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.
