Problems solved by technology
But at the same time, it also brings a lot of negative problems: the antenna is exposed inside the building, which brings a sense of insecurity to the residents who pay more and more attention to "green environmental protection", causing them to resist radio waves, thus increasing the construction of wireless networks. difficulty
Especially with the advent of China's 3G era, more frequency bands will be opened for use, while the existing ceiling antennas often only work in one or two frequency bands, which cannot meet the diverse requirements of network optimization work

An ultra-wideband indoor beautifying ceiling antenna, comprising a dielectric radome, a cavity tapered radiator placed in the radome, a grounded metal reflector, and a mid-pass medium fixedly connected between the bottom of the radiator and the reflector A metal coupling structure located above the grounded metal reflector and surrounding the radiator is arranged at a distance from the radiator body. The shape of the metal coupling structure can match the shape of the radiator to couple the signal emitted by the radiator. The metal coupling structure The specific shape and position of the structure are determined by the performance requirements of the antenna. At least one of the radiator, the metal coupling structure and the grounded metal reflector is connected to the other two with a conductor. It can work at full frequency within the frequency band of 800MHz-4000MHz to achieve impedance matching and high gain. At the same time, the ceiling antenna has low height, small volume and is convenient for beautification, and its structure is simple and practical.
Description
technical field [0001] The invention relates to a ceiling antenna, in particular to an ultra-wideband indoor beautification ceiling antenna. Background technique [0002] Today's communication technology continues to develop at a high speed. In just a few decades, the world's mobile communication network has developed to the third generation. Today's communication network can not only provide people with voice services, but also provide data and Internet services, as well as other value-added services. Mobile communication network technology gradually meets people's ever-increasing living and working requirements. In order to provide higher-quality network services, mobile service operators have proposed the concept of full coverage and seamless coverage, and have continuously increased investment in network construction. But at the same time, it also brings a lot of negative problems: the antenna is exposed inside the building, which brings a sense of insecurity to the re...
