This method requires multiple tests, is inefficient, wastes manpower, is inconvenient to operate, and makes it difficult to connect the ceramic antenna feed pins to the fixtures. Furthermore, it requires multiple network analyzers, occupying expensive testing equipment. Utility Model Content

[0037] Reference Figures 1 to 5In some embodiments, an antenna test fixture according to the present invention is described with reference to... Figure 1 ,include:

[0038] The fixture body 1 includes an installation and testing section 2 for mounting an antenna and a wiring section 3 for connecting a network analyzer.

[0039] The installation and testing unit 2 includes a mounting block 21 for mounting the antenna under test and a plurality of positioning blocks 24, the positioning blocks 24 being arranged around the mounting block 21.

[0040] The beneficial effects of this utility model are as follows:

[0041] In this application, the antenna test fixture is a multi-feed ceramic antenna test fixture, which can be used in scenarios where multi-feed ceramic antennas are tested simultaneously, achieving the technical effects of high testing efficiency and improved consistency of test results.

[0042] Specifically, in view of the existing technology, this paper proposes a convenient test fixture to address the problems of low efficiency, inconvenient operation, and expensive test equipment required by existing multi-feed ceramic antenna test fixtures.

[0043] The technical solution adopted in this application is to construct a test fixture for multi-feed ceramic antennas, including a positioning block 24, a spring, a mounting block 21 and a fixture body 1. For multi-feed ceramic antennas, simultaneous testing is possible, achieving high efficiency and consistent and stable test results.

[0044] In some embodiments, the ceramic antenna relies on multiple positioning blocks 24, making it easy to place into the fixture for testing. The feed pins of the ceramic antenna can be easily inserted into the holes of the corresponding insulating rings, improving work efficiency. Even with a 0.1-0.2mm tolerance in the spacing between the feed pins, the ceramic antenna can still make close contact with the corresponding springs, resulting in stable test results. The small diameter of the structure connecting the silver-plated copper pins and the springs allows for the fabrication of multiple sets of silver-plated copper pin and spring connection structures within the mounting block 21, enabling simultaneous testing of ceramic antennas with multiple feed pins and improving work efficiency. The short length of the structure connecting the silver-plated copper pins and the mounting block 21 reduces the impact of the fixture on the performance of the ceramic antenna, improving test accuracy. The spring material is wear-resistant, elastic, and has a long service life, making replacement of worn springs simple and convenient, facilitating maintenance.

[0045] In some embodiments, the ceramic antenna is placed into the fixture by means of the positioning block 24, and the feed pin of the ceramic antenna is easily inserted into the hole in the corresponding insulating ring. The inner area enclosed by the positioning block 24 is 0.2 mm larger than the ceramic antenna, and the inner side is chamfered, so the ceramic antenna can be easily placed into the inner area enclosed by the positioning block 24, and the feed pin of the ceramic antenna is also aligned with the center hole of the corresponding insulating ring.

[0046] Furthermore, refer to Figures 2 to 4 The mounting block 21 is provided with at least one set of test holes.

The second insulating rubber ring 2124 is installed in the second mounting hole 212.

[0050] Specifically, the first mounting connector 2111 is installed by welding the first insert spring 2112 and the first silver-plated copper pin 2113 together, then inserting them into the first insulating rubber ring for tight fit and fixation, and then installing the whole assembly into a set of test holes in the mounting block 21.

[0051] The second mounting connector 2121 is installed by welding the second spring 2122 and the second silver-plated copper pin 2123 together, then inserting them into the second insulating rubber ring 2124 for tight fit and fixation, and finally installing the whole assembly into a set of test holes in the mounting block 21. The test holes for the second mounting connector 2121 are in the same set as those for the first mounting connector 2111.

[0052] It also includes fixing the mounting block 21 to the fixture body 1, and then using screws to fix multiple positioning blocks 24 to the fixture body 1.

[0053] In some embodiments, the first insulating ring is segmented, including a first insulating ring for wrapping the first spring 2112 and a second insulating ring for wrapping the first silver-plated copper needle 2113; the second insulating ring 2124 is segmented, including a third insulating ring for wrapping the second spring 2122 and a fourth insulating ring for wrapping the second silver-plated copper needle 2123.

[0054] Furthermore, refer to Figure 5The first mounting connector 2111 is connected to the wiring part 3 via the first coaxial cable 22, and the second mounting connector 2121 is connected to the wiring part 3 via the second coaxial cable 23.

[0055] Furthermore, refer to Figures 3 to 5 Both the first coaxial cable 22 and the second coaxial cable 23 are SMA male-female coaxial cables.

[0056] At the connection between the first coaxial cable 22 and the mounting block 21, the core wire of the first coaxial cable 22 is soldered to the lower end of the first silver-plated copper pin 2113, and the braid of the first coaxial cable 22 is soldered to the mounting block 21.

[0057] At the connection between the second coaxial cable 23 and the mounting block 21, the core wire of the second coaxial cable 23 is welded to the lower end of the second silver-plated copper pin 2123, and the braid of the second coaxial cable 23 is welded to the mounting block 21.

[0058] Specifically, two SMA male and female pins are used as a coaxial line, in which the core wire part is welded to the corresponding silver-plated copper pin, and the braided part is welded to the mounting block 21.

[0059] Furthermore, the mounting block 21 is disposed at the center of the top surface of the fixture body 1, and the positioning block 24 includes a first positioning block 241, a second positioning block 242, a third positioning block 243, and a fourth positioning block 244 respectively disposed at the four corner positions of the mounting block 21.
