Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a multi-port suction cup combined antenna. Background Art

[0002] With the rapid development of satellite navigation technology and its wide application in various fields, higher and higher requirements have been put forward for the antenna characteristics of handheld receiving devices in high-precision satellite navigation and positioning systems. With the development of 4G / 5G mobile communication technology, especially after entering the 5G communication era, the speed of mobile Internet has been greatly improved, which is the choice for more terminals to access the network. Antennas are an important part of terminal products, responsible for transmitting and receiving signals. The antennas used in the existing technology are adjusted to the required frequency band through copper tubes and coils. Since the pitch and length of the coil are not easy to fix, the antenna will be unstable and difficult to debug. Since each coil can only reach one frequency band, there are many types of coils, so the bandwidth, radiation efficiency, gain and directional performance of the antenna directly affect the communication quality of terminal products. In order to meet the requirements of domestic multi-band operators, the bandwidth of 4G / 5G antennas in terminal products needs to cover 820-960MHz, 1710-2690MHz, and 3300-3600MHz.

[0003] In the patent of the Principality Patent Publication No. CN202797259U, a dual-coupled multi-frequency antenna is proposed. This antenna moves the second copper tube to change the coupling length between the first copper tube and the second copper tube, and between the second copper tube and the third copper tube to meet different frequency band requirements, and can meet different customer needs under the same material conditions. Therefore, an antenna of the utility model can replace several antennas, reduce the types of antenna coils, and save material delivery time. In addition, the dual-coupled multi-frequency antenna is simple to assemble, which can simplify the process, improve production efficiency, and thus reduce production costs. However, after studying the patent and the prior art, it is found that the currently commonly used full-band omnidirectional communication antenna still has the following problems: the coverage range of the antenna frequency is not wide enough to meet customer needs. Therefore, a multi-port suction cup combination antenna is proposed herein. Utility Model Content
