the plate-shaped support 13 is fixedly connected to the edge of the second connecting ring 12, and the lower end of the plate-shaped support 13 is fixedly connected to the edge of the first connecting ring 11. In this embodiment, the outer side of the plate-shaped support 13 forms a feed mounting surface 1a, and the feed mounting surface 1a is arranged in one-to-one correspondence with the plate-shaped support 13.

[0077] In this embodiment, the first connecting ring 11, the second connecting ring 12, and the plurality of plate-shaped supports 13 can be made by an integral molding method. Of course, they can also be made by welding or threaded connection methods.

Furthermore, in the circumferential direction of the first connecting ring 1, the remaining side edges of adjacent plate-shaped supports 13 are separated. Specifically, since the length of the lower bottom plate of the plate-shaped support 13 is less than the length of the upper bottom edge, for this reason, the two side edges of the plate-shaped support 13 connected to the lower bottom edge are inclined in the direction of approaching each other. Thus, a triangular opening can be formed between adjacent plate-shaped supports 13 and the first connecting ring 11. On the one hand, the mass of the entire feed source mounting base 1 can be effectively reduced, and it is also convenient to install other structures through this opening.
