Abstract

The invention relates to the technical field of dual-polarization radiating units and discloses an ultra-wideband dual-polarization radiating unit and an array antenna comprising the radiating unit. The radiating unit comprises a first dipole, a second dipole and a balance-unbalance connector, wherein the first dipole comprises two first half dipoles, the second dipole comprises two second half dipoles, the first half dipoles comprise first radiating plates, the second half dipoles comprise second radiating plates, the first radiating plates and the second radiating plates are in a shape that two ends are contracted, and two sides in the middle outwards extend, in addition, the middle is in a hollow shape, and the upper ends of the two first radiating plates and the two second radiating plates are jointly in insulation connection with a loading sheet. The radiating unit and the array antenna have the advantages that two ends of a first radiating body and a second radiating body are contracted, two sides in the middle outwards extend, the middle is in a hollow shape, the upper ends of the first radiating plate and the second radiating plate are provided with loading sheets, the impedance bandwidth of the radiating unit can be greatly improved, in addition, through the use of the loading sheets, the convergence of the radiation pattern of the radiating unit can be improved, and the structure is also very simple.

Description

technical field [0001] The invention relates to the technical field of dual-polarization radiation units, in particular to an ultra-wideband dual-polarization radiation unit and an array antenna including the radiation unit. Background technique [0002] With the rapid development of mobile communication technology and the coexistence of multiple systems and systems, the requirements for base station array antennas are getting higher and higher, and antenna integration and broadband have become the development trend. In the common frequency band of dual-polarized directional base station array antennas, the working frequency of DCS network is 1710MHz~1800MHz; the working frequency of PCS is 1850MHz~1990MHz; the working frequency of UMTS is 1920MHz~2170MHz; For development, in reality, there is a need for an ultra-broadband antenna (relative bandwidth 44.9%) that can fully cover the working frequency of 1710MHz to 2700MHz, which can cover all the above network standards and m...
