Abstract

Disclosed in the invention is a single-polarized omnidirectional ceiling antenna comprising a reflection base plate and a radiation oscillator arranged on the reflection base plate. The antenna is characterized in that a feeder gasket is arranged between the reflection base plate and the radiation oscillator. A top loading structure is arranged above the radiation oscillator and is connected to the reflection base plate in a short circuit mode. Besides, a fixed connecting element is connected between the radiation oscillator and the top loading structure; and the gap is formed between the radiation oscillator and the top loading structure. According to the invention, the antenna has a simple structure; the good directional diagram roundness, voltage standing wave ratio, and gain index of the antenna are realized. A problem of indoor coverage of wireless signals can be solved well. Compared with the same type of product, the provided antenna has the better performance.

Description

technical field [0001] The invention relates to the technical field of indoor distributed coverage equipment for mobile communication, in particular to an indoor single-polarized omnidirectional ceiling antenna. Background technique [0002] With the rapid development of wireless communication technology and the comprehensive popularization of information society, the development of mobile communication technology has become more and more important, and mobile users have higher and higher requirements for the capacity and quality of wireless communication. However, there are more and more high-rise buildings in modern society, the number of mobile users is increasing rapidly, and the coverage capacity and call density are also getting higher and higher. However, the number of mobile communication base stations is limited. In complex and changeable indoor environments such as high-rise buildings, large hotels, and conference rooms, it is difficult for mobile distribution syst...
