Problems solved by technology

This method has two defects. One is that any switch has a corresponding contact direction. When the impact direction is inconsistent, it will not cause the switch to be powered off. The other is that the inertia of the stall is relatively large. Hit the antenna, weakening the protection

Embodiment Construction

[0012] The present invention is described in detail below in conjunction with the accompanying drawings of the description. The design idea of ​​the present invention is to avoid the hard contact between the cover wall and the antenna in the stall state and buffer the impact between the two through structural design without changing the performance index of the horn antenna. It can significantly reduce the damage of the product and the measurement system under the stall state of the measurement system, and especially play an important role in the protection of the radome.

[0013] Such as figure 1 As shown, it is a structural schematic diagram of the present invention. The structure adopts a double protection design form. A proximity switch 3 is arranged between the antenna 1 and the radome cover wall 4 to form the first protection. The proximity switch 3 is close to the radome cover. The wall 4 automatically responds to prevent the antenna 1 from approaching the radome cover ...

Abstract

The invention belongs to the field of electrical performance of radome, and specifically relates to an antenna structure with protection function. The structure adopts a double protection design form. A proximity switch is arranged between the antenna and the wall of the radome to form a first protection mechanism. The proximity switch Automatically respond when approaching the radome cover wall, preventing the antenna from approaching the radome cover wall; the antenna is provided with a protective collar, which prevents the antenna from contacting the radome cover wall and causing damage to the antenna, and the protective collar constitutes the second protective body. The invention belongs to the field of electrical properties of a radome, and in particular relates to a protective function antenna structure.

Description

technical field [0001] The invention belongs to the field of electrical properties of a radome, and in particular relates to a protective function antenna structure. Background technique [0002] Automatic electrical thickness measurement and correction of radome is an important technical guarantee for high-performance electromagnetic window products. The electrical thickness technique itself is a macroscopic parameter when the electrical size of the measured material is much larger than the wavelength, and it is an average effect. In order to improve the measurement resolution of the electrical thickness out-of-tolerance area, it is required that the single-point measurement area must be as small as possible. All antennas have a radiation function, which makes it impossible to consider the measurement distance of the antenna in a large way. Considering various factors, the minimum distance between the outer edge of the antenna and the cover wall must be kept within 10mm. ...
