|1. (WO2017152349) INTEGRATED DUAL-POLARIZATION CEILING ANTENNA|
|Applicants:||GUANGDONG MIKWAVE COMMUNICATION TECH. LTD.
|Title:||INTEGRATED DUAL-POLARIZATION CEILING ANTENNA|
Disclosed in the present utility model is an integrated dual-polarization ceiling antenna. The integrated dual-polarization ceiling antenna 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 consists of a barrel-shaped body and a cone at the bottom of the barrel-shaped body, multiple 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 disposed in the barrel-shaped body. Because the horizontal polarization feed plate is moved from the top of the barrel-shaped body into the barrel-shaped body, the bandwidth is greatly increased. Because the vertical polarization feed plate is disposed outside the cone of the radiation cup and is electrically connected to the bottom of the cone, the horizontal polarization feed cable penetrates into the bottom of the radiation cup and is electrically connected to 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, thereby resolving the problem of distortion of vertical polarization roundness at part of frequency points.
