The antenna manufactured according to the invention has strong environment applicability, low standing-wave ratio, high isolation degree, excellent antenna performance and a simple and compact structure.

Description

【Technical field】 [0001] The invention relates to mobile communication coverage technology, especially MIMO (Multiple Input Multiple Output) related technology of mobile communication indoor distribution system, and specifically relates to a broadband dual-polarized omnidirectional ceiling antenna. 【Background technique】 [0002] The indoor distribution system is an important part of today's wireless communication system, and the performance of the indoor distribution antenna directly affects the overall performance of the system. With the rapid development of mobile communication systems, the complexity of the system is getting higher and higher, which also puts forward new requirements and challenges for the performance of the antenna. Moreover, as users' awareness of protection against antenna radiation increases, stricter requirements are placed on the size of the indoor distribution system. Therefore, designing and adopting a new type of miniaturized and high-performan...

AI Technical Summary

Problems solved by technology

Although the technical solution claims that it has achieved a relatively good technical effect, the experiment conducted by the applicant using the technical solution shows that the technical solution cannot achieve the claimed effect. Therefore, it is doubtful whether the technical solution is feasible

The applicant believes that the upper conical vibrator and the lower conical vibrator are aligned and connected, and the magnetic field formed at the alignment position of the two is the strongest, and the horizontally polarized antenna is set at this position, which will affect the standing of the vertically polarized antenna. The wave brings a great degree of interference, and also makes the ceiling antenna unable to be miniaturized

Moreover, the ceiling antenna should pursue the overall technical effect, but for the situation where vertically polarized antennas and horizontally polarized antennas are installed in the ceiling antenna at the same time, this technical solution does not consider solving the problem of high isolation caused by it
