Problems solved by technology

[0003] However, the patents retrieved above also have deficiencies, and the horizontal polarization bandwidth cannot meet the bandwidth required by the current 3G (1G)
In addition, the horizontal polarization of Jingxin mode and Catherine mode are both side-fed, which restricts the vertical polarization out-of-roundness, and the vertical polarization roundness is deformed at some frequency points

Abstract

The invention discloses an integrated dual-polarization ceiling antenna which comprises a reflection plate, a vertical polarization feed cable, a vertical polarization feed plate, a radiation cup, a horizontal polarization feed cable and a horizontal polarization feed plate. The reflection plate is grounded, the radiation cup is composed of a barrel-shaped body and a cone at the bottom of the barrel-shaped body, a plurality of gaps parallel to the axial direction of the barrel-shaped body are distributed on the barrel wall of the barrel-shaped body at intervals in the circumferential direction, and the horizontal polarization feed plate is arranged in the barrel-shaped body. Due to the fact that the horizontal polarization feed plate moves into the barrel-shaped body from the top of the barrel-shaped body, bandwidth is greatly increased. Due to the fact that the vertical polarization feed plate is arranged outside the cone of the radiation cup and electrically connected with the bottom of the cone, the horizontal polarization feed cable penetrates into the bottom of the radiation cup and is electrically connected with the horizontal polarization feed plate, and the barrel-shaped barrel of the radiation cup is grounded, the horizontal polarization feed cable is prevented from penetrating through the side wall of the cone of the radiation cup, and the problem that vertical polarization roundness is abnormal at part of frequency points is solved.

Description

technical field [0001] The invention relates to an antenna, in particular to a dual-polarization ceiling antenna. Background technique [0002] The existing dual-polarization ceiling antenna is mainly the Hongxin mode. The main disadvantages of the Catherine model, Comba model, and Hongxin model are the complex structure and low isolation. Although the structure of the Catherine mode is simple, but the horizontal polarization bandwidth is narrow, it cannot meet the new needs. The structure of the Jingxin mode is slightly similar to that of the Catherine mode, and the horizontal polarization is integrated with the vertical polarization. The structure is simpler than the Hongxin mode. The Catherine mode is slightly more complicated, but the horizontal polarization bandwidth has been improved, and the isolation is better than the former two. The patent document of the top antenna, this patent includes the first joint, the second joint, the metal reflector, the inner conductor...
