Ultra-wideband dual-polarization bidirectional coverage antenna

Abstract

The invention discloses an ultra-wideband dual-polarization bidirectional coverage antenna, which relates to the technical field of mobile communication. The ultra-wideband dual-polarization bidirectional coverage antenna comprises a first reflecting plate and a second reflecting plate, wherein the first reflecting plate and the second reflecting plate are arranged according to a certain includedangle; each of the first reflecting plate and the second reflecting plate is provided with a low-frequency radiation unit, an intermediate-frequency radiation unit and a high-frequency radiation unit.The ultra-wideband dual-polarization bidirectional coverage antenna has the characteristics of ultra wideband, dual polarization, bidirectional coverage, convenient mounting and the like, the ultra wideband can cover multiple network systems, coverage application in scenes such as tunnels, subways, streets, highways, railways and roads in villages in cities can be met, the array arrangement design is compact, the peripheral dimension of the antenna is reduced, and antenna mounting and later maintenance difficulties are reduced. The antenna supports polarization diversity, and in comparison with an early single-polarization bidirectional coverage antenna, the coverage performance is greatly enhanced; and the ultra-wideband performance far exceeds an early bidirectional antenna, network sites can be reduced, and the network construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an ultra-wideband dual-polarized bidirectional coverage antenna. Background technique [0002] With the rapid development and evolution of mobile communication technology in recent years, mobile users' demand for communication has risen from basic voice calls to fast and stable data experience. This is undoubtedly a new challenge for operators. In addition to meeting the basic service requirements of the communication system with more base stations, it is also necessary to concentrate efforts to optimize the network and improve services to maximize the quality of network coverage or increase the coverage area, thereby improving customer experience and bringing greater benefits to operators. income.

Problems solved by technology

When doing network optimization, you will encounter some unconventional scenarios, such as tunnels, subways, streets, highways, railways, roads in urban villages, etc. It will be very difficult to use conventional base station antennas for network coverage in such areas , mainly because the site space is small, and conventional base station antennas cannot be installed. The early method is to use leaky cables to cover, but the cost of leaky cables is too high, which will increase the cost of operators; leaky cables are gradually eliminated and replaced by Bi-directional log-periodic antenna, this type of antenna has low cost and better coverage effect, but it is difficult to achieve dual polarization, and thus polarization diversity cannot be achieved, and it is difficult to match the demand in the case of a large increase in data services
