Description

Technical Field

[0001] The present invention relates to an antenna fixing device, and in particular to an installation fixing device and an installation process for a high-density cross antenna. Background Art

[0002] As the size of entire systems continues to shrink, the requirements for antenna array integration are becoming increasingly demanding. Traditionally, antenna arrays have two methods for mounting and fixing them. One method uses antenna strips, each with screw holes secured to the baseplate by screws to form the antenna array. This method requires a fixed position for the mounting screws and is only suitable for multi-row antennas, not cross-shaped antennas. Another method uses flanges for the RF coaxial connectors on the antenna strips, which are secured to the baseplate by screws. This method is commonly used in cross-shaped antennas, but it results in larger spacing between the antennas. When hundreds or thousands of antenna elements are integrated, the resulting size is too large to meet the requirements for a small, high-integration system. Therefore, a high-density cross-shaped antenna mounting and fixing device is urgently needed to address this issue. Summary of the Invention

A plurality of No. 1 RF coaxial connectors are horizontally mounted on the upper portion of the front end of the base plate, and the No. 1 antenna board is welded and fixed to the upper end of the front end of the No. 1 RF coaxial connector.

[0007] On the basis of the above technical solution, the No. 2 RF coaxial connector includes a No. 1 insulator, a No. 1 inner conductor, a shell, a No. 2 insulator, a No. 2 inner conductor, and a No. 2 connector structure.
