Problems solved by technology

[0003] In order to transmit radio signals in different directions and receive them from different directions, a phase shifter is needed to change the phase of the radio signal. Most of the previous phase shifters are components made of metal materials, and the efficiency of signal coupling is not good. And because the signal is transmitted in a contact way, noise will be generated when changing the phase shift amount. In addition, the volume of the previous phase shifter is also quite large, which does not meet the short, small, light and thin design. trend
Another problem is that because the previous phase shifters are made of metal mechanical structures, there will be more manufacturing procedures in the manufacture.
[0005] Although the manufacturing method of the above-mentioned phase shifter has greatly simplified and reduced the structure and volume of the conventional phase shifter, there is still room for improvement in the manufacturing process of the operating mechanism of the movable dielectric element.

Abstract

An adjustable antenna phase shifter comprises a metal circuit part, a coupling part and a grounding part, wherein the metal circuit part is used for receiving a feed-in signal; the coupling part is arranged on one side of the metal circuit, forms an included angle with the metal circuit part and controls the phase angle of the feed-in signal by adjusting the included angle; and the grounding part is arranged on the other side of the metal circuit part for adjusting the phase angle output by the phase shifter through the simple mechanical structure, thereby improving the manufacturing efficiency of the phase shifter, and meanwhile, by adopting an adhesive impedance matcher or changing the shape structure of the phase shifter, the convenience of the phase shifter manufacture can be further improved.

Description

technical field [0001] The invention relates to an antenna phase shifter, in particular to an adjustable antenna phase shifter. Background technique [0002] With the development of wireless communication technology, various products and technologies applied to multi-frequency transmission are constantly coming out. Many electronic products have the function of wireless communication to meet the needs of consumers. Antennas are used in wireless communication systems to transmit and receive An important component of electromagnetic wave energy is generally a dipole antenna (Dipole antenna) or a helical antenna (Helical antenna) and so on. [0003] In order to transmit radio signals in different directions and receive them from different directions, a phase shifter is needed to change the phase of the radio signal. Most of the previous phase shifters are components made of metal materials, and the efficiency of signal coupling is not good. And because the signal is transmitte...
