Title:
ULTRA-WIDEBAND DUAL-POLARIZATION TWO-WAY COVERAGE ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/223304
Kind Code:
A1
Abstract:
Provided is an ultra-wideband dual-polarization two-way coverage antenna, relates to the moving communication technology field, comprising a first reflecting plate and a second reflecting plate, the first reflecting plate and the second reflecting plate are disposed at a certain angle; the first reflecting plate and the second reflecting plate are provided with a low frequency radiating unit, an intermediate frequency radiating unit and a high frequency radiating unit; the antenna has the features of ultra-wideband, dual polarization, two-way coverage, convenient installation and the like, the bandwidth of the ultra-wide band can cover a variety of network standards, and satisfy the cover application of the scenes such as road of tunnel, subway, street, highway, railway and villages within the city, the compact array arrangement design reduces the outer dimension of antenna, and reduces the difficulty of installation and subsequent maintenance of antenna. The antenna supports polarization diversity, and the coverage performance is greatly improved compared with the early single-polarization two-way coverage antenna; the ultra-wideband performance is far superior to early two-way antennas, reducing network sites and network construction costs.
