Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a copper tube multi-frequency antenna. Background Art

[0002] With the rapid development of satellite navigation technology and its wide application in various fields, higher and higher requirements are put forward for the antenna characteristics of handheld receiving devices in satellite navigation positioning systems for high-precision measurement. And with the development of 4G / 5G mobile communication technology, especially after entering the 5G communication era, the network speed of mobile Internet has been greatly improved, which is the choice for more terminals to access the network. An antenna is an important component of terminal products, responsible for signal transmission and reception. The antennas used in the prior art adjust the required frequency bands through copper tubes and coils. Since the pitch and length of the coils are not easy to fix, it will cause problems such as unstable antennas and difficult debugging. Also, since each coil can only achieve one frequency band, resulting in a large variety of coil types, the performance of the bandwidth, radiation efficiency, gain, and radiation pattern of the antenna directly affects the communication quality of terminal products. The 4G / 5G antennas in terminal products need to cover 820 - 960 MHz, 1710 - 2690 MHz, and 3300 - 3600 MHz to meet the requirements of domestic multi-band operators.

[0003] In the patent with the public patent number CN202797259U in China, a dual-coupled multi-frequency antenna is proposed. By moving the second copper tube to change the coupling lengths between the first copper tube and the second copper tube, and between the second copper tube and the third copper tube, different frequency band requirements can be achieved, and different customer needs can be met under the same material conditions. Therefore, one antenna of the utility model can replace several antennas, reducing the types of antenna coils and saving the material issuing time. In addition, the assembly of the said dual-coupled multi-frequency antenna is simple, which can simplify the process, improve production efficiency, and thus reduce production costs. However, after researching the prior art and the above patent, it is found that it is difficult for the existing antennas to meet the requirements of different frequency bands on the premise of ensuring the stability of the antenna and easy debugging. Therefore, the utility model hereby proposes a copper tube multi-frequency antenna. Summary of the Utility Model
