Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] see figure 1 Shown is a schematic cross-sectional view of a radome 1 of the present invention, which can clearly reveal that the radome 1 of the present invention, as a finished product, is an integrally formed part, and the whole is in a longitudinal shape, and adopts a subsequent molding process suppressed. The radome 1 has a virtual longitudinal section (see figure 1 Section boundary line OO', which is the imaginary section where the boundary line is located), is divided into an upper cover 11 and a lower cover 12. The upper cover 11 has a hollow material structure, and a single-layer glass fiber hollow fabric blank is used as the main body. Prepreg, if necessary, add other known commonly used additives, thereby making a prepreg sheet 4 (see Figure 4), from which the sheet is further molded. Since the glass fiber hollow fabric has two u...

Abstract

The invention mainly relates to an antenna cover which is of a cylindrical structure which is integrally formed. The antenna cover comprises an upper cover with a hollow material structure and a lower cover with a compact material structure, wherein the upper cover and lower cover are divided by an invisible longitudinal section, and the upper cover and the lower cover are subjected to integrated compression molding. In addition, the invention relates to an antenna adopting the antenna cover, a mould for preparing the antenna cover as well as an antenna cover forming process for manufacturing the antenna cover. The process mainly adopts compression molding so as to obtain the antenna cover with a closed profiled bar structure. The invention provides the mould and the forming process and the like for improving the antenna cover based on the same idea, the antenna cover obtained by the idea has the closed profiled bar structure, excellent electromagnetism wave-transparent property and mechanical property can be achieved and are supported by measured data, and the antenna cover is simple in process, low in cost and is beneficial to volume production and popularization and application in the antenna.

Description

technical field [0001] The invention relates to a communication antenna, and further relates to a radome used therein, as well as a mold and a molding process for molding the radome. Background technique [0002] As we all know, mobile communication antennas are receiving and transmitting equipment for electromagnetic wave signals. All mobile communication antennas usually need to be equipped with radome, and the radome has different effects on the radiation index and circuit index of the antenna due to different material characteristics. [0003] The influence of the radome on the electrical performance of the antenna is mainly reflected in two parameters: the dielectric constant of the radome and the loss tangent. Effectively reducing these two parameters, especially the value of the dielectric constant, will help reduce the adverse effects of the radome on the electrical performance of the antenna. [0004] Yet, in the prior art, the dielectric constant that is used for ...
