Component for adjusting tunable antenna and tunable antenna system

Abstract

The invention relates to a component for adjusting a tunable antenna. The component for adjusting the tunable antenna comprises a control device, a motor, a cable and a shielding material, the controldevice is connected with the motor through the cable, and the shielding material comprises aluminum foil glass fiber cloth. The shielding material composition of the aluminum foil glass fiber cloth can improve the electromagnetic shielding effect, particularly the passive intermodulation effect of the tunable antenna system. The present invention further relates to a method for manufacturing thecomponent for adjusting the tunable antenna.

Description

technical field [0001] The present invention relates to the field of radio frequency products, in particular to an assembly for adjusting an electric antenna and an electric antenna system having the assembly for adjusting the antenna. The invention also relates to a method for producing an assembly for adjusting an electrically adjustable antenna. Background technique [0002] With the large-scale construction of mobile communication networks (such as 3G and 4G), more and more standards and frequency bands are put into use, and the density of base stations is increasing. The coverage within the cell and the interference between cells are becoming increasingly prominent. How to achieve good coverage is one of the current research hotspots. Compared with traditional mobile communication base station antennas, which require manual pole climbing to adjust the antenna, the electric downtilt of the electric adjustable antenna can be automatically adjusted at different times usin...

Problems solved by technology

However, the currently commonly used shielding materials (magnesium, copper, nickel and aluminum electromagnetic shielding materials) have a series of disadvantages. For example, in order to enhance the tensile strength of the shielding material, the shielding material will be made thicker, but this will make the shielding material It becomes harder, and the fit becomes poor, especially when the shielding object is a flexible device, the shielding material is prone to bending, so that a gap is formed between the shielding material and the surface of the shielding object, which in turn will significantly reduce the electromagnetic shielding of the entire system Effect

Conversely, reducing the thickness of the shielding material in order to achieve better fit will make the tensile strength of the shielding material weaker and easily damaged or broken, thus greatly reducing the electromagnetic shielding effect and increasing the manufacturing and maintenance costs
