Embodiment Construction

[0033]The invention will be further described below with reference to the accompanying drawings.

[0034]The embodiment of the present invention provides an antenna cover of an integrated polarizer function, which is mainly composed of a fiber cloth, a polarizer, and a support plate, and a partial structure of the antenna cover.figure 1 Indicated.

[0035]The main structure of this antenna cover is used to select a fiber cloth. In this embodiment, the fiber is selected for the glass cloth, and there is a multi-layer polarizer in the antenna cover. The multilayer polarizer is stacked in accordance with the corresponding angle and sequential. A support plate is also laid between the polarizers, and thereby retains a certain spacing between each layer polarizer, and the support plate and polarizer are bonded together by the glue.

[0036]The area where the polarizer is located is the transmission area of ​​the antenna cover, which effectively utilizes the support plate to increase the rigidity ...

Abstract

The invention relates to the technical field of antennas, and discloses a radome integrated with a polarizer function, and a manufacturing method thereof. The radome is mainly composed of fiber cloth,polarizers and supporting plates, the fiber cloth serves as a main structure of the radome, the polarizers are flatly laid in the radome and stacked according to the corresponding angle and sequence,and the supporting plates are laid in each layer of polarizers; and a certain spacing size is guaranteed, all the binding faces are bonded through glue, overall vacuumizing is conducted after assembling is completed, and then high-temperature co-curing is conducted. According to the radome provided by the invention, a polarizer mounting structural member is omitted, so that the weight and the space are effectively reduced; and meanwhile, the influence of the position precision error of the structural member on the electrical performance of the antenna is eliminated, and the reliability and the environmental adaptability of the system are improved.

Description

Technical field[0001]The present invention relates to the field of antenna, and more particularly to an antenna cover that improves an antenna product integration, reliability and an environmentally adaptive integrated polarizer function.Background technique[0002]The antenna cover is a structure that protects an antenna from an external environment, requiring good electromagnetic wave penetration characteristics, and withstanding mechanical properties of external harsh environments. The polarizer is a device that controls the direction of the antenna polarization, is used to select a polarization pattern consistent with the demand signal, and suppress other types of polarization waves to obtain polarization matching, and achieve optimal reception. Typically, the antenna polarizer and the antenna cover are mounted in a certain position between the antenna mouth and the antenna cover.[0003]The existing technique is that the antenna cover is mounted independently of each other. The pol...
